Burn an audio CD.
My variation on an audio burning command from commandlinefu - this one doesn't crap out if you want to burn a CD in a directory whose permissions don't allow it, and instead rips everything to /tmp. If you mount your music partition like I do using Samba, you probably don't have write permission inside that file system in order to create the temporary directory other audio burning commands here use. Not a bad idea to add cdrom to your groups, and /bin/eject with visudo.

Backup with versioning
Apart from an exact copy of your recent contents, also keep all earlier versions of files and folders that were modified or deleted. Inspired by EVACopy http://evacopy.sourceforge.net

List last opened tabs in firefox browser

find sparse files
Prints the path/filename and sparseness of any sparse files (files that use less actual space than their total size because the filesystem treats large blocks of 00 bytes efficiently).

Change a specific value in a path
Awk replaces the value of a specific field while retaining the field separator "/" .

Install pip with Proxy
Installs pip packages defining a proxy

restoring some data from a corrupted text file
man tac When there is a bad block in the middle of your file, you can see its begninning with `cat' and its end with `tac'. But both commands terminates with an error. So this sequence rebuilds a new file without badblock.

set desktop background to highest-rated image from Reddit /r/wallpapers
You'll need "feh" to set the background from the commandline. Install with "apt-get install feh" Thanks to the Redditors on this thread: http://www.reddit.com/r/linux/comments/bira4/is_there_a_linux_version_of_this_preferably_a/

Make sure a script is run in a terminal.
Exit with error if script is not run in a terminal

Print lines in a text file with numbers in first column higher or equal than a value
A text file contains thousands of numbers. This command prints lines were the number is greater or equal than a specified value (134000000).
