NAME
       systemd-delta - Find overridden configuration files

SYNOPSIS
       systemd-delta [OPTIONS...] [PREFIX[/SUFFIX]|SUFFIX...]

DESCRIPTION
       systemd-delta may be used to identify and compare configuration files
       that override other configuration files. Files in /etc have highest
       priority, files in /run have the second highest priority, ..., files in
       /lib have lowest priority. Files in a directory with higher priority
       override files with the same name in directories of lower priority. In
       addition, certain configuration files can have ".d" directories which
       contain "drop-in" files with configuration snippets which augment the
       main configuration file. "Drop-in" files can be overriden in the same
       way by placing files with the same name in a directory of higher
       priority (except that in case of "drop-in" files, both the "drop-in"
       file name and the name of the containing directory, which corresponds
       to the name of the main configuration file, must match). For a fuller
       explanation, see systemd.unit(5).

       The command line argument will be split into a prefix and a suffix.
       Either is optional. The prefix must be one of the directories
       containing configuration files (/etc, /run, /usr/lib, ...). If it is
       given, only overriding files contained in this directory will be shown.
       Otherwise, all overriding files will be shown. The suffix must be a
       name of a subdirectory containing configuration files like tmpfiles.d,
       sysctl.d or systemd/system. If it is given, only configuration files in
       this subdirectory (across all configuration paths) will be analyzed.
       Otherwise, all configuration files will be analyzed. If the command
       line argument is not given at all, all configuration files will be
       analyzed. See below for some examples.

OPTIONS
       The following options are understood:

       -t, --type=
	   When listing the differences, only list those that are asked for.
	   The list itself is a comma-separated list of desired difference
	   types.

	   Recognized types are:

	   masked
	       Show masked files

	   equivalent
	       Show overridden files that while overridden, do not differ in
	       content.

	   redirected
	       Show files that are redirected to another.

	   overridden
	       Show overridden, and changed files.

	   extended
	       Show *.conf files in drop-in directories for units.

	   unchanged
	       Show unmodified files too.


       --diff=
	   When showing modified files, when a file is overridden show a diff
	   as well. This option takes a boolean argument. If omitted, it
	   defaults to true.

       -h, --help
	   Print a short help text and exit.

       --version
	   Print a short version string and exit.

       --no-pager
	   Do not pipe output into a pager.

EXAMPLES
       To see all local configuration:

	   systemd-delta

       To see all runtime configuration:

	   systemd-delta /run

       To see all system unit configuration changes:

	   systemd-delta systemd/system

       To see all runtime "drop-in" changes for system units:

	   systemd-delta --type=extended /run/systemd/system

EXIT STATUS
       On success, 0 is returned, a non-zero failure code otherwise.
