Add an iptables rule on RH/CentOs before the reject

Copy specific files to another machine, keeping the file hierarchy
Notes: * Adjust the find command to your own filters. * The -P flag forces to keep absolute paths in the tarball, so that you can be sure that the exact same file hierarchy will be created on the second machine.

Prints per-line contribution per author for a GIT repository
Figures out total line contribution per author for an entire GIT repo. Includes binary files, which kind of mess up the true count. If crashes or takes too long, mess with the ls-file option at the start: git ls-files -x "*pdf" -x "*psd" -x "*tif" to remove really random binary files git ls-files "*.py" "*.html" "*.css" to only include specific file types Based off my original SVN version: http://www.commandlinefu.com/commands/view/2787/prints-total-line-count-contribution-per-user-for-an-svn-repository

Get the Volume labels all bitlocker volumes had before being encrypted
Get information of volume labels of bitlocker volumes, even if they are encrypted and locked (no access to filesystem, no password provided). Note that the volume labels can have spaces, but only if you name then before encryption. Renaming a bitlocker partition after being encrypted does not have the same effect as doing it before.

Configure second monitor to sit to the right of laptop
You'll need to make sure your xorg.conf permits a virtual screen size this big. If it doesn't then xrandr should return a suitable error message that tells you the required size.
