Check file usage using fuser

There is a package called psmisc that provides a useful application fuser. The package provides the below (on fedora):

/sbin/fuser
/usr/bin/killall
/usr/bin/peekfd
/usr/bin/pstree
/usr/bin/pstree.x11

There are couple of options you can provide on the terminal to fuser. The main purpose of the binary is to check the process id of the process using the file. This can be useful if some file operation on a file is blocking something for you 🙂

Linux:Please Don\’t Show the Command Line to the Uninitiated (via postie)

Not long ago I had the opportunity to show off GNU/Linux to a friend. She&#8217;s been a lifelong Windows users and is just your average, non-technical computer user. She&#8217;d heard of this thing called “Linux,” but had never seen a Linux distro in use. So, I gladly booted up my laptop and also the desktop (we were at my house, my wife and I having one of our many cookouts) and showed her Linux Mint 7 via a live CD and also Ubuntu 8.10, which is installed on my family&#8217;s desktop.

Oracle GUI client on Linux with mysql support

I was looking for some nice client for Oracle and mysql. I did find mysql-administrator and navicat to be useful but this is much better. <a href="http://sourceforge.net/projects/tora/" target="_blank">Tora is the client that I am talking about. Installation did not take much time for me..

downloaded the instant client from oracle.com and then the tora rpm from sourceforge.net. Also downloaded the tora-mysql from http://rpm.pbone.net/index.php3/stat/21/year/2002/month/01/day/28

Then tried to install all the rpms found the rpms that were missing and installed them using yum. Once this is done install the downloaded rpms with &#8221;–nodeps&#8221; option of rpm.Put the entries in bashrc

A very nice article on firefox can be found here. Though written for Ubuntu should be applicable to all distro&#8217;s.
