getopts question
could anyone please tell me what this will automatically set my variable all=True....
Code:
#!/bin/sh
all=FALSE
while getopts a: option
do
case "option"
in
a) all=TRUE;;
/?) echo "...... "
exit 1;;
esac
done
if [ "$all"=TRUE ]
then
echo "true"
else
echo "false"
fi
if i do $ foo ls (without the -a) it will still echo true.... why???? thanks if possible, please explain when I need to do something like: while getopts a: option (do i need the colon ? ) and what is the difference between $# and $OPTIND ? |
