systemd-sysusers

Create system users and groups. If the config file is not specified, files in the sysusers.d directories are used. More information: https://www.freedesktop.org/software/systemd/man/systemd-sysusers.html.

• Create users and groups from a specific configuration file:

systemd-sysusers {{path/to/file}}

• Process configuration files and print what would be done without actually doing anything:

systemd-sysusers --dry-run {{path/to/file}}

• Print the contents of all configuration files (before each file, its name is printed as a comment):

systemd-sysusers --cat-config

• Create users based on files listed in the previous command:

systemd-sysusers
