bash script

Occasionally I need to write bash scripts and just wanted to jot down some notes that are helpful when doing that.

The first line of the script should read

 #!/bin/bash

And then you can check the number of command line arguments that are passed into the script with

$#

and then the arguments can be accessed by using

$1 or $2, etc.

and the name of the script can be accessed with

$0

and finally, all the command line arguments can be accessed with

$@
