Check These Out

Display the top 10 running processes - sorted by memory usage
A pretty nice display of processes.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

list block devices
Shows all block devices in a tree with descruptions of what they are.

Copy structure
Copies a dir structure without the files in it.

Add your public SSH key to a server in one command
Just run the command, type your password, and that's the last time you need to enter your password for that server. This assumes that the server supports publickey authentication. Also, the permissions on your home dir are 755, and the permissions on your .ssh dir are 700 (local and remote).

find external links in all html files in a directory list
Just a handy way to get all the unique links from inside all the html files inside a directory. Can be handy on scripts etc.

Compress excutable files in place.
The gzexe utility allows you to compress executables in place and have them automatically uncompress and execute when you run them. FYI: You can compress any executable sha-bang scripts as well (py, pl, sh, tcl, etc.).

Decode base64-encoded file in one line of Perl
If you are in an environment where you don't have the base64 executable or MIME tools available, this can be very handy for salvaging email attachments when the headers are mangled but the encoded document itself is intact.

Show current pathname in title of terminal
This helps to keep track of what is going on when you have several tabs open in your terminal. The title automatically changes when you change directories.

Find and copy files from subdirectories to the current directory
