hi

is it possible to change the group of system user
like /sbin/shutdown .

can i do it with usermod ,

what happens if i change the group info in /etc/passwd
will it make the program not execute...

(*i dont want to change the owner but only the group)

thx in advance

Not sure I follow...

Do you mean that you have a user (ted) that belongs in a group (sales) and you want to remove that user from that group?
usermod -G sales ted

OR, do you mean that you have a group (superusers) that the user belongs to that you want to give the group permissions on a service, but not limit it to just a user:
chgrp superusers /sbin/shutdown

Could you clarify what you want so we/I can give you a more appropriate answer?

Cool

Why do u want to do that, unless and untill its specifically required dont change the system default user & group permissions.

nope what i meant was when i checked /etc/passwd i saw a userid (6) for shutdown on my rh9 , and it belonged to the group root .

now i wanted to know whether to change the group of shutdown to someother group ...
