systemd-delta(1)

NAME

   systemd-delta - Find overridden configuration files

SYNOPSIS

   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 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.

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
           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.

       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.

EXAMPLES

   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

EXIT STATUS

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