Ok, I made little modification because if you were looking for a group id,
say 10, and a person's group id was 100 it would include them (I just added
the -w option after the first grep). Now, how can I make it so it doesn't
include a user who's userid is the same as the groupid I am looking for ?
Here is the code I have now:
#!/bin/sh
TMP=`mktemp /tmp/group.XXXXXX`
grep -w `grep "^${1}:" /etc/group | cut -d: -f3` /etc/passwd | cut -d: -f1
> $TMP
grep "^${1}:" /etc/group | cut -d: -f4 | sed 's/,/\
/g' >> $TMP
cat $TMP | uniq
rm -f $TMP
-Bill
