Unix – Make Directory Tree in a Swipe

If I wanted to created a directory tree say /first/second/third this is how I used to do it, till now.

$ cd /
$ mkdir first
$ cd first
$ mkdir second
$ cd second
$ mkdir third
$ cd third

Today I learnt that you could do this in a single swipe using the -p option!

mkdir -p first/second/third

And its not just restricted to simple hierarchies, you could even create a complex tree structure like this

$ mkdir -p project/{lib/ext,bin,src,doc/{html,info,pdf},demo/stat/a}
