That would explain the differences. Using groups(1) (which is a shell script that calls id(1)) or id(1) with a user argument reads the group(5) file whereas using id(1) with no arguments tells you what the system believes your group membership in the current session to be. This would make sense if you did something like, 1. Log in as buki 2. su(1) to root 3. Make group changes for buki 4. Exit root shell 5. Run the above group(1) and id(1) commands You need to add, 6. Log out from buki's session 7. Log is as buki 8. Run the above group(1) and id(1) commands And see what happens. -- Crist J.
