Changing file ownership (cont)

You can change user who owns a file if

You are root.

You are on a very dumb Unix-like OS that allows file giveaways by default[1].

 # id
 uid=0(root) gid=0(root) groups=0(root)
 # ls -l somefile
 -rw-rw-rw-  1 reegen web      0 Apr 19  2000 somefile

 $ chown bree:movies somefile; ls -l somefile
 -rw-rw-rw-  1 bree   movies   0 Apr 19  2000 somefile


[1] Can you say IRIX?
