| 109 | |
| 110 | compress-files - Gzip files not modified over a given period of time |
| 111 | |
| 112 | =head1 SYNOPSIS |
| 113 | |
| 114 | compress-files [options] <directory> [<directory> ...] |
| 115 | |
| 116 | =head1 DESCRIPTION |
| 117 | |
| 118 | This program is part of mharc. This program is used to compress |
| 119 | files that have not been modified over a given period of time. |
| 120 | |
| 121 | =head1 OPTIONS |
| 122 | |
| 123 | =over |
| 124 | |
| 125 | =item C<-debug> |
| 126 | |
| 127 | Print out alot of status information. |
| 128 | |
| 129 | =item C<-help> |
| 130 | |
| 131 | Print out usage information. |
| 132 | |
| 133 | =item C<-n> |
| 134 | |
| 135 | Print the commands that would be executed, but do not execute them. |
| 136 | |
| 137 | =item C<-mbox-mode> |
| 138 | |
| 139 | A hack for compress mailbox files. When this option is specified, |
| 140 | the default C<-pattern> is C<^\d+(?:-\d+)?$>. This pattern basically |
| 141 | searches for files with names in YYYY and YYYY-MM format. Files with |
| 142 | names in YYYY format are handled slightly different. When checking |
| 143 | if the file can be compressed, a year is added to C<-mtime>. |
| 144 | |
| 145 | =item C<-man> |
| 146 | |
| 147 | Print out manpage. |
| 148 | |
| 149 | =item C<-mtime> I<days> |
| 150 | |
| 151 | Modification time in days a file has to be older than to get compressed. |
| 152 | If this option is not specified, 31 days is used. |
| 153 | |
| 154 | =item C<-pattern> I<regex> |
| 155 | |
| 156 | Perl regular expression that represents files that should be |
| 157 | checked. If not specifed, the following regex is used: |
| 158 | C<^[^.]>. |
