Simulate typing
This will output the characters at 10 per second.

run php code inline from the command line
Most people know that you can run a PHP script from the command line like so: $php ./my_script.php But sometimes I just want to run a quick bit of code, the PHP Command Line Interface allows me to do so with the -r option. Requires package php5-cli

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"

watch the previous command
If you just executed some long command, like "ps -aefww | grep -i [m]yProcess", and if you don't want to retype it or cycle backwards in history and waste time quoting it, then you can use history substitution.

Get your external IP address
Request all information about my IP address in json format

Forward port 8888 to remote machine for SOCKS Proxy
Simply change your web browser's proxy settings to point to a SOCKS proxy at port 8888 and you're good to go.

Dump bash command history of an active shell user.

Show a curses based menu selector
Not so much handy by itself, but very nice in shell scripts. This makes you a handy ncurses based checklist. Much like terminal installers, just use the arrow keys and hit 'Space' to adjust the selections. Returns all selected tags as strings, with no newline at the end. So, your output will be something like: "one" "two" "three" "four" "etc" For those who prefer bash expansion over gratuitious typing: $ whiptail --checklist "Simple checkbox menu" 12 35 3 $(echo {one,two,three,four}" '' 0"} ) Things to note: The height must includes the outer border and padding: add 7 to however many items you want to show up at the same time. If the status is 1, it will be selected by default. anything else, will be deselected.

Remove audio stream from a media file
This syntax also works for ffmpeg as avconv is a fork of ffmpeg.
