GROUPMOD(8)

NAME
groupmod - Modify a group

SYNOPSIS
groupmod [-g gid [-o]] [-n group_name ] group

DESCRIPTION
The groupmod command modifies the system account files to reflect the changes that are specified on the command line. The options which apply to the groupmod command are

-g gid
    The numerical value of the group's ID. This value must be unique, unless the -o option is used. The value must be non-negative. Values between 0 and 999 are typically reserved for system groups. Any files which the old group ID is the file group ID must have the file group ID changed manually.

-n group_name
    The name of the group will be changed from group to group_name.

FILES
/etc/group    - group information
/etc/gshadow    - secure group information

    0 - success
