Easy ssh configuration with .ssh/config file

If you ssh to many hosts then you are aware of the pain that it takes to ssh with different username and hostname. There is an alias that you can creat with native ssh though. Here I will show you the same with an example.

  <td>
    <div class="text codecolorer">
      cat <<EOF >>~/.ssh/config<br /> Host <alias><br /> Username <user name><br /> Port <port number><br /> Hostname <hostname>
    </div>
  </td>
</tr>

You can optionally omit the parameters that you do not require explicitly. For example, if your port number is default then you can simply ignore the parameter.

Try all colors in xterm with script before setting the color

If you are looking for testing the colors on how they would look like in the xterm before you set the color then here is a small script for you.

  <td>
    <div class="text codecolorer">
      #!/bin/bash -<br /> #===============================================================================<br /> #<br /> #          FILE:  xterm_colors-test.sh<br /> #<br /> #         USAGE:  ./xterm_colors-test.sh<br /> #<br /> #   DESCRIPTION:  Test all the colors for xterm bg<br /> #<br /> #       OPTIONS:  ---<br /> #  REQUIREMENTS:  ---<br /> #          BUGS:  ---<br /> #         NOTES:  ---<br /> #        AUTHOR:   Amit Agarwal (amit.agarwal@amit-agarwal.co.in), aka<br /> #       COMPANY:  Individual<br /> #       VERSION:  1.0<br /> #       CREATED:  02/18/2011 01:02:51 PM IST<br /> #      REVISION:  1.0<br /> #===============================================================================<br /> <br /> cat /usr/share/X11/rgb.txt |sed 's/\([0-9]\{1,3\}[ \t]*\)\{3\}//'|sed 's/^ *//' >~/rgb.txt<br /> while read line<br /> do<br /> bg=$(echo $line)<br /> echo $line<br /> echo "Trying $bg color"<br /> xterm -bg "$bg"&<br /> sleep 5<br /> kill -9 $!<br /> done < ~/rgb.txt
    </div>
  </td>

This can be used in various ways but I will leave the choice to you. One option that I should probably still tell is :

what is vim in 6Kb..

If you thought that vim is very bloated and nothing abuot this editor can be small, then you are not alone. I was myself in the same bandwagon.

Well, I never thought that there could be anything about vim that can be explained in Kb’s, lest alone the complete vim features. But looks like vim.org had thought about this and thus came up with this. And here is the direct link to the vim in 6kb in English.

cd across parallel directories

All in one solution for all the scripts of vim from vim.org

For quite sometime now, I was looking for some console based program which would help me get the scripts from vim.org. A simple solution would have been to do a wget for the scripts. But since there are so many scripts coming up daily and with a need to search based on script ID and name of the script, I thought better to write a script that can do all of those things. Now, what was required was that the script should be either able to download this or add to the GLVS script. Also note that, I had done something similar in the past here. There are some additions in the below script. You can download a copy of the script get_vim_scripts. Or you can copy the script from below:

configuration for afraid-dyndns on Fedora and other similar distro.

First install afraid-dyndns with the command:

  <td>
    <div class="text codecolorer">
      sudo yum install afraid-dyndns
    </div>
  </td>
</tr>

Now open the configuration file /etc/afraid-dyndns.cfg and we need to change the following:

Notify = root@localhost # leave empty to suppress notifications
CacheFile = /var/cache/afraid-dyndns/IP
AccountHash =

For the Account hash, head over to http://freedns.afraid.org/api/ login and then click one of the XML or the ASCII links there. Once the page has loaded, look at the URL which is of form:
