group(5yp) group(5yp) Name group - group file in a Yellow Pages environment Description For each group, the file contains: Group name Encrypted password Numerical group ID Comma-separated list of all users allowed in the group This is an ASCII file. The fields are separated by colons. Each group is separated from the next by a new-line. If the password field is null, no password is needed. This file resides in the directory. Because of the encrypted passwords, it can and does have general read permission and can be used, for example, to map numerical group ID's to names. A group file can have a line beginning with a plus (+), which means to incorporate entries from the Yellow Pages. There are two styles of + entries: All by itself, + means to insert the entire contents of the Yellow Pages group file at that point; +name means to insert the entry (if any) for name from the Yellow Pages at that point. If a + entry has a password or group member field that is not null, the con- tents of that field will override what is contained in the Yellow Pages. The numerical group ID field cannot be overridden. Examples +myproject:::bill, steve +: If these entries appear at the end of a group file, then the group myproject will have members bill and steve, and the password and group ID of the Yellow Pages entry for the group myproject. All the groups listed in the Yellow Pages will be pulled in and placed after the entry for myproject. Restrictions The command will not change group passwords.
