NAME

       systemd-sysusers, systemd-sysusers.service - Allocate system users and groups

SYNOPSIS

       systemd-sysusers [OPTIONS...] [CONFIGFILE...]

       systemd-sysusers.service

DESCRIPTION

       systemd-sysusers creates system users and groups, based on the file format and location
       specified in sysusers.d(5).

       If invoked with no arguments, it applies all directives from all files found in the
       directories specified by sysusers.d(5). When invoked with positional arguments, if option
       --replace=PATH is specified, arguments specified on the command line are used instead of
       the configuration file PATH. Otherwise, just the configuration specified by the command
       line arguments is executed. The string "-" may be specified instead of a filename to
       instruct systemd-sysusers to read the configuration from standard input. If only the
       basename of a file is specified, all configuration directories are searched for a matching
       file and the file found that has the highest priority is executed.

OPTIONS

       The following options are understood:

       --root=root
           Takes a directory path as an argument. All paths will be prefixed with the given
           alternate root path, including config search paths.

       --replace=PATH
           When this option is given, one ore more positional arguments must be specified. All
           configuration files found in the directories listed in sysusers.d(5) will be read, and
           the configuration given on the command line will be handled instead of and with the
           same priority as the configuration file PATH.

           This option is intended to be used when package installation scripts are running and
           files belonging to that package are not yet available on disk, so their contents must
           be given on the command line, but the admin configuration might already exist and
           should be given higher priority.

           Example 1. RPM installation script for radvd

               echo 'u radvd - "radvd daemon"' | \
                         systemd-sysusers --replace=/usr/lib/sysusers.d/radvd.conf -

           This will create the radvd user as if /usr/lib/sysusers.d/radvd.conf was already on
           disk. An admin might override the configuration specified on the command line by
           placing /etc/sysusers.d/radvd.conf or even /etc/sysusers.d/00-overrides.conf.

           Note that this is the expanded from, and when used in a package, this would be written
           using a macro with "radvd" and a file containing the configuration line as arguments.

       --inline
           Treat each positional argument as a separate configuration line instead of a file
           name.

       --cat-config
           Copy the contents of config files to standard output. Before each file, the filename
           is printed as a comment.

       --no-pager
           Do not pipe output into a pager.

       -h, --help
           Print a short help text and exit.

       --version
           Print a short version string and exit.

EXIT STATUS

       On success, 0 is returned, a non-zero failure code otherwise.
