NAME¶systemd-delta - Find overridden configuration files
systemd-delta [OPTIONS...] [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 /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.
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--diff=
Show masked filesequivalent
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.
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 --type=extended /run/systemd/system
EXIT STATUS¶On success, 0 is returned, a non-zero failure code otherwise.
