No, you have it right - stat() stores only uid, and ls(1) does a name lookup for printing "the" (more precisely, "a") username associated with that id. >> Right, but in that case, the error message should make sense.

Not true - we still have two potential lookup problems. One is that that there may be NO name associated with ID (ls -l just falls back to listing id, but in the chmod case, we can't do a default login group lookup if we don't have a name). Try as root: # touch /tmp/f # chown 12345 /tmp/f # ls -l /tmp/f -rw-r--r--. 1 12345 root 0 Nov 21 13:51 /tmp/f The other is that even if a name is associated with an ID (whether the only name, or whether the first name out of multiple that map to the id), the default login group lookup for that name may fail (but that's true even if we didn't first do a uid->name lookup). Either way, my point remains - we should have a saner error message if we are unable to determine a default login group for a given user identification, rather than just declaring the entire '1001:' an invalid spec. --=20 Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org --E2jCeCB1lv3svGfkGs7P05erPOVVK3q7e Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.15 (GNU/Linux) Comment: Public key at http://people.redhat.com/eblake/eblake.gpg Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBCAAGBQJSjnLRAAoJEKeha0olJ0NqcJcH/idOUJjxVYLgG0oCXm6IGCq2 UUY64CuRtg8PAn8YUb2WC3kMV9TMq6s64t96wZRId2YRA6pEcNMwIyxFE+cbgR+p hLoVtCX4BbTMV68BwcgmEXw1sOGAUN7/B7tuyQvtp1Yqi8qw1kk7spyDblKmO/IF eJfGC/CyNZ1zUT06h0eIFGMA8UctXx2yRwPbbbhmy03BTGxQxm3rbLe2B39u/qy6 L40iXfrz0HkZXN5Vg4spvYL4x3oFmGU2BN4vu9d9vy53d+/5vGhp3Drkh3RQEMqP 4WNXqGGsDy7OVjFh4seDY2SQEhMv/YKA9240Ok1XWHqJcXKoGtWKJEqXKXyOnZY= =4aTj -----END PGP SIGNATURE----- --E2jCeCB1lv3svGfkGs7P05erPOVVK3q7e--

Interesting. But I guess the ID (for owner and group) is what is stored in the filesystem (as you can rename users and the ID stays the same on the file). In which case there is no tranlsation (ID -> name) necessary when calling chown with an uid. The "ls" then does the lookup to translate the ID in a name then. And so the ls could run into the mapping problem... or chown if called with a username. Or is it the other way round ? > Right, but in that case, the error message should make sense.

I think that anyone using this would expect it would take the first one returned. The same that happens right now in a "normal" system. The same name that 'ls -l' would return. We don't worry that 'ls -l' might be mapping a name that might not be unique and shouldn't here either. I realize that 'nscd' breaks that long standing assumption that order matters by returning one randomly. I consider that a bug in nscd. Bob

Long ago this was an existing behavior of GNU rm and discussion on the list talked of removing it. I defended it because I often used this on various systems to set the default group of a user. Because some systems are configured with user-private-groups where the user is in a private group while on other systems the user is in a shared "users" group. Using 'chown foo: file' was a nice way to set the group to foo's default group without needing to figure out what that group was ahead of time. I don't know when it was introduced into GNU chown but at the least I had been using it extensively. > so it looks like we have a bug that if OWNER is numeric, we aren't > looking up OWNER's login group.

Hehe.
I agree, two lines should be the only way to express that
there are 4 possibilities:
chown OWNER
chown OWNER:
chown OWNER:GROUP
chwon :GROUP
But shouldn't all 4 possibilities allow both OWNER and GROUP to be
specified either as NAME or as numerical ID ?
chown OWNERNAME == chown OWNERID [*]
chown OWNERNAME: == chown OWNERID: [**]
chown OWNERNAME:GROUPNAME == chown OWNERID:GROUPID[*]
chwon :GROUPNAME ==chown :GROUPID [*]
[*] working as expected
[**] NOT working as expected (see my bug report) ... but why ?
Especially as:
chown 1001:mine /tmp/bla
and
chown me:1001 /tmp/bla
works fine!
(with mine == 1001)

Ooh, you're right. We DO document that:
OWNER':'GROUP
If the OWNER is followed by a colon and a GROUP (a group name or
numeric group ID), with no spaces between them, the group ownership
of the files is changed as well (to GROUP).
OWNER':'
If a colon but no group name follows OWNER, that user is made the
owner of the files and the group of the files is changed to OWNER's
login group.
so it looks like we have a bug that if OWNER is numeric, we aren't
looking up OWNER's login group.
Which means my earlier comments aren't quite correct - the existing use
of [:[GROUP]] in usage text is correct. But I _still_ think we need to
split into two lines to make it obvious that the argument itself is
mandatory, as in:
Usage: chown [OPTION]... OWNER[:[GROUP]] FILE...
or: chown [OPTION]... :[GROUP] FILE...
or even rewrite it along the lines of the info page:
Usage: chown [OPTION]... NEWSPEC FILE...
and document that NEWSPEC is [OWNER][:[GROUP]]

Hi again,
Sorry, I don't know why, but I missed this part of your answer:
On 21/11/13 16:53, Eric Blake wrote:

But I want the same effect than
chown me: /tmp/bla
so changing:
(1) the owner of /tmp/bla to user "me"
(2) the group of /tmp/bla to the login-group of user "me"
chown me /tmp/bla
should only do (1), no ?

Yes, but when you execute:
chown me: /tmp/bla
as group is '' as well and it is not a problem.
I don't see any problem / ambiguity in allowing both:
chown me: /tmp/bla
chown 1001: /tmp/bla
especially as:
chown me /tmp/bla
chown 1001 /tmp/bla
are both possible and provide the same result.
So for the trailing ":" case it should be (flexibly/convieniently) work
the same, no ?

Dear GNU team,
But why is not possible for "chown 1001: /tmp/bla"
to resolve 1001 to "me"
and then do the same than "chown me: /tmp/bla" ?
(I guess internally chown will do the reverse lookup (me -> 1001), when
performing a "chown me: /tmp/bla")
Could you please be so kind to explain the "why not" ?
==============================================
Wording in "man chown":
DESCRIPTION
This manual page documents the GNU version of chown. chown
changes the
user and/or group ownership of each given file. If only an
owner (a
user name or numeric user ID) is given, that user is made the
owner of
each given file, and the files' group is not changed. [1] If the
owner is
followed by a colon and a group name (or numeric group ID),
with no
spaces between them, the group ownership of the files is
changed as
well. [2] If a colon but no group name follows the user name,
that user is
made the owner of the files and the group of the files is
changed to
that user's login group. If the colon and group are given,
but the
owner is omitted, only the group of the files is changed; in this
case,
chown performs the same function as chgrp. If only a colon is
given,
or if the entire operand is empty, neither the owner nor the
group is
changed.
[1] At this point "owner" is referenced as "name or numeric ID".
[2] At this point you do not reprecise "owner" but only state about the
additional colon ":" -- so one must expect "owner" still to be "name or
numeric ID".
Best,
Tormen

Per 'chown= > --help', the syntax is: > chown [OPTION]... [OWNER][:[GROUP]] FILE... Hmm, on re-reading this, I think we have two bugs in our help syntax. The major bug is that we document [GROUP] as optional, but in reality it is mandatory if ':' is present. So we definitely need to change '[:[GROUP]]' to '[:GROUP]'. The minor group stems from a GNU extension. POSIX requires that the OWNER portion is mandatory: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/chown.html But as a GNU extension, we allow it to be empty to allow for: > chown :1001 /tmp/bla # change group only But as written, the usage text implies that we can omit both OWNER and :GROUP and still have a valid call, as in: chown /tmp/bla which isn't quite true. Alas, the only way I can see to rewrite the fact that SOME spec is necessary, while still highlighting the GNU extension of omitting OWNER, is to split the usage into two lines: Usage: chown [OPTION]... OWNER[:[GROUP]] FILE... or: chown [OPTION]... :GROUP FILE... Thoughts?
