Debian vs Mac OS X regarding the
On Mac OS X, in order to make a file accessible to only the owner and the administrators, I set the group of the file to
admin, and set the permission mode of the file to something like 770 (rwxrwx---), 750 (rwxr-x---) or 640 (rw-r-----).
chgrp admin FILE chmod 750 FILE # or chmod 770 FILE # or chmod 640 FILE # or chmod g+r,o-rwx FILE
ls -la FILE outputs something like the following, where bob is the owner.
rwxr-x--- bob admin
However, Debian lacks the
admin group. What is the Debian counterpart of the
admin group? What group on Debian makes files accessible to only the owner and the administrators (after chmod has removed rwx from others)?
By the command
id -Gn, administrators on Mac OS X seem to belong to the
admin group, while administrators on Debian seem to belong to the
sudo group. Is the
sudo group on Debian equivalent to the
admin group on Mac OS X?
I hesitate to set the group of the file to
sudo. The command
find / -group sudo reveals that absolutely no files on Debian have the group
sudo by default. In contrast, the command
find / -group admin reveals that many files on Mac OS X have the group
admin by default. So, it seems that the
sudo group on Debian is not really equivalent to the
admin group on Mac OS X.
