SYNOPSIS
systemctl help PATTERN...|PID...
DESCRIPTION
systemctl help displays the manual pages for one or more units. If a numeric PID is provided instead of a unit name, it shows the manual for the unit that process belongs to.
The manual page is determined by the `Documentation=` directive in the unit file.
PARAMETERS
--user
Show help for user units--no-pager
Display all output at once without paging
CAVEATS
Not all units have associated documentation. The Documentation= directive must be set in the unit file for this to work. Falls back to generic systemd documentation if no specific manual exists.
HISTORY
The help subcommand provides integrated documentation access directly from the unit management interface, linking units to their relevant manual pages.
