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, /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:
When listing the differences, only list those that are asked for.
The list itself is a comma-separated list of desired difference
Recognized types are:
Show masked files
Show overridden files that while overridden, do not differ in
Show files that are redirected to another.
Show overridden, and changed files.
Show *.conf files in drop-in directories for units.
Show unmodified files too.
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.
Print a short help text and exit.
Print a short version string and exit.
Do not pipe output into a pager.
To see all local configuration:
To see all runtime configuration:
To see all system unit configuration changes:
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.
