.SH "NAME"
systemd.scope \- Scope unit configuration
.SH "SYNOPSIS"
.PP
\fIscope\fR\&.scope
.SH "DESCRIPTION"
.PP
Scope units are not configured via unit configuration files, but are only created programmatically using the bus interfaces of systemd\&. They are named similar to filenames\&. A unit whose name ends in
"\&.scope"
refers to a scope unit\&. Scopes units manage a set of system processes\&. Unlike service units, scope units manage externally created processes, and do not fork off processes on its own\&.
.PP
The main purpose of scope units is grouping worker processes of a system service for organization and for managing resources\&.
.PP
\fBsystemd\-run \fR\fB\fB\-\-scope\fR\fR
may be used to easily launch a command in a new scope unit from the command line\&.
.PP
See the
\m[blue]\fBNew Control Group Interfaces\fR\m[]\&\s-2\u[1]\d\s+2
for an introduction on how to make use of scope units from programs\&.
.PP
Unless
\fIDefaultDependencies=false\fR
is used, scope units will implicitly have dependencies of type
\fIConflicts=\fR
and
\fIBefore=\fR
on
shutdown\&.target\&. These ensure that scope units are removed prior to system shutdown\&. Only scope units involved with early boot or late system shutdown should disable this option\&.
