Description Ralph Loader 2006-07-15 20:36:27 EDT
Description of problem:

chown can give a misleading and irrelevant error message if a non-existant user
id is given.

Version-Release number of selected component (if applicable):

coreutils-5.97-4

How reproducible:

Everytime.

Steps to Reproduce:
1.

# chown sapoqwegfj /dev/ttyS1 
chown: `sapoqwegfj': invalid user

2.

~# chown sapoqwegfj: /dev/ttyS1 
chown: `sapoqwegfj:': cannot get the login group of a numeric UID
  
Actual results:

The second error message "cannot get the login group of a numeric UID" does not
indicate the actual problem.

Expected results:

The second error message be identical to the first, or at least should indicate
that the given user name does not exist.

Thanks for the report.
I've just fixed this upstream.  Here's the ChangeLog entry:

* userspec.c (parse_with_separator): Say "invalid spec" rather than
the sometimes erroneous "cannot get the login group of a numeric UID"
for a spec like "not-a-username:" or "1:".  Reported by
