run-parts

RUN-PARTS(8)						      System Manager's Manual						      RUN-PARTS(8)

NAME

       run-parts - run scripts or programs in a directory

SYNOPSIS

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

       run-parts -V

DESCRIPTION

       run-parts runs all the executable files named within constraints described below, found in directory directory.	Other files  and  directo-
       ries 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 let-
       ters, 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 (^[a-zA-Z0-9_-]+$).

       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.

OPTIONS

       --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.

       --report
	      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
	      reverse the scripts' execution order.

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

       --lsbsysinit
	      use LSB namespaces instead of classical behavior.

       --new-session
	      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.

       --regex=RE
	      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 022.

       -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.

EXAMPLES

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

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