Avoid killing the X server with CTRL+C on the tty it was started from

Testing php configuration
Run the function phpinfo() on the shell

urldecoding with one pure BASH builtin
You can use ordinary printf to convert "%23%21%2fbin%2fbash" into "#!/bin/bash" with no external utilities, by using a little known printf feature -- the "%b" specifier converts shell escapes. Replace % with \x and printf will understand the urlencoded string. BASH's printf has an extension to set a variable directly, too. So you get to convert urlencoded strings from garble to plaintext in one step with no externals and no backticks.

Rename files in batch

Create a new file

execute a shell with netcat without -e
Shorter version with proper stderr redirection .

Run the last command as root
Same as `sudo !!`. If you do not have permission to be sudo or sudo does not installed on your system, you can use this.

Find
A lot of X applications accept --geometry parameter so that you can set application size and position. But how can you figure out the exact arguments for --geometry? Launch an application, resize and reposition its window as needed, then launch xwininfo in a terminal an click on the application window. You will see some useful window info including its geometry.

Suppress output of loud commands you don't want to hear from
Suppresses all output to /dev/null. This could be expanded to check for a -l command line option to log the stderr to a file maybe -l file or -l to log to default quietly.log. I'm finding that I use it more often than one would think.
