The newgrp command

[Vidol Loeung]

Thank you Ben and Richard for yoru replies.

Well, Ben you are right, root can switch to any group without having to give
a password. I also discovered the same as what Richard said. However, in
case an ordinary user is not a member of a particular group and she/he tries
to use the newgrp command to switch to that group with correct password, it
always gave the error message: Permission denied.

Read a lot of docs on it but still could not help.

Regards,
Vidol
