Shell Script Repository
Feel free to download and use any of the scripts found here for your own use. They are distributed under the terms of the GNU General Public License. These scripts have been written over a large period of time. Some are complex, some are simple. Some are elegant, some are quick hacks. Some are for Linux, others Solaris, etc. I suppose what I'm trying to say is your mileage may vary! This is just a snapshot of what's in my $HOME/bin directory at the moment!
As well as the repository, check the Tips and Tricks archive for more code snippets, scripts and useful information.
For your convenience (I think....) all scripts will open in a new browser window when you view them. This should make comparing and contrasting scripts a bit easier.
If you would like a complete archive of all the following scripts, please download the tarball.
