NAME
       systemd-delta - Find overridden configuration files

SYNOPSIS

       systemd-delta [OPTIONS...] [PREFIX | 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 /usr/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 overridden 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.

	       Added in version 205.

	   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.
