=head1 SYNOPSIS |
95
|
|
|
|
|
|
|
|
96
|
|
|
|
|
|
|
Run::Parts offers functionality of Debian's L<run-parts(8)> tool in |
97
|
|
|
|
|
|
|
Perl. |
98
|
|
|
|
|
|
|
|
99
|
|
|
|
|
|
|
run-parts runs all the executable files named within constraints |
100
|
|
|
|
|
|
|
described in L<run-parts(8)> and L<Run::Parts::Perl>, found |
101
|
|
|
|
|
|
|
in the given directory. Other files and directories are silently |
102
|
|
|
|
|
|
|
ignored. |
103
|
|
|
|
|
|
|
|
104
|
|
|
|
|
|
|
Additionally it can just print the names of the all matching files |
105
|
|
|
|
|
|
|
(not limited to executables, but ignores blacklisted files like |
106
|
|
|
|
|
|
|
e.g. backup files), but don't actually run them. |
107
|
|
|
|
|
|
|
|
108
|
|
|
|
|
|
|
This is useful when functionality or configuration is split over |
109
|
|
|
|
|
|
|
multiple files in one directory. A typical convention is that the |
110
|
|
|
|
|
|
|
directory name ends in ".d". Common examples for such split |
111
|
|
|
|
|
|
|
configuration directories: |
112
|
|
|
|
|
|
|
|
113
|
|
|
|
|
|
|
/etc/cron.d/ |
114
|
|
|
|
|
|
|
/etc/apt/apt.conf.d/ |
115
|
|
|
|
|
|
|
/etc/apt/sources.list.d/, |
116
|
|
|
|
|
|
|
/etc/aptitude-robot/pkglist.d/ |
117
|
|
|
|
|
|
|
/etc/logrotate.d/ |

=head1 BACKENDS |
147
|
|
|
|
|
|
|
|
148
|
|
|
|
|
|
|
L<Run::Parts> contains two backend implementations. |
149
|
|
|
|
|
|
|
L<Run::Parts::Debian> actually uses /bin/run-parts and |
150
|
|
|
|
|
|
|
L<Run::Parts::Perl> is a pure Perl implementation of a basic set of |
151
|
|
|
|
|
|
|
L<run-parts(8)>' functionality. |
152
|
|
|
|
|
|
|
|
153
|
|
|
|
|
|
|
L<Run::Parts::Debian> may or may not work with RedHat's simplified |
154
|
|
|
|
|
|
|
shell-script based reimplementation of Debian's L<run-parts(8)>. |
155
|
|
|
|
|
|
|
|
156
|
|
|
|
|
|
|
By default L<Run::Parts> uses L<Run::Parts::Debian> if /bin/run-parts |
157
|
|
|
|
|
|
|
exists, L<Run::Parts::Perl> otherwise. But you can also choose any of |
158
|
|
|
|
|
|
|
the backends explicitly. |
