i am trying to write a scrpt (eg : me.sh) and pass arguments to it so that if it is executed on the command prompt "me.sh -g" i should get the groupid of the user who has issued this
command. Similarly if some one issues "me.sh -u" i should get the userid.
You don't need an explicit exit. The exit code will be set automatically depending on the status of the scripts exit ('0' for success, non-zero otherwise). You can check the scripts exit status with "echo $#"
Finally, you have:
fi fi fi
which is not correct syntax.
I would help you more specifically but I suspect this is homework
Yes i do need to know the GID and UID, but only if the user asks for either of them or both. For Example the script is called "me.sh" so the user should be able to pass argument to this script, like this :-
"me.sh -g" to know the groupid or
"me.sh -u" to know the userid or
"me.sh -g -u" to know both.
