I'm trying to change the ownership of a file that I as user oracle own to
user u55646 the following occurs
-rw-r--r--1 u55646 dba 583 2003-09-18 13:01 rfc1953.log
-rw-rw-rw-1 oracle oinstall 418 2003-09-18 12:55 rfc1953.sql
-rw-r--r--1 oracle oinstall 583
You need to be root to do that. One user cannot change file ownerships to
another user.

Short version: Linux does not allow non-privileged use of chown. You have
to be root to do it.
Longer version:
Actually Linux supports capabilities. You can give the capability to use
OK, scratch that... I tried it your way and the period is accepted.

A period works just as well (I use it all the time out of habit). He's not
getting a syntax error, it's permissions related.

Why ? The systems which allow the non-privileged use of chown drops the
setgid and setuid bits when changing the owner.

Do all of them? Because, yes, that's the hole I was thinking of.

yuck. coming from HP-UX, it allows you to give a file to another
owner.
So install sudo and give those users the right to use chown without any
password. Adding something like alias chown='sudo chown'. Linux drops
the setuid and setgid bits when changing ownership.

I would not bet on the all. It is too easy to get bitten by that one :)
But iirc POSIX requires that for unprivileged use. (there is no standard
for privileged use).

Dans un message du 18 sep ` 16:24, Alex deVries icrivait :
I suppose if you really didn't like this behaviour, you could write
your own setuid version of chown.
It is best way to open an huge security hole. It is better to use sudo.
