[_RUN-PARTS_(8)](https://www.chedong.com/phpMan.php/man/RUN-PARTS/8/markdown)                           System Manager's Manual                          [_RUN-PARTS_(8)](https://www.chedong.com/phpMan.php/man/RUN-PARTS/8/markdown)

## NAME
       run-parts - run scripts or programs in a directory

## SYNOPSIS
       **run-parts    **[--test]    [--verbose]   [--debug]   [--report]   [--lsbsysinit]   [--regex=RE]
       [--umask=umask] [--arg=argument] [--exit-on-error] [--help] [--version] [--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 directories are silently ignored.

       If neither the --lsbsysinit option nor the --regex option is given then the names  must  con‐
       sist  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 (^[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 sequentially in the lexical sort order (according to the C/POSIX locale charac‐
       ter 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 ac‐
              tually 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.

### -d, --debug
              print to stderr which scripts get selected for running and which don't.

### --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=_
              sets the umask to _umask_ before running the scripts.  _umask_ should be specified in  oc‐
              tal.  By default the umask is set to 022.

### -a, --arg=_
              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
