• How to use functions in bash

• Here an example: you can pass values returned by programms as parameter to check them.

#Functions======================================
function check() {
	FC=$1
	if [ $FC != "0" ];then
           echo -e "--> ERROR\n"
	else
	   echo -e "--> OK\n"
	fi
	}
#============================================

• You can use the function by its name with parameter (here an exit code) e.g.: check “$?”
