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"

A command's package details
In Debian based distros, this command will list 'binutils' package details which contains 'nm' command. You can replace 'nm' to any other command.

Backup your OpenWRT config (only the config, not the whole system)
You only have to fill in your administrative account and password, and the router FQDN! I recommand to execute this command not over the internet, because there is no encryption (the username and password will be transmitted in plaintext!)

locate bin, src, and man file for a command

Use wget to download one page and all it's requisites for offline viewing

Print all lines between two line numbers
This command uses awk(1) to print all lines between two known line numbers in a file. Useful for seeing output in a log file, where the line numbers are known. The above command will print all lines between, and including, lines 3 and 6.

Unlock more space form your hard drive
This command changes the reserved space for privileged process on '/dev/sda' to 1 per cent.

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

Create a git alias that will pull and fast-forward the current branch if there are no conflicts
This command will first add an alias known only to git, which will allow you to pull a remote and first-forward the current branch. However, if the remote/branch and your branch have diverged, it will stop before actually trying to merge the two, so you can back out the changes. http://www.kernel.org/pub/software/scm/git/docs/git-pull.html Tested on git 1.5.6.1, msysgit (Windows port) Actually this is not really the way I want it. I want it to attempt a fast-foward, but not attempt to merge or change my working copy. Unfortunately git pull doesn't have that functionality (yet?).

Stay in the loop…

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
