systemd-delta - Find overridden configuration files
systemd-delta [OPTIONS...] [PREFIX[/SUFFIX]|SUFFIX...]
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.
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.
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
On success, 0 is returned, a non-zero failure code otherwise.
