Salvage a borked terminal
Also works in places where reset does not.

Show apps that use internet connection at the moment. (Multi-Language)
Show apps that use internet connection at the moment. Can be used to discover what programms create internet traffic. Skip the part after awk to get more details, though it will not work showing only unique processes. This version will work with other languages such as Spanish and Portuguese, if the word for "ESTABLISHED" still contain the fragment "STAB"(e.g. "ESTABELECIDO")

move contents of the current directory to the parent directory, then remove current directory.
Robust means of moving all files up by a directory. Will handle dot files, filenames containing spaces, and filenames with almost any printable characters. Will not handle filenames containing a single-quote (but if you are moving those, it's time to go yell at whoever created them in the first place).

Extract the contents of an RPM package to your current directory without installing them.
This assumes you have the 'rpm', 'rpm2cpio' and 'cpio' packages installed. This will extract the contents of the RPM package to your current directory. This is useful for working with the files that the package provides without installing the package on your system. Might be useful to create a temporary directory to hold the packages before running the extraction: $ mkdir /tmp/new-package/; cd /tmp/new-package

Create a new file

Link a deep tree of files all into on directory
If you want to pull all of the files from a tree that has mixed files and directories containing files, this will link them all into a single directory. Beware of filesystem files-per-directory limits.

get you public ip address

Inverted cowsay
It's quite fun to invert text using "flip.pl" (ref: http://ubuntuforums.org/showthread.php?t=2078323 ). Slightly more challenging is to flip a whole "cowsay". :-)

remove empty lines in place with backup
Modify file in place to remove empty lines and create a backup of the original with the extension .bak
