Check These Out

count how many times a string appears in a (source code) tree
grep -o puts each occurrence in a separate line

Simple way to envoke a secure vnc session through ssh enabled router.
The ip address is of the remote machine running the vncserver. Must log in first to the router then the VNC session. Very nice if you have open-wrt or dd-wrt on your router.

Clear terminal Screen
Probably the quickest / easiest way to clear the screen.

Manipulate the metadata and edit the create time (This will change date to 1986:11:05 12:00 - Date: 1986 5th November, Time: 12.00) and then it will set modify date to the same as alldate.

list files recursively by size

Make any command read line enabled (on *nix)
Enable readline even if the command line application is not using it.

shuffle lines via perl
Same, without modules... Probably smarter option: just use the shuf command or even sort -R.

Install pip with Proxy
Installs pip packages defining a proxy

Update all outdated Python packages through pip.

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.
