Top Forums UNIX for Advanced & Expert Users is it possible to have a 1000 user in single group Post 302257832 by methyl on Thursday 13th of November 2008 06:58:38 AM

There is no limit on the number of users in a primary group. The limit of LINE_MAX applies to each secondary group. It is not necessary or advisible to list any users primary group in /etc/group .
Though not tried on Red Hat, I have seen multiple lines for the same group in /etc/group in a very large unix SVR4 system.

NAME
groupdel - delete a group SYNOPSIS
groupdel [options] GROUP DESCRIPTION
The groupdel command modifies the system account files, deleting all entries that refer to GROUP. The named group must exist. OPTIONS
The options which apply to the groupdel command are: -h, --help Display help message and exit. -R, --root CHROOT_DIR Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory. CAVEATS
You may not remove the primary group of any existing user. You must remove the user before you remove the group. You should manually check all file systems to ensure that no files remain owned by this group. CONFIGURATION
The following configuration variables in /etc/login.defs change the behavior of this tool: MAX_MEMBERS_PER_GROUP (number) Maximum members per group entry. When the maximum is reached, a new group entry (line) is started in /etc/group (with the same name, same password, and same GID). The default value is 0, meaning that there are no limits in the number of members in a group. This feature (split group) permits to limit the length of lines in the group file. This is useful to make sure that lines for NIS groups are not larger than 1024 characters. If you need to enforce such limit, you can use 25. Note: split groups may not be supported by all tools (even in the Shadow toolsuite). You should not use this variable unless you really need it. FILES
/etc/group Group account information. /etc/gshadow Secure group account information. EXIT VALUES
The groupdel command exits with the following values: 0 success 2 invalid command syntax 6 specified group doesn't exist 8 can't remove user's primary group 10 can't update group file SEE ALSO
