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 /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.
The following options are understood:
Prints a short help text and exits.
Prints a short version string and exits.
Do not pipe output into a pager.
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:
Show masked files
Show overridden files that while overridden, do not differ in content.
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.
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.
