Handy shell commands

Dealing with broken things always tends to further my knowledge. Recently I discovered the following tips and tricks:

ls -d */ = Lists directories in the current directory.
disown = Disconnects a process fomr the bash session ready for logout if you have not already redirected the output.
nohup = Starts a process backgrounded and writing to nohup.out.
mkdir -p = Makes a directory and makes the parent directories if missing.
