lgroupmod

lgroupmod(8)						      System Manager's Manual						      lgroupmod(8)

NAME

       lgroupmod - Modify an user group

SYNOPSIS

       lgroupmod [OPTION]... group

DESCRIPTION

       Modifies the user group with name group.

OPTIONS

       -A, --admin-add=list
	      Add users in comma-separated list among group's administrators.

       -a, --admin-remove=list
	      Remove  users  in comma-separated list from group's administrators.  Removing users that are not currently among group's administra-
	      tors silently succeeds.

       -g, --gid=gid
	      Change group's group ID to gid.

       -i, --interactive
	      Ask all questions when connecting to the user database, even if default answers are set up in libuser configuration.

       -L, --lock
	      Lock group.  This prevents users from using the group password with newgrp(1) to become a member of group.

       -M, --member-add=list
	      Add users in comma-separated list among group's members.

       -m, --member-remove=list
	      Remove users in comma-separated list from group's members.  Removing users that are not currently  among	group's  members  silently
	      succeeds.

       -n, --name=name
	      Rename group to name.

       -P, --plainpassword=password
	      Set group's password to password.  Note that the password can be viewed while running lgroupmod using tools such as ps(1).

       -p, --password=encrypted
	      Set  group's  password  to the password represented by the hash encrypted.  Note that the hash can be viewed while running lgroupmod
	      using tools such as ps(1).

       -U, --unlock
	      Unlock group.

EXIT STATUS

       The exit status is 0 on success, nonzero on error.
