NAME         top

       systemd-delta - Find overridden configuration files

SYNOPSIS         top

       systemd-delta [OPTIONS...] [PREFIX[/SUFFIX]|SUFFIX...]

DESCRIPTION         top

       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.

OPTIONS         top

       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

           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.

       -h, --help
           Print a short help text and exit.

           Print a short version string and exit.

           Do not pipe output into a pager.

EXAMPLES         top

       To see all local configuration:


       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

EXIT STATUS         top

       On success, 0 is returned, a non-zero failure code otherwise.
