ssh autocomplete
Autocomplete from .ssh/config

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"

!* Tells that you want all of the *arguments* from the previous command to be repeated in the current command
Example: touch file{1,2,3}; chmod 777 !*

Decode base64-encoded file in one line of Perl
Another option is openssl.

Do Google search from that command line opening into a new Firefox tab.
Usage: google "[search string]" Example: google "something im searching for" This will launch firefox and execute a google search in a new tab with the provided search string. You must provide the path to your Firefox binary if using cygwin to $ff or create an alias like follows: alias firefox='/cygdrive/c/Program Files (x86)/Mozilla Firefox/firefox.exe' Most Linux flavors with Firefox installed will use just ff="firefox" and even OSX.

Router discovery

Resolution of a image
You can use the -format switch to get the size of the image. Replace "logo:" with your image.

Remove newlines from output
Remove newlines from output. One character shorter than awk /./ filename and doesn't use a superfluous cat. To be fair though, I'm pretty sure fraktil was thinking being able to nuke newlines from any command is much more useful than just from one file.

Check reverse DNS
The +short option should make dig less chatty.
