Here’s a short type to handle arguments given like this to a bash script :

./my_script -arg value

First, we test if an argument has been given :

if [ $# -eq 0 ]; then 
	

		
no args, we echo a short help message and exit

echo -e “usage : ./my_script -arg [value|other_value]”

exit 1

fi

After, here’s the code which is going to handle the argument and its value :

if [ ”$1” = ”-arg” ]; then

shift;#we shift to the value, now $1 is the string given after -arg

case ”$1” in

“value”) echo -e ” here we do something with the value value” ;;

“other_value”) echo -e ” here we do something with the value other_value”;;
	

		
echo -e “default case, maybe value is missing or is not wanted value” ;;

esac
