question relate to "group"?

[mcclnx mcc]

We are migrated system from AIX to Redhat (AS 3).  I
have questions relate to "group".


  1. on AIX  user put on "bin" group can backup whole
server, how about LINUX?

2. On AIX user put on "printq" group can "cancel"
print job.  How about on LINUX?

3. any document mention about "group" privilege?


Thanks.
