run-parts - run scripts or programs in a directory


   run-parts  [--test]  [--verbose] [--report] [--lsbsysinit] [--regex=RE]
   [--umask=umask] [--arg=argument] [--exit-on-error] [--help] [--version]
   [--list] [--reverse] [--] DIRECTORY

   run-parts -V


   run-parts  runs  all  the  executable  files  named  within constraints
   described  below,  found  in  directory  directory.   Other  files  and
   directories are silently ignored.

   If neither the --lsbsysinit option nor the --regex option is given then
   the names must consist entirely of ASCII upper- and lower-case letters,
   ASCII digits, ASCII underscores, and ASCII minus-hyphens.

   If  the  --lsbsysinit  option  is given, then the names must not end in
   .dpkg-old  or .dpkg-dist or .dpkg-new or .dpkg-tmp, and must belong  to
   one  or more of the following namespaces: the LANANA-assigned namespace
   (^[a-z0-9]+$);   the   LSB   hierarchical   and   reserved   namespaces
   (^_?([a-z0-9_.]+-)+[a-z0-9]+$);  and  the  Debian cron script namespace

   If the --regex option  is  given,  the  names  must  match  the  custom
   extended regular expression specified as that option's argument.

   Files  are  run  in  the  lexical  sort order (according to the C/POSIX
   locale character collation rules) of their names unless  the  --reverse
   option is given, in which case they are run in the opposite order.


   --test print  the  names  of  the scripts which would be run, but don't
          actually run them.

   --list print the names of  the  all  matching  files  (not  limited  to
          executables), but don't actually run them. This option cannot be
          used with --test.

   -v, --verbose
          print the name of each script to stderr before running.

          similar to --verbose, but only prints the name of scripts  which
          produce  output.   The  script's name is printed to whichever of
          stdout or stderr the script first produces output on.

          reverse the scripts' execution order.

          exit as soon as a script returns with a non-zero exit code.

          use LSB namespaces instead of classical behavior.

          run each script in a separate process session.  If you use  this
          option,  killing  run-parts  will not kill the currently running
          script, it will run until completion.

          validate filenames against custom  extended  regular  expression
          RE.  See the EXAMPLES section for an example.

   -u, --umask=umask
          sets  the  umask  to  umask  before  running the scripts.  umask
          should be specified in octal.  By default the umask  is  set  to

   -a, --arg=argument
          pass  argument to the scripts.  Use --arg once for each argument
          you want passed.

   --     specifies that this is the end of  the  options.   Any  filename
          after  --  will  be  not  be interpreted as an option even if it
          starts with a hyphen.

   -h, --help
          display usage information and exit.

   -V, --version
          display version and copyright and exit.


   Print the names of all files in /etc that start with `p' and  end  with

   run-parts --list --regex '^p.*d$' /etc
