BASH: Print shell variable into AWK
Alternatively: export MyVAR=84; awk '{ print ENVIRON["MyVAR"] }'

Backup file, create dir and set perms in one shot
Prior to working on/modifying a file, use the 'install -m' command which can both copy files, create directories, and set their permissions at the same time. Useful when you are working in the public_html folder and need to keep the cp'd file hidden.

Expand shortened URLs
This relies on a public API from http://longurl.org. So, this has the weakness that if the service disappears, the function will break. However, it has the advantage that the shortened URL service will not be tracking your IP address and other metrics, but instead will track longurl.org. Thus, you can remain anonymous from the shortened URL services (although not anonymous from longurl.org). It does no sanity checking that you have provided an argument. If you do not provide one, "message" is displayed to STDOUT.

Look for English words in /dev/urandom

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

Realtime lines per second in a log file
Using tail to follow and standard perl to count and print the lps when lines are written to the logfile.

List all users and groups

Show the UUID of a filesystem or partition
Show the UUID-based alternate device names of ZEVO-related partitions on Darwin/OS X. Adapted from the lines by dbrady at http://zevo.getgreenbytes.com/forum/viewtopic.php?p=700#p700 and following the disk device naming scheme at http://zevo.getgreenbytes.com/wiki/pmwiki.php?n=Site.DiskDeviceNames

Remove everything except that file
Remove everything except that file with shell tricks inside a subshell to avoid changes in the environment. $ help shopt

Minimize active window
Bind it to some shortcut key, using something like xbindkeys-config (if you do not have xbindkeys: apt-get install xbindkeys xbindkeys-config)
