258 | See doc/README: Perl 5.8.x itself and the following modules from CPAN: | |

271 | ||
272 | =head1 DESCRIPTION | |
273 | ||
274 | This script create reports on newsgroup usage (number of postings per | |
275 | group per month) taken from result tables created by | |
276 | F<gatherstats.pl>. | |
277 | ||
278 | The time period to act on defaults to last month; you can assign | |
279 | another month via the B<-m> switch or a time period via the B<-p> | |
280 | switch; the latter takes preference. | |
281 | ||
282 | B<groupstats> will process all newsgroups by default; you can limit | |
283 | that to only some newsgroups by supplying a list of those groups via | |
284 | B<-n> (see below). You can include hierarchy levels in the output by | |
285 | adding the B<-s> switch (see below). | |
286 | ||
287 | Furthermore you can set a threshold via B<-t> so that only newsgroups | |
288 | with more postings per month will be included in the report. You can | |
289 | invert that by the B<-i> switch so only newsgroups with less than | |
290 | I<threshold> postings per month will be included. | |
291 | ||
292 | You can sort the output by number of postings per month instead of the | |
293 | default (alphabetical list of newsgroups) by using B<-q>; you can | |
294 | reverse the sorting order (from highest to lowest or in reversed | |
295 | alphabetical order) by using B<-d>. | |
296 | ||
297 | Furthermore, you can create a list of newsgroups that had consistently | |
298 | more (or less) than x postings per month during the whole report | |
299 | period by using B<-l> (together with B<i> as needed). | |
300 | ||
301 | Last but not least you can create a "best of" list of the top x | |
302 | newsgroups via B<-b> (or a "worst of" list by adding B<i>). | |
303 | ||
628a183c TH |
304 | By default, B<groupstats> will dump an alphabetical list of newsgroups, |
305 | one per line, followed by the number of postings in that group, for | |
306 | every month. You can change the output format by using B<-o> (see | |
2832c235 TH |
307 | below). Captions can be added by setting the B<-c> switch. |
308 | ||
309 | =head2 Configuration | |
310 | ||
f2ddfd8a | 311 | B<groupstats> will read its configuration from F<newsstats.conf> |
2832c235 TH |
312 | which should be present in the same directory via Config::Auto. |
313 | ||
314 | See doc/INSTALL for an overview of possible configuration options. | |
315 | ||
316 | You can override configuration options via the B<-g> switch. | |

334 | |
335 | =item B<-p> I<YYYY-MM:YYYY-MM> (period) | |

2832c235 TH |
345 | |
346 | =item B<-n> I<newsgroup(s)> (newsgroups) | |
347 | ||
348 | Limit processing to a certain set of newsgroups. I<newsgroup(s)> can | |
349 | be a single newsgroup name (de.alt.test), a newsgroup hierarchy | |
350 | (de.alt.*) or a list of either of these, separated by colons, for | |

357 | Only include newsgroups with more than I<threshold> postings per | |
358 | month. Can be inverted by the B<-i> switch so that only newsgroups | |
359 | with less than I<threshold> postings will be included. | |

361 | This setting will be ignored if B<-l> or B<-b> is set. | |
362 | ||
363 | =item B<-l> I<level> (level) | |
364 | ||
365 | Only include newsgroups with more than I<level> postings per | |
366 | month, every month during the whole reporting period. Can be inverted | |
367 | by the B<-i> switch so that only newsgroups with less than I<level> | |
368 | postings every single month will be included. Output will be ordered | |
369 | by newsgroup name, followed by month. | |
370 | ||
371 | This setting will be ignored if B<-b> is set. Overrides B<-t> and | |
78389b28 | 372 | can't be used together with B<-q>, B<-d> or B<-f>. |

377 | whole reporting period. Can be inverted by the B<-i> switch so that a | |
378 | list of the I<n> newsgroups with the least postings over the whole | |
379 | period is generated. Output will be ordered by sum of postings. | |

385 | ||
386 | Used in conjunction with B<-t>, B<-l> or B<-b> to set a lower | |
387 | threshold or level or generate a "bottom list" instead of a top list. | |
388 | ||
389 | =item B<-s> (sum per hierarchy level) | |
390 | ||
391 | Include "virtual" groups for every hierarchy level in output, for | |
392 | example: | |
393 | ||
394 | de.alt.ALL 10 | |
395 | de.alt.test 5 | |
396 | de.alt.admin 7 | |
397 | ||

399 | ||
400 | =item B<-o> I<output type> (output format) | |
401 | ||
628a183c TH |
402 | Set output format. Default is I<pretty>, which will print a header for |
403 | each new month, followed by an alphabetical list of newsgroups, each | |
404 | on a new line, followed by the number of postings in that month. | |
405 | B<groupstats> will try to align newsgroup names and posting counts. | |
406 | Usage of B<-b> will force this format; it cannot be used together with | |
407 | B<-f>. | |
408 | ||
409 | I<dump> format is used to create an easily parsable output consisting | |
410 | of an alphabetical list of newsgroups, each on a new line, followed by | |
411 | the number of postings in that month, without any alignment. This | |
412 | default format can't be used with time periods of more than one month. | |
413 | Usage of B<-f> will force this format. | |
2832c235 TH |
414 | |
415 | I<list> format is like I<dump>, but will print the month in front of | |
416 | the newsgroup name. | |
417 | ||
418 | I<dumpgroup> format can only be use with a group list (see B<-n>) of | |
419 | exactly one newsgroup and is like I<dump>, but will output months, | |
420 | followed by the number of postings. | |
421 | ||
2832c235 TH |
422 | =item B<-c> (captions) |
423 | ||
78389b28 TH |
424 | Add captions to output (reporting period, newsgroups list, threshold |
425 | and so on). | |
426 | ||
427 | This setting will be ignored if B<-f> is set. | |
2832c235 TH |
428 | |
429 | =item B<-q> (quantity of postings) | |
430 | ||
431 | Sort by number of postings instead of by newsgroup names. | |
432 | ||
433 | Cannot be used with B<-l> or B<-b>. | |
434 | ||
435 | =item B<-d> (descending) | |
436 | ||
437 | Change sort order to descending. | |
438 | ||
439 | Cannot be used with B<-l> or B<-b>. | |
440 | ||
78389b28 TH |
441 | =item B<-f> I<filename template> (output file) |
442 | ||
443 | Save output to file instead of dumping it to STDOUT. B<groupstats> | |
444 | will create one file for each month, with filenames composed by | |
445 | adding year and month to the I<filename template>, for example | |
446 | with B<-f> I<stats>: | |
447 | ||
448 | stats-2010-01 | |
449 | stats-2010-02 | |
450 | ... and so on | |
451 | ||
452 | This setting will be ignored if B<-l> or B<-b> is set. Output format | |
453 | is set to I<dump> (see above). | |
454 | ||
2832c235 TH |
455 | =item B<-g> I<table> (postings per group table) |
