.SH DESCRIPTION
.PP
.B run\-parts
runs all the executable files named within constraints described below, found
in directory
.IR 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 rpm backups (.rpmsave, .rpmnew, .rpmorig), 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.

.SH OPTIONS
.TP
.B \-\-test
print the names of the scripts which would be run, but don't actually run
them.
.TP
.B \-\-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.
.TP
.B \-v, \-\-verbose
print the name of each script to stderr before running.
.TP
.B \-\-report
similar to
.BR \-\-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.
.TP
.B \-\-reverse
reverse the scripts' execution order.
.TP
.B \-\-exit\-on\-error
exit as soon as a script returns with a non-zero exit code.
.TP
.B \-\-lsbsysinit
use LSB namespaces instead of classical behavior.
.TP
.B \-\-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.
.TP
.BI \-\-regex= RE
validate filenames against custom extended regular expression
.IR RE .
See the EXAMPLES section for an example.
.TP
.BI "\-u, \-\-umask=" umask
sets the umask to
.I umask
before running the scripts.
.I umask
should be specified in octal.  By default the umask is set to 022.
.TP
.BI "\-a, \-\-arg=" argument
pass
.I argument
to the scripts.  Use
.B --arg
once for each argument you want passed.
.TP
.B "\-\-"
specifies that this is the end of the options.  Any filename after
.B "\-\-"
will be not be interpreted as an option even if it starts with a
hyphen.
.TP
.B \-h, \-\-help
display usage information and exit.
.TP
.B \-V, \-\-version
display version and copyright and exit.

.SH EXAMPLES
.P
