param

helps to find parameter for bash scripting

syntax:

• 1st parameter: the parameter name to look for
• 2nd parameter: the default value if the parameter cannot be found
• all parameters from here: a parameter list to search through, where the value after a match to the first parameter is returned

example

Let's say we have this foo.sh bash script:

#!/usr/bin/env bash
EMAIL=$(param email [e-mail] "$@")
echo $EMAIL

now you can do:

./foo.sh
# outputs [e-mail] - the default

or

./foo.sh --email [e-mail]
# outputs [e-mail] - the parameter --email
