Config::Model::Systemd(3) Editor and validator for systemd configuration files


version 0.007


command line

Requires App::Cme:

 $ cme edit systemd-user
 $ cme check systemd-user
 # cme edit systemd
 # cme check systemd

Perl program

 use Config::Model qw/cme/;
 cme('systemd-user')->modify('socket:free-imap-tunnel Socket Accept=yes') ;


This module provides a configuration editor for the configuration file of systemd, i.e. all files in "~/.config/systemd/user/" or all files in "/etc/systemd/system/"

Ok. I simplified. Actually, this module provides the configuration models of Systemd configuration file that cme, Config::Model and Config::Model::TkUI use to provide a configuration editor and checker.

invoke editor

The following command loads user systemd files (from "~/.config/systemd/user/" and launch a graphical editor:

 cme edit systemd-user

Likewise, the following command loads system systemd configuration files and launch a graphical editor:

 sudo cme edit systemd

Just check systemd configuration

You can also use cme to run sanity checks on the configuration file:

 cme check systemd-user
 cme check systemd

Use in Perl program

As of Config::Model 2.086, a ``cme(...)'' in cme function is exported to modify configuration in a Perl program. For instance:

 use Config::Model qw/cme/; # also import cme function
 # call cme for systemd-user, modify ans save my-imap-tunnel.socket file.
 cme('systemd-user')->modify('socket:my-imap-tunnel Socket Accept=yes') ;

Similarly, system Systemd files can be modified using "systemd" application:

 use Config::Model qw/cme/;
 cme('systemd')->modify(...) ;

For more details and parameters, please see cme, modify, load and save documentation.


The list of supported parameters is extracted from the xml documentation provided by systemd project. This list is expected to be rather complete.

The properties of these parameters are inferred from the description of the parameters and are probably less accurate. In case of errors, please log a bug.


For now, only "unit", "socket" and "service" files are supported. Please log a wishlist bug if you need other unit types to be supported.


In case of issue, please log a bug on <>.
