Unix Shell Scripting, reading command options from the reader.?

Question

I am writing a command for users. When checking the options ( -f -i or -fi for example) I don't want to use a serious of if statements or a long case-switch program. Does anyone have any idea how to read these options in?

Answer 1

Are you looking for something like getopts for example:

-f -i

while getopts f:i opt
do
case "$opt" in
f) ;;
i) ;;
esac
done

Is that what you have in mind?

Answer 2

I am at the same quandry... Isn't there a module that shows us something here... perhaps on the C language forum/wiki?

I don't know too many yahooligans who even know what a command is, much less, how to obey one!

Answer 3

take the options as comand line and check for arg 0 arg1 arg2
