Having difficulty changing group permissions

emerson1979 · 07-27-2013, 02:40 PM

Hello Everyone
I typed the following in terminal

dan@dan-MS-7369:~/Documents$ sudo chgrp wheel run.txt
chgrp: invalid group: `wheel'

I wished to change the group to wheel but was denied. Does anyone know the reason for this.

Thank

Did you check the /etc/passwd file to see if there is a 'wheel' group?

no I didn't. don't assume it's there. IF that's a requirement I 'm going to have to edit the file, something I have no experience at.

BTW to get a list of groups, look in /etc/group not /etc/passwd. You don't need to edit the password and group files by hand, groupadd and usermod will happily do the job for you.

Check out the man pages on the commands mentioned. They have a number of options and should get the job done for you.

Try

Code:
