Easily decode unix-time (funtion)
A shell function using perl to easily convert Unix-time to text. Put in in your ~/.bashrc or equivalent. Tested on Linux / Solaris Bourne, bash and zsh. using perl 5.6 and higher. (Does not require GNU date like some other commands)

check open ports without netstat or lsof

clone a hard drive to a remote directory via ssh tunnel, and compressing the image

Ping all hosts on 192.168.1.0/24

move you up one directory quickly
In bash, this turns on auto cd. If a command is just a directory name, it cd's into that directory.

ls -qaltr # list directory in chronological order, most recent files at end of list
I find it very handy to be able to quickly see the most recently modified/created files in a directory. Note that the "q" option will reveal any files with non-printable characters in their filename.

Display top 5 processes consuming CPU

Quick searching with less
This command enables the user to append a search pattern on the command line when using less as the PAGER. This is especially convenient (as the example shows) in compressed files and when searching man pages (substituting the zcat command with man, however).
