I am bit unclear of how Linux was set in the real world, please advise me how it's supposed to be.

When I log in as root and do a ls -l, I find: /boot, /, /var, /usr, /tmp, /home, /u01, /u02, /u03 and of of this partition is owned by root and the group also belong to root. Is that the way it's supposed to be??? or I should change /u01, /u02, /u03 to different owner beside root???

Please advise me what I should do.

Thanks so much everyone.

This is for HPUX, your results may vary...

All base level, root level, "directories" should be owned by root:sys or root:bin, in almost every case. There may be some exceptions to this.


However, for mounted filesystems, mine are owned by bin:bin.

It really depends on the OS. You need to go to the website for your flavor of UNIX and see what they recommend.
