How do i list systemd unit files by type?



  • Man page for systemd(1), init(1) - systemd system and service manager
    Man page for systemd.special(7) - Special systemd units

    $  systemctl list-unit-files --type=service
    

    You can also list units by type.

    $  systemctl list-units --type=device
    

    The type of units are:

           The following unit types are available:
    
    	1. Service units, which start and control daemons and the processes
    	   they consist of. For details see systemd.service(5).
    
    	2. Socket units, which encapsulate local IPC or network sockets in the
    	   system, useful for socket-based activation. For details about
    	   socket units see systemd.socket(5), for details on socket-based
    	   activation and other forms of activation, see daemon(7).
    
    	3. Target units are useful to group units, or provide well-known
    	   synchronization points during boot-up, see systemd.target(5).
    
    	4. Device units expose kernel devices in systemd and may be used to
    	   implement device-based activation. For details see
    	   systemd.device(5).
    
    	5. Mount units control mount points in the file system, for details
    	   see systemd.mount(5).
    
    
    	6. Automount units provide automount capabilities, for on-demand
    	   mounting of file systems as well as parallelized boot-up. See
    	   systemd.automount(5).
    
    	7. Snapshot units can be used to temporarily save the state of the set
    	   of systemd units, which later may be restored by activating the
    	   saved snapshot unit. For more information see systemd.snapshot(5).
    
    	8. Timer units are useful for triggering activation of other units
    	   based on timers. You may find details in systemd.timer(5).
    
    
    	9. Swap units are very similar to mount units and encapsulate memory
    	   swap partitions or files of the operating system. They are
    	   described in systemd.swap(5).
    
           10. Path units may be used to activate other services when file system
    	   objects change or are modified. See systemd.path(5).
    
           11. Slice units may be used to group units which manage system
    	   processes (such as service and scope units) in a hierarchical tree
    	   for resource management purposes. See systemd.slice(5).
    
           12. Scope units are similar to service units, but manage foreign
    	   processes instead of starting them as well. See systemd.scope(5).
    
           Units are named as their configuration files. Some units have special
           semantics. A detailed list is available in systemd.special(7).
