Add prefix onto filenames
Best to try first with -n flag, to preview

Install an mpkg from the command line on OSX
Installing most OSX apps is just a matter of dropping it in /Applications, either GUI-wise or with cp -r. However, many packages are distributed in "mpkg" format, and those have to be installed with an installer. If you don't want to go to the trouble of firing up VNC to install an mpkg, you can use the "installer" command. This will install an application from a .mpkg it to /Applications system-wide. To install a program for just one user, replace "-target /" with "-target username".

Remove color codes (special characters) with sed

RTFM function
Sometimes you don't have man pages only '-h' or '--help'.

check open ports without netstat or lsof

Clean up after a poorly-formed tar file
These days, most software distributed in tar files will just contain a directory at the top level, but some tar files don't have this and can leave you with a mess of files in the current folder if you blindly execute $ tar zxvf something.tar.gz This command can help you clean up after such a mistake. However, note that this has the potential to do bad things if someone has been *really* nasty with filenames.

find an unused unprivileged TCP port
Not really better - just different ;) There's probably a really simple solution out there somewhere...
