Hi,

This looks like homework, which we will not do for you. We are willing to help though.

What have you tried and what did or did not work?

Hints: Use a loop to read the user names and have a look at the id command.

Hope this helps.

It's your job, intended to train you (not us), so what have you tried so far?

Hi,

Have a look at this:
Code:
while read NAME; do echo -n "${NAME} : " ; id -nG ${NAME}; done < infile
Or as full script:
Code:
#!/bin/bash

while read NAME
do
  echo -n "${NAME} : "
  id -nG ${NAME}
done < infile
I leave it up to you to figure out how this works, that way you'll actually learn something.

Hope this helps.

Hi,

If you use a while loop (see post #5) you don't need the export user=`cat groups.sh.....` part.

Hope this helps.
