Full Discussion: Append users if GID exists

It sounds like you could egrep or sed or awk or bash a list as it downloads, just keeping what you want for a list of users.

$Variables are not evaluated inside single quotes (not much is, so I prefer them, generally).

No point in going through the file twice, with sed and grep.

Red hat exact identity is in /etc/*red*hat* !

group

GROUP(5)                                                     Linux Programmer's Manual                                                    GROUP(5)

NAME

       group - user group file

DESCRIPTION

       The /etc/group file is a text file that defines the groups on the system.  There is one entry per line, with the following format:

           group_name:password:GID:user_list

       The fields are as follows:

       group_name  the name of the group.

       password    the (encrypted) group password.  If this field is empty, no password is needed.

       GID         the numeric group ID.

       user_list   a list of the usernames that are members of this group, separated by commas.

FILES

       /etc/group

BUGS

       As the 4.2BSD initgroups(3) man page says: no one seems to keep /etc/group up-to-date.
