NAME

7       groups

SYNOPSIS

10       systemd-sysusers [OPTIONS...] [CONFIGFILE...]
11
12       systemd-sysusers.service
13

DESCRIPTION

15       systemd-sysusers creates system users and groups, based on the file
16       format and location specified in sysusers.d(5).
17
18       If invoked with no arguments, it applies all directives from all files
19       found in the directories specified by sysusers.d(5). When invoked with
20       positional arguments, if option --replace=PATH is specified, arguments
21       specified on the command line are used instead of the configuration
22       file PATH. Otherwise, just the configuration specified by the command
23       line arguments is executed. The string "-" may be specified instead of
24       a filename to instruct systemd-sysusers to read the configuration from
25       standard input. If only the basename of a file is specified, all
26       configuration directories are searched for a matching file and the file
27       found that has the highest priority is executed.
28

OPTIONS

30       The following options are understood:
31
32       --root=root
33           Takes a directory path as an argument. All paths will be prefixed
34           with the given alternate root path, including config search paths.
35
36       --replace=PATH
37           When this option is given, one ore more positional arguments must
38           be specified. All configuration files found in the directories
39           listed in sysusers.d(5) will be read, and the configuration given
40           on the command line will be handled instead of and with the same
41           priority as the configuration file PATH.
42
43           This option is intended to be used when package installation
44           scripts are running and files belonging to that package are not yet
45           available on disk, so their contents must be given on the command
46           line, but the admin configuration might already exist and should be
47           given higher priority.
48
49           Example 1. RPM installation script for radvd
50
51               echo 'u radvd - "radvd daemon"' | \
52                         systemd-sysusers --replace=/usr/lib/sysusers.d/radvd.conf -
53
54           This will create the radvd user as if
55           /usr/lib/sysusers.d/radvd.conf was already on disk. An admin might
56           override the configuration specified on the command line by placing
57           /etc/sysusers.d/radvd.conf or even
58           /etc/sysusers.d/00-overrides.conf.
59
60           Note that this is the expanded form, and when used in a package,
61           this would be written using a macro with "radvd" and a file
62           containing the configuration line as arguments.
63
64       --inline
65           Treat each positional argument as a separate configuration line
66           instead of a file name.
67
68       --cat-config
69           Copy the contents of config files to standard output. Before each
70           file, the filename is printed as a comment.
71
72       --no-pager
73           Do not pipe output into a pager.
74
75       -h, --help
76           Print a short help text and exit.
77
78       --version
79           Print a short version string and exit.
80

EXIT STATUS

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