systemd-delta - Find overridden configuration files
systemd-delta [OPTIONS...] [PREFIX | 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.
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.
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.
