I'm sorry, somehow I missed your earlier post.
Not sure what you mean by cutting of the "Shadow" file? The script looks at /etc/passwd and /etc/group not /etc/shadow :scratch:
I did find 2 problems with the script, I also added a --dry-run mode, which only prints out the commands that are going to be run without doing anything. Here is the updated version with changes in bold red:
Code:
#!/bin/bash
#
# delgroupmembers
# Shell script to delete all users in a specific group and delete the group.

exit 1

# Make sure we found a number
if [ $( echo $GROUPNUM | egrep -c ^[[:digit:]]+$ ) -eq 0 ]; then
echo "ERROR: Couldn't find group number for group $1"
exit 1
fi
# Find all users with this primary group according to /etc/passwd
USERLIST=$(egrep "^(.*):x:[[:digit:]]+:$GROUPNUM:.*:/home/$1/\1:.*$" $ETC/passwd | cut -f1 -d:)
# Then delete the users and group
if [ -z "$USERLIST" ]; then
echo "ERROR: There were no users found for group $1"
exit 1
fi
if [ $DRY_RUN = true ]; then
echo "DRY RUN MODE"
for user in $USERLIST ; do
echo "userdel -r $user"
echo "rm -r /home/$1/$user"
echo "smbpasswd -x $user"
done
echo "groupdel $1"
else
for user in $USERLIST ; do
userdel -r $user
rm -r /home/$1/$user
smbpasswd -x $user
done
groupdel $1
fi
If it still doesn't work post the output when you run bash -x /sbin/delgroup nhs2001 |
