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
       commandline argument is not given at all, all configuration files will be analyzed. See
       below for some examples.

OPTIONS
       The following options are understood:

       -h, --help
	   Prints a short help text and exits.

       --version
	   Prints a short version string and exits.

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

       -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.

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.
