groupadd man page

[Keith Roberts]

Hi. This is on Fedora Core 6 platform.

> From the man page for:

System Management Commands  06/24/2006  GROUPADD(8)

Is this correct:

*snip*

CAVEATS
       Groupnames must begin with a lower case letter or an
       underscore, and only lower case letters, underscores,
       dashes, and dollar signs may follow. In regular expression
       terms:

       [a-z_][a-z0-9_-]*[$]

The description does not seem to match the regular expression.
There is no mention of integer digits in the description.

Is this what you mean for a regular expression, according to 
the above description?

   # must begin with a lower case letter or an underscore
   [a-z_]

   # and only lower case letters, underscores, dashes,
   # and dollar signs may follow
   [a-z_-$]*

Which would give the full regex of:
   [a-z_][a-z_-$]*


Or do you mean something like this, including the integer 
digits: [a-z_][a-z0-9_-$]*

       Groupnames may only be up to 16 characters long.
       (line repeated below)

       If the groupname already exists in an external group
       database such as NIS, groupadd will deny the group
       creation request.

       Groupnames may only be up to 16 characters long.

Kind Regards
