Windows Vs Linux – One more time

Fri, 07 Apr 2017 07:07:25 +0000

Image via Wikipedia

One of the most written and commented articles has to be Linux vs Windows (of course there are competitors like vim vs emacs) but none has been covered so much as Linux vs Windows. So, what am I going to write here which is not covered earlier in so many other posts. Well a little different perspective 🙂

tracer – trace outdated files on your system

Thu, 30 Apr 2015 14:17:43 +0000

Tracer finds outdated running applications in your system.

Home page : Tracer Home page.

To install :

sudo dnf install tracer

Once you have done that, after every dns update/upgrade you would see a list of process’s that need to be restarted. If you want to find manually, then just :

sudo tracer

nautilis fork ( File manager ) with tree view in sidebar.

Sun, 09 Feb 2014 00:49:09 +0000

Was searching for this for sometime now, finally found it.

sudo yum install nemo
sudo yum list nemo*

First just install nemo. Configure nemo not to interfere with default desktop and also make it default handler. So, here are the settings that would do it.

gconftool-2 --set  /desktop/gnome/applications/component_viewer/exec --type 'string' 'nemo "%s"'
gconftool-2 --set  /desktop/gnome/url-handlers/trash/command --type 'string' 'nemo "%s"'
gsettings set org.nemo.desktop show-desktop-icons false

Now, if you need more functionality in file manager then check the list of nemo packages from the output of second command of yum. It has plugins like file preview and so on. Install and enjoy.

sxiv – image viewer

Fri, 06 Dec 2013 01:13:06 +0000

sxiv is a nice alternative to feh. It is very light weight and quite useful. Here is the description:

Description :
sxiv is an alternative to feh and qiv. Its only dependency besides xlib
is imlib2. The primary goal for writing sxiv is to create an image viewer,
which only has the most basic features required for fast image viewing (the
ones I want). It works nicely with tiling window managers and its code base
should be kept small and clean to make it easy for you to dig into it and
customize it for your needs.

bash – using the vi mode more effectively.

Fri, 22 Nov 2013 01:50:24 +0000

You can first set the bash mode to vi. This will enable some vim like features to bash. So, add this to .bashrc :

set -o vi

Once, you have done that then its time to get more out of the vi mode. First, check some things and set some interesting stuff.

zswap – compcache, compressed swap for better performance

Sun, 17 Nov 2013 01:45:06 +0000

First, here is a link to article on compcache.

http://code.google.com/p/compcache/wiki/CompilingAndUsingNew

zswap is already in the kernel and you can see the documentation in the kernel documentation. Here is the name of the file if you need:

/usr/share/doc/kernel-doc-$(uname -r)/Documentation/vm/zswap.txt

Here is the overview, in case you do not want to install kernel-doc

Overview:

Zswap is a lightweight compressed cache for swap pages. It takes pages that are
in the process of being swapped out and attempts to compress them into a
dynamically allocated RAM-based memory pool. zswap basically trades CPU cycles
for potentially reduced swap I/O. This trade-off can also result in a
significant performance improvement if reads from the compressed cache are
faster than reads from a swap device.

Home grown mail scheduler with bash script and cron

Fri, 04 Oct 2013 01:04:35 +0000

If you are using Linux (Fedora/Ubuntu or anything else) then you do get a lot of tools and one of them is cron. Very very useful. Just write some script that can do the task for you, put it in cron and forget it. So, here is a home grown way to schedule mails.

First, copy this script below:

#!/bin/bash -
#===============================================================================
#
#          FILE: sched_mail.sh
#
#         USAGE: ./sched_mail.sh
#
#   DESCRIPTION:
#
#       OPTIONS: ---
#  REQUIREMENTS: ---
#          BUGS: ---
#         NOTES: ---

#      REVISION:  ---
#===============================================================================

mailfile="~/mail"
if [[ $(wc -l $mailfile|awk '{print $1}' ) -ge 5 ]]
then
    to=$(grep ^To: $mailfile|sed 's/To: //')
    echo "Good to send mail... to = $to"
    sendmail -t <$mailfile
    echo "once mail is send, delete the contents of file"
    echo "sed -i '4,$ d' $mailfile"
fi

Now, create a file called mail in your home directory, with the following contents:

force recheck on reboot – fsck

Fri, 27 Sep 2013 00:34:48 +0000

If you want to force a fsck re-check on reboot, then just

touch /forcefsck

find more information on ext2/3/4 filesystem

In my previous post on check filesystem regurlarly, I mentioned tune2fs. That tool give quite a lot of information. But just in case, you did not find what you are looking for in the output, then you can get much more information on these partitions with the dumpe2fs command.

Delete all but some directories

Fri, 16 Aug 2013 01:06:05 +0000

I think, like me, you would have faced a lot of situations, where you wanted to delete all the files or directories in a location, leaving only the required files/directories. So, I have a directory containing lots of files/directories and I want to delete most of them except some 5/10 of them, how to I do it.

I finally wrote a small script to do that. First save list of files that you do not want to delete in file called “listnames” and then execute the below script. This will give you the rm commands that you need to execute. If you want you can execute the rm command from the script, but to be able to review, I just have the commands echoed.

configure firewall – the easy way.

Wed, 24 Apr 2013 00:50:17 +0000

It is good practice to keep iptables/firewall enabled. But configuring it is difficult, do you agree. Not any more 🙂

Install firewall-config

sudo yum install firewall-config

This will install a GUI application, which you can run with “Firewall” application in the dash or with “firewall-config” in terminal. It is pretty straight forward to use this tool, even if you don’t have much knowledge on Firewall/iptables.

dwb – keyboard driven browser

Mon, 08 Apr 2013 01:35:36 +0000

First off, install using the command

sudo yum install dwb

Now for the description:

dwb is small webkit-based web-browser in the spirit of tiling window managers,that aims to be mostly keyboard-driven.

I liked the fact that it does well what it tries to do and pretty good at being fast.

steam on Linux – for Fedora

Fri, 22 Feb 2013 00:35:25 +0000

I was trying to get steam on linux on my Fedora box. Headed over to steam website, but was astonished to find only Ubuntu client over there. A little googling presented me with the developer website blog of valvesoftware.com. So, here is the link for you, just in case you are searching for the same:

quick bash script for datewise backup of directory

Wed, 12 Dec 2012 00:50:29 +0000

I was working on something and the data was very critical and needed backup. I wrote a bash script to back up the data every 5 hours with cron and bash script. Thought I will share that with you. Here is the script.

#!/bin/bash - 
#===============================================================================
#
#          FILE:  backup.sh
# 
#         USAGE:  ./backup.sh

backupf=( a b c d) #Here you need to specify the directory you need to backup.
bkupdir="/tmp/backup/$(date +%Y)/$(date +%m)/$(date +%d)" #Here you can change the basedir for the backups
mkdir  -p $bkupdir
sudo tar cvfz $bkupdir/bkup_$(date "+%Y%m%d_%H%M").tgz $backupf[*] #Remove sudo if you do not need it.
echo "Backup created in dir $dir"

And then just add it to cron as “00 */5 * * * /home//bin/backup.sh”. Change the path if it does not match what is given here.

Allow incoming/outgoing ports on iptables

Tue, 27 Nov 2012 00:22:23 +0000

Schematic for the packet flow paths through Linux networking and Xtables (Photo credit: Wikipedia)

Last couple of years, I just used to disable iptables on my system, this time I decided not to disable it and keep it enabled.

So far so good, now comes the tricky part, I have http server enabled on my system and since this is on local network with already firewall and other security in place so I can allow all incoming to my system and similarly I need to enable XDMCP outgoing. So, I can add the rules like this :

Shortcut to run current command with sudo in bash

Thu, 20 Sep 2012 02:27:56 +0000

For me, I mostly forget to add “sudo” to the command until the time I am actually supposed to run it. Also sometimes, on some systems, bash completion does not work as expected with “sudo”. With these in mind, I wanted something such that when I have completed the command, I could insert sudo in the begining of the command without much ado. So, finally this is what I came up with in my “~/.inputrc” file. Note: If you don’t have this file, then simply create this file.

gqlplus – sqlplus with readline (tab completion)

Fri, 03 Aug 2012 03:04:58 +0000

Tab completion is something which is missing in the sqlplus and if you have lot of tables with long names or lot of columns then it is sufficiently difficult to type them 🙂

Here is a solution for this problem. Download and install gqlplus. gqlplus is a replcement for sqlplus which supports completion for commands/tablenames and column names. Quite useful.

If you have done a new installation of Ubuntu or Fedora, then yuou know you have to search all kind of blogs to find out what all to install. So, here is a easier way to do that. Just run this script, it will install some applications which are mostly a “MUST” for all the installations. And the list of applications that are installed are :

Install the utility:

sudo yum install rpmconf

Description:

Description : This tool search for .rpmnew, .rpmsave and .rpmorig files and ask you what to do

with them:

Keep current version, place back old version, watch the diff or merge.

And finally run the utility:

sudo rpmconf -a

and if there is a conflict or rpmsave or rpmnew file, then you will see something like this:

Array of all possible colors in bash script

Mon, 07 May 2012 02:17:18 +0000

Sometime back, we had looked at using colors in bash script and here is a way to create a array of all the colors.

            done
        done
        echo
    done
    echo
done

You can add this script to any script of your choice and you have all the 256 colors available to you in the script without additional coding. Happy coding.

eval export$(sed's/\o000/\n/g;' < /proc/$gnome_session/environ |grep DBUS_SESSION_BUS_ADDRESS)

So, once you have done that you have the correct environment to use the X display and thus you can start the gnome-shell as well or do any other fancy thing that you want 🙂

colors in bash scripts

Mon, 30 Apr 2012 03:52:29 +0000

Colours (Photo credit: CherrySoda!)

I have been trying to understand the color codes for bash for a pretty long time, but somehow never got time to understand this clearly. So this time around when I was writing a script to analyze some logs. I thought I will give it a go and finally understood some part of this.

So, first we will start with this script. This is taken from here.

systemadm – simpler way to manage the service files for systemd

Tue, 17 Apr 2012 02:43:09 +0000

Once the systemd unit and service files have come into being, understanding of the system services have changed a little bit and it might require some time to understand the cli tools for managing these services and units. That being the case, systemadm comes to rescue. This is a simple tool which :

Graphical front-end for systemd.

For installation :

You will need to setup the rpm-shere repo for this.

Tue, 21 Feb 2012 04:42:41 +0000

You would have used top at some point of time. Did you not wish that instead of just the processes it list all the vital statistics of the system as a whole. How good it would be to see the Memory, Net, Processes and Disk usage on the same screen. Well then you should take a look at glances. Here is how it looks:

Last article I talked about tora installation from the sources, but if that is too much for you then you can use this one liner:

But if you like the hard way out, then you can always try this.

Sometime back I had posted a article on Tora on Fedora. But that was a while back and things have progressed and we already have Fedora 16 (aka Verne).

So, awhile back I installed Tora on my Fedora 16 and here are the steps to do so:

First get the Tora sources from sourceforge.net . Download the source tar file and extract the same.

Color disk usage on Fedora

Sat, 21 Jan 2012 12:43:40 +0000

For this tip, you would need to setup the rpm-shere repository. You can get the information here. Once you have done that you need to install the cdu package with the following command:

sudo yum install cdu

And then you can use “cdu” to view the disk usage in all beautiful colors with the command:

cdu

and the output looks like this:

I was looking for something to monitor few details on the server. I thought about quite a lot of applications, some open source and some scripts developed in house. But my requirements were quite petty and the scripts and applications were quite heavy. So, I thought why not conky :).

So, with some quick work on conky script, I was able to get what I wanted and here it is for all of you.

rpmorphan – deborphan for the rpm based distros.

Wed, 07 Dec 2011 11:02:15 +0000

Lets first install the rpmorphan package:

        &nbsp;<span class="kw2">sudo</span> <span class="kw2">yum install</span> rpmorphan
      </div>
    </td>
  </tr>
</table>

and here is the description of the package:

rpmorphan finds "orphaned"[1] packages on your system. It determines which packages have no other packages depending on their installation, and shows you a list of these packages. It intends to be clone of deborphan Debian tools for rpm packages.

It will try to help you to remove unused packages, for example:

quadkonsole – multiple consoles to make your life easier

Mon, 21 Nov 2011 10:46:58 +0000

First lets install quadkonsole:

yum install quadkonsole

Now, to launch the quadkonsole, just type quadkonsole in the run box (appears with Alt+F2).

You will by default see 4 console windows in single window but you can change that with command line options like so:

quadkonsole --rows 4 --columns 4

This will initiate windows with 16 consoles. How cool is that.

If you are working on recent versions of the *nix OS like Fedora or Ubuntu then you would know about the commad ssh-copy-id. But if you land up using one of the older versions like Solaris or something where the command is not present, then probably you need a simpler solution to this. One of the simplest solution is with a lot of assumtions, simply copy the id_rsa file to remote server and hope it works. And here is a script to do just that:

Ah well…its very interesting and very useful.

Some explanation:

!# – means the current command (similar to !! being the last command)

$ – represents the last parameter

:s – is used for substitution.

For all those who used to keep complaining about the bottom panel of Gnome which used to show a list of windows, you can get it back with bmpanel2 (there are lot of other options too, but this one is light.). You can have themes for the panel also.

And the best part about using gnome-shell is that I always getting a feeling that I now have more space on the Desktop. And, thus conky looks good too on the Desktop. Here’s a screenshot.

Wed, 05 Oct 2011 15:18:56 +0000

If you are looking for some nice conkyrc files, then you can head over to :

In this thread you can see some very nice conkyrc files with screenshots. You can browse through the thread and get the one that you like. But if you are like me and would like to download all of them to see the features and commands in each of them then you would need to copy each of these files and paste them separately. But if you have to do everything manually then there’s not much of being on Linux 🙂

I am testing some of my scripts to work on a very old system and there the versions of the most popular applications are very old, real old :(. So, some of things that I am very used to since last couple of years, do not seem to work as expected and I need to keep verifying a lot of things on the server, very inconvinient to keep testing the script on the server (need to connect on VPN) just to test some very simple things.

better bash debugging

Fri, 16 Sep 2011 08:00:08 +0000

I was trying to debug some bash scripts yesterday and learnt something new 😉
There are lot of things in bash that you can use to debug and to start with you can enable xtrace mode as follows:

set -x

With this set you will see that all the commands are printed along with all other information as they are executed.
This you can do for any line or for the function or for the whole script. Once you set the option you can turn it

Gnome 3 shell themes

Fri, 12 Aug 2011 00:33:31 +0000

If you are using gnome-shell and are bored with the same default theme then read on…. 🙂

By default changing the default theme requires that you modify the files yourself or copy few files to the required directories. Well, if this is not in your scheme of things for changing the theme, a very simple task. Now, you can simply do this with gnome shell extensions.

bash completion

Tue, 09 Aug 2011 03:36:37 +0000

I was working on some functions in bash to make my life easier and realized that if I added custom completion to my functions, it will be really good. So I headed over to google and searched for what I wanted. I did get a lot of information on bash completion but not a single concrete example that could help me do what I wanted. So, with the help of man pages and some results from the Google pages, I was finally able to accomplish what I wanted. So here it is:

Installing Full Blin g theme on N900

Wed, 03 Aug 2011 03:53:57 +0000

I was going through the post : http://talk.maemo.org/showthread.php?t=46739
and found the theme quite intruging but not complete to the point where I can download the deb file and install it in /usr/share/theme/ dir with simple commands “apt-get” or at max just use mkdir command to create the dir and dump everything in that dir. So, I wrote this couple of bash one liners to copy the required files to my N900.

Fast and bleeding edge Firefox.. version 7

Thu, 30 Jun 2011 01:19:39 +0000

Firefox 7.0 nightly builds have started and it seems to be quite fast. So, if you dont care about some sites not opening or once in a while your browser crashing, been using for 2 days on Windows , has not crashed so far and worked on all sites so far :), then you should install the Nightly build.

Head over to the nightly build site and install the appropriate build for your OS.

GPG error on N900 when doing update on command line

Wed, 22 Jun 2011 01:57:01 +0000

Image via Wikipedia

If you have added some extra repositories to your Nokia N900 and are trying to do something ( like update, install or any other apt-get operation) you might see some errors or warnings related to the GPG keys. The errors would come because the Public keys for the reporisitories are not present in the gpg database 🙂

Installing Bling Theme on N900

Sat, 18 Jun 2011 18:53:56 +0000

Image via Wikipedia

There is a very nice theme for N900 and it is called Bling theme. There is a problem though with the theme, the theme still does not have a installable .deb file, and thus the files need to be directly copied to “/usr/share/icons” and you have to manually do the mkdir and all such command in the terminal in a N900, which does not seem familiar to quite a lot of people using N900. So here, is for the benefit of all, I am posting a script that can do the job. The one lines can be run from any bash script (Linus/Windows with cygwin/Mac or even N900). Though the one liners should be self explanatory, if you have a doubt, feel free to ping me.

faster bash operations on files with File Descriptors.

Sat, 11 Jun 2011 02:11:53 +0000

I was writing a bash script that would do some operations and read and write to file. Seems that that was pretty simple with

  <td>
    <div class="text codecolorer">
      while read line<br /> <br /> do<br /> <br /> done<file
    </div>
  </td>
</tr>

5

and then use redirection operations like “>” and “»” to write to file. Done with the script pretty fast. So far so good, when I went for real life tests, no one was interested in using it, why? Simple, it was simply taking too long. The file was reading about 10K lines and writing about 50 lines and was taking about more than 10 minutes.

N900 starts showing junk characters

Wed, 08 Jun 2011 01:50:16 +0000

Well, sometime back I bought N900, some snaps here. And sooner than later I started playing with it. In an effort to reduce the disk usage for the “/” (root) partition, I removed some packages that were taking too much of space and managed to get the mobile to a stage where a lot of applications started displaying strange and junk characters and also cannot use package manager any more…errors reported.

I have been thinking of buying the “N900” Nokia mobile for quite sometime but for certain reasons could not get my hands on this mobile so far. Finally couple of days back, I got my hands on this beautiful and powerful piece of software and hardware.

10 Useful Sar (Sysstat) Examples for UNIX / Linux Performance Monitoring

by Ramesh Natarajan on March 29, 2011

Using sar you can monitor performance of various Linux subsystems (CPU, Memory, I/O..) in real time.

Using sar, you can also collect all performance data on an on-going basis, store them, and do historical analysis to identify bottlenecks.

Sar is part of the sysstat package.

This article explains how to install and configure sysstat package (which contains sar utility) and explains how to monitor the following Linux performance statistics using sar.

The Ultimate Guide to Getting Support on Linux
Installing Linux has become effortless to the extent that anyone with a little knowledge of computers can get a Linux machine up and running instantly. However, many of them throw in the towel when faced with even the slightest of glitches. The main reason for this is the belief that Linux doesn’t offer any kind of support.

Other problem users face is that the regular technician who repairs their computer refuses even to touch a machine that’s running Linux. So, if you are one of those users disgruntled after encountering a multitude of problems with a fresh Linux install — don’t panic and read on to know some ways in which you could get support for your Linux installation.

Slackware Linux 13.37 RC 3.1415926535897932384626433832

Slackware released the next version a few days back and guess the complete name : Slackware Linux 13.37 RC 3.1415926535897932384626433832. You must be crazy to tell the complete version to anyone.

Gnome Tips

Fri, 25 Feb 2011 13:03:43 +0000

Add/Edit GDM Sessions

Each session is a *.desktop file located at /usr/share/xsessions.

GDM appearance

You can change background image, gtk/icon theme by hands (as described at Gnome_2.28_Changes#Configuring_gdm_2.28), or you can use gdm2setup from the AUR.

Tweaking

If your gnome applications seem sluggish and gnome hangs at start-up after killing the previous session, it’s likely you haven’t set your /etc/hosts file correctly and your /etc/hosts file includes:

127.0.0.1       localhost.localdomain     localhost      YOURHOSTNAME

Then run “/bin/hostname YOURHOSTNAME” and “/sbin/ifconfig lo up” as root.

Install a fully functional terminal server capable of accepting connections from RDP(Windows).

Sun, 12 Dec 2010 03:28:43 +0000

Inoformation on xrdp:

The goal of this project is to provide a fully functional Linux terminal server, capable of accepting connections from rdesktop and Microsoft’s own terminal server / remote desktop clients.

  <td>
    <div class="text codecolorer">
      &nbsp;sudo yum install xrdp
    </div>
  </td>
</tr>

There is not much configuration needed for this so I will not go into details. If you are stuck with something though, you can ask in the comments for the post.

intercept stdout/stderr of another process or disowned process

Tue, 23 Nov 2010 12:51:27 +0000

The command is definately going to save your day if you have disowned the process by mistake. Only uses strace so might as well work on Solaris also, though not tried it.

intercept stdout/stderr of another process or disowned process

  <td>
    <div class="text codecolorer">
      strace -e write=1,2 -p $PID 2>&1 | sed -un "/^ |/p" | sed -ue "s/^.{9 }(.{50}).+/1/g" -e 's/ //g' | xxd -r -p
    </div>
  </td>
</tr>

Useful to recover a output(stdout and stderr) “disown”ed or “nohup“ep process of other instance of ssh.

Broadcast your shell thru port 5000

Sat, 20 Nov 2010 12:47:31 +0000

Broadcast your shell thru port 5000

  <td>
    <div class="text codecolorer">
      mkfifo /tmp/fifo;(nc -q0 -l 5000 < /tmp/fifo &);script -f /tmp/fifo

  </td>
</tr>

run

  <td>
    <div class="text codecolorer">
      nc yourip 5000
    </div>
  </td>
</tr>

elsewhere will produce an exact same mirror of your shell. This is handy when you want to show someone else some amazing stuff in your shell without giving them control over it.

All of us have been benefited by Linux in some way or other and this is due to all the work that is being done by so many organizations and people around the world. I would like to spare some time to tell you about my initiative to raise 100$ for Linux Foundation. Please visit my donation page or click donate on the widget in the bottom of the page. The Linux Foundation will highly appreciate it and so would I.

Print all environment variables, including hidden ones

Tue, 09 Nov 2010 14:46:15 +0000

Print all environment variables, including hidden ones

  <td>
    <div class="text codecolorer">
      for _a in {A..Z} {a..z};do _z=${!${_a}*};for _i in `eval echo "${_z}"`;do echo -e "$_i: ${!_i}";done;done|cat -Tsv
    </div>
  </td>
</tr>

This uses some tricks I found while reading the bash man page to enumerate and display all the current environment variables, including those not listed by the ‘env‘ command which according to the bash docs are more for internal use by BASH. The main trick is the way bash will list all environment variable names when performing expansion on ${!A*}. Then the eval builtin makes it work in a loop.

Linux>1% Campaign. Prove that we are more than 1% !

Linux>1% Campaign. Prove that we are more than 1% !

At http://www.dudalibre.com they are running a campaign to make every owner of computers running Linux register. The aim is to prove that the general assumption, that only 1 % of all computers run Linux is wrong. Everyone is needed if this effort is going to succeed.

I voted for my distro Fedora, hope you do the same for your linux distribution and prove that Linux does run on high number of desktop.

http://ninite.com/linux/makeuseof – very good collection of utilities for .deb based distro’s

Fri, 08 Oct 2010 02:53:22 +0000

Head over to http://ninite.com/linux/makeuseof and you will find a nice utility created by the makeuseof guys. This will allow you to select the applications that you want to install and once you have made the selection you can download the unattended installer.

Well, to be frank with you I really do not see the need for this unless you don’t know how to add repositories or install simple stuff. Most of this (no, actually all of this except dropbox in my Fedora setup with the repositories that I have set). Now for one application why would I do that if that was available for Fedora. Any-ways pretty good for newbies, still.

bash script to run a command and take screenshot in every loop.

Fri, 24 Sep 2010 16:02:14 +0000

Couple of days back, I had posted a command to display a stop timer with bash and echo. There I had also put the following gif file:

Here the tricky part was to capture the jpg’s to create the gif file.

Preparation:

Rename the terminal to aka – amit-capture

Execute the command once with the import command and check the output and jpg’s

bash – echo command with option to display the output on the same line.

Tue, 21 Sep 2010 15:15:05 +0000

Here is a nice little trick to display the output in the same line :

  <td>
    <div class="bash codecolorer">
      &nbsp;<span class="kw3">echo</span> <span class="re5">-ne</span> <span class="st0">"output\<span class="es1">\r</span>"</span>
    </div>
  </td>
</tr>

The trick here is simple, first we disable the <a class="zem_slink" title="Newline" rel="wikipedia" href="http://en.wikipedia.org/wiki/Newline">newline printed by <a class="zem_slink" title="Echo (command)" rel="wikipedia" href="http://en.wikipedia.org/wiki/Echo_%28command%29">echo command with the ”-n” option and then we enable the interpretation of the <a class="zem_slink" title="Backslash" rel="wikipedia" href="http://en.wikipedia.org/wiki/Backslash">backslash characters with the ”-e” option. As the ”\r” is used as <a class="zem_slink" title="Carriage return" rel="wikipedia" href="http://en.wikipedia.org/wiki/Carriage_return">carriage return which brings you to the start of the line without the newline (like in <a class="zem_slink" title="Typewriter" rel="wikipedia" href="http://en.wikipedia.org/wiki/Typewriter">typewriter), we will use the same to get the desired effect. So, if you wanted a stopwatch for a 100 seconds on the console then this simple bash <a class="zem_slink" title="For loop" rel="wikipedia" href="http://en.wikipedia.org/wiki/For_loop">for loop would do the same:

Fedora Linux – Display information about users currently logged on – whowatch

Sat, 04 Sep 2010 19:01:14 +0000

Here is description of program/utility to display the currently logged in user in a Linux box (tried on Fedora 13 Goddard):

Whowatch is an interactive console utility that displays informations about the users currently logged on to the machine, in real time. Besides standard information (login, tty, host, user’s process) you can see type of login (ie. ssh, telnet). You can also see selected user’s processes tree or all system processes tree. In the process tree mode there is ability to send INT or KILL signal to selected process.

Remove some path from the PATH variable temporarily.

Sat, 04 Sep 2010 15:02:08 +0000

How many times has it happened to you that you are working on some linux platform (like Fedora/Ubuntu/CentOS etc) and suddenly you see that you need to remove some path from the PATH variable so that a script is executed from some other path. It really difficult to do this if the path is too long and if you end up doing this couple of times. If that is the case, then the below script is for you 🙂

Use the last command\’s output as input to a command without piping and bind to it to a key sequence in bash.

Wed, 01 Sep 2010 18:42:55 +0000

Use the last command’s output as input to a command without piping and
bind to it to a key sequence in <a class="zem_slink" title="Bash (Unix shell)" rel="homepage" href="http://tiswww.case.edu/php/chet/bash/bashtop.html">bash.

My comment : fc is the fix command of the bash builtin.
This is similar to using `!!` or

tee to a file descriptor

Fri, 13 Aug 2010 03:22:44 +0000

tee to a file descriptor

`1`	`$ tee >(cat – >&2)`

the tee command does fine with file names, but not so much with file descriptors, such as &2. This uses process redirection to tee to the specified descriptor.

In the sample output, it’s being used to tee to stderr, which is connected with the terminal, and to wc -l, which is also outputting to the terminal. The result is the output of bash –version followed by the linecount

Linux command to repeat a string n times - Super User

Are you swapped? Increase the performance of Linux machine.

Wed, 14 Jul 2010 01:06:31 +0000

With the ever increasing cost of the Hardware, the amount of physical RAM available on the system is increasing day by day. For example, couple of years back, I had a system which was very high end Desktop with 256MB RAM and today I have a 2GB RAM Desktop. So, whats the point.

The Linux systems (right word should be kernel) are desiged to use both RAM and swap partition. Swap partition is a partition on Hard disk and is used mostly like RAM. Problem is that HDD access is always slower than RAM access and hence inherently, the system will work little slower even if you have enough RAM not to use swap. The term ”swappiness” is used to determine how the kernel should try to seam-balance between the use of RAM and swap. By default, most of the distro’s have a swappiness of 60. A higher value of swappiness means that the RAM will be swapped out faster.

Linux is just too open

Thu, 24 Jun 2010 20:51:32 +0000

The Problem with Linux is that it is forthright, open and honest. Now I know how much the editors here hate when I anthropomorphize an operating system, but it is fundamentally true.

Linux, in my view, remains almost too honest and too open.

Google staff dropping Windows for Macs, Linux PCs

Wed, 02 Jun 2010 01:53:34 +0000

For those who keep saying this is not the year of linux and probably it will never be 🙂

Google is abandoning the use of Windows by its staff as it\’s too much of a security threat, multiple staffers said Monday night. Recent concerns about Chinese hacks have the search firm requiring either a Mac or Linux for all new recruits to provide better security. Those who want Windows now often require explicit approval from executives and may not have any choice on desktops where it\’s only an option for notebooks.

I was testing a program which crashing every now and then. It is very difficult in such scenarios to keep looking for the <a class="zem_slink" title="Core dump" rel="wikipedia" href="http://en.wikipedia.org/wiki/Core_dump">core file or keep checking for the running process.

Ubuntu Sucks Like a Shopvac and Other Linux Rants

Tue, 16 Mar 2010 02:25:46 +0000

Almost 100 articles and blogs on the topic of “ubuntu sucks” were published in the past month alone, and about as many were published that unequivocally state Windows is better than Ubuntu.<table border="0">

<span style="font-size: x-small;">
But upon closer examination, I found that a substantial portion of these negative reactions to Ubuntu stem from unrealistic comparisons.

Almost all of the hurdles people seem to have when switching from Windows to Ubuntu appear to be errors in judgment and assessment, rather than actual problems with the OS.

Splitting strings with IFS

Thu, 04 Feb 2010 15:58:43 +0000

Today I want to discuss splitting strings into tokens or “words”. I previously discussed how to do this with the <a href="http://bashcurescancer.com/reading-a-file-line-by-line.html">IFS variable and promised a more in depth discussion. Today, I will make the case on WHY to use IFS to split strings as opposed to using a subshell combined with <a class="zem_slink freebase/en/awk" title="AWK" rel="homepage" href="http://cm.bell-labs.com/cm/cs/awkbook/index.html">awk or cut.

I wrote this script which reads the /etc/password file line-by-line and prints the <a class="zem_slink freebase/en/user" title="User (computing)" rel="wikipedia" href="http://en.wikipedia.org/wiki/User_%28computing%29">username of any user which has a UID greater than 10 and has the shell of /sbin/nologin. Each test function performs this task 10 times to increase the length of the test:

EncFS – Simple article to use Encrypted filesystem in Linux

Thu, 24 Dec 2009 07:37:10 +0000

A nice article here

EncFS is an easy-to-use, command-line tool for storing information in encrypted form. It’s not really a file-system, but it pretends to be one at the CLI. If you’ve been searching for a means of encrypting and decrypting your sensitive data easily, here it is.
User Level: Intermediate
EncFS is included with the distribution I’m using on the desktop, Ubuntu Dapper, so all I needed to do to install it was a few clicks in Synaptic. Look for the encfs package, and select if for installation. It should pull down all of the dependencies for the system. If you’re not so lucky, and your distro doesn’t include EncFS packages, you can download the latest tarball from a here and build it from the source. See the EncFS site for a dependencies.

5 Sites To Find Free Alternatives To Popular Software

Sat, 21 Nov 2009 02:13:26 +0000

And sometimes there are software you find irksome and think things could have been better. In any case, I always like to try out a few alternative software choices before I settle with any particular application mainly for two reasons: One, you would never know how good or bad the one you are using is until you try some alternatives and two: a bit of choice and competition can only be for the good of us users! Your motivation might be different: perhaps you want to find a free software that does the same task as the paid software you are using or maybe your favorite Windows application is not available on Mac or Linux.
