Get just LAN IP without all the extra stuff

I just needed to store the LAN IP (for ipv4) in a variable for a specific task in a bash script. I figured I'd share. I sent it to a variable with VAR=$(stuff) and used it later on. I put the exit 0 in the if statement to make it so that it breaks if there are more than one IPv4 addresses assigned. I only wanted the first one. Edit: Bear in mind, my network mask is a double digit number so if you have a smaller nw mask you'd need to edit the sed statement. Show Sample Output

random xkcd comic

i sorta stole this from http://www.shell-fu.org/lister.php?id=878#MTC_form but it didn't work, so here it is, fixed. --- updated to work with jpegs, and to use a fancy positive look behind assertion.

This runs the uptime command every 30 seconds to avoid an SSH connection dropping due to inactivity. Granted there are better ways of solving this problem but this is sometimes the right tool for the job.

DVD to YouTube ready watermarked MPEG-4 AVI file using mencoder (step 2)

purge all packages marked with 'rc'

After you install/remove lots of packages, there are many packages marked with 'rc'. This script help you to purge these packages, it will save some spaces from your disk.

ls -qahlSr # list all files in size order - largest last

I find it useful, when cleaning up deleting unwanted files to make more space, to list in size order so I can delete the largest first. Note that using "q" shows files with non-printing characters in name. In this sample output (above), I found two copies of the same iso file both of which are immediate "delete candidates" for me.

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Print a list of all hardlinks in the working directory, recursively

libpurple likes to hardlink files repeatedly. To ignore libpurple, use sed: | sed '/\.\/\.purple/d'
