Swap a file or dir with quick resotre
This lets you replace a file or directory and quickly revert if something goes wrong. For example, the current version of a website's files are in public_html. Put a new version of the site in public_html~ and execute the command. The names are swapped. If anything goes wrong, execute it again (up arrow or !!).

open remote desktop connection without X
You can use it to connect to remote windows machine and start some scritps that need user login

Rename all (jpg) files written as 3 number in 4 numbers.
Useful if you have a list of images called 1 2 3 4 and so on, you can adapt it to rewrite it as 4 (in this example) 0-padded number.

Get the current svn branch/tag (Good for PS1/PROMPT_COMMAND cases)
uses just one sed

Find Out My Linux Distribution Name and Version
Another way of do it in debian like distros, don't know if works for others

Look up a unicode character by name
No need for further filedes or substitution for splitting. Simply use read a b

Sort output by length of line
This provides a way to sort output based on the length of the line, so that shorter lines appear before longer lines. It's an addon to the sort that I've wanted for years, sometimes it's very useful. Taken from my http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html

Count Files in a Directory with Wildcards.
Remove the '-maxdepth 1' option if you want to count in directories as well

Send an email from the terminal when job finishes
Might as well include the status code it exited with so you know right away if it failed or not.

Re-emerge all ebuilds with missing files (Gentoo Linux)
Revised approach to and3k's version, using pipes and read rather than command substitution. This does not require fiddling with IFS when paths have whitespace, and does not risk hitting command-line size limits. It's less verbose on the missing files, but it stops iterating at the first file that's missing, so it should be definitely faster. I expanded all the qlist options to be more self-describing.
