Arguments in bash script

The arguments are stored in variables with a number in the order of the argument starting at 1

• First Argument: $1
• Second Argument: $2
• Third Argument: $3

Example:

./script.bash alpha beta gamma

Variables are: $1=='alpha', $2=='beta' and $3=='gamma'

The variable $0 is the script name. The total number of arguments is stored in $#. The variables $@ (array) and $* (string) return all the arguments.
