passwd

Indrajit Bhagat — Mon, 15 Sep 2008 08:59:59 GMT

We have default read-read-read permission on /etc/passwd.

# pwd
/etc
# ll passwd
-r--r--r-- 1 root sys 3234 Aug 13 19:48 passwd

Then how an individual user or root is able to change the passwd.

Because passwd(1) is setuid and root can do anything.

hi,
what you are asking is passwd(4), but passwd(1) is havind setuid, so root permissions will change the things for you.

root is the owner of the file , root is also an super user, so it can do any permissions.

Also any user is the owner of some file, it can set any permissions to that file.

Thanks
