326A Print Quota editor for PyKota.

330  edpykota [options] user1 user2 ... userN
331 
332  edpykota [options] group1 group2 ... groupN
333
334options :
335
336  -v | --version       Prints edpykota's version number then exits.
337  -h | --help          Prints this message then exits.
338 
339  -a | --add           Adds users and/or printers if they don't
340                       exist on the Quota Storage Server.
341                       
342  -d | --delete        Deletes users/groups from the quota storage.
343                       Printers are never deleted.
344                       
345  -c | --charge p[,j]  Sets the price per page and per job to charge
346                       for a particular printer. Job price is optional.
347                       If both are to be set, separate them with a comma.
348                       Floating point values are allowed.
349                       
350  -o | --overcharge f  Sets the overcharging factor applied to the user
351                       when computing the cost of a print job. Positive or
352                       negative floating point values are allowed,
353                       this allows you to do some really creative
354                       things like giving money to an user whenever
355                       he prints. The number of pages in a print job
356                       is not modified by this coefficient, only the
357                       cost of the job for a particular user.
358                       Only users have a coefficient.
359 
360  -i | --ingroups g1[,g2...]  Puts the users into each of the groups
361                              listed, separated by commas. The groups
362                              must already exist in the Quota Storage.
363 
364  -u | --users         Edit users print quotas, this is the default.
365 
366  -P | --printer p     Edit quotas on printer p only. Actually p can
367                       use wildcards characters to select only
368                       some printers. The default value is *, meaning
369                       all printers.
370                       You can specify several names or wildcards,
371                       by separating them with commas.
372 
373  -G | --pgroups pg1[,pg2...] Adds the printer(s) to the printer groups
374                       pg1, pg2, etc... which must already exist.
375                       A printer group is just like a normal printer,
376                       only that it is usually unknown from the printing
377                       system. Create printer groups exactly the same
378                       way that you create printers, then add other
379                       printers to them with this option.
380                       Accounting is done on a printer and on all
381                       the printer groups it belongs to, quota checking
382                       is done on a printer and on all the printer groups
383                       it belongs to.
384 
385  -g | --groups        Edit users groups print quotas instead of users.
386                         
387  -p | --prototype u|g Uses user u or group g as a prototype to set
388                       print quotas
389                       
390  -n | --noquota       Doesn't set a quota but only does accounting.
391 
392  -r | --reset         Resets the actual page counter for the user
393                       or group to zero on the specified printers.
394                       The life time page counter is kept unchanged.
395                       
396  -R | --hardreset     Resets the actual and life time page counters
397                       for the user or group to zero on the specified
398                       printers. This is a shortcut for '--used 0'.
399                       
400  -l | --limitby l     Choose if the user/group is limited in printing                     
401                       by its account balance or by its page quota.
402                       The default value is 'quota'. Allowed values
403                       are 'quota' 'balance' 'quota-then-balance' and
404                       'balance-then-quota'.
405                       WARNING : quota-then-balance and balance-then-quota
406                       are not yet implemented.
407                       
408  -b | --balance b     Sets the user's account balance to b.                     
409                       Account balance may be increase or decreased
410                       if b is prefixed with + or -.
411                       WARNING : when decreasing account balance,
412                       the total paid so far by the user is decreased
413                       too.
414                       Groups don't have a real balance, but the
415                       sum of their users' account balance.
416                       
417  -S | --softlimit sl  Sets the quota soft limit to sl pages.                       
418 
419  -H | --hardlimit hl  Sets the quota hard limit to hl pages.
420
421  -U | --used usage    Sets the pagecounters for the user to usage pages;
422                       useful for migrating users from a different system
423                       where they have already used some pages. Actual
424                       and Life Time page counters may be increased or decreased
425                       if usage is prefixed with + or -.
426                       WARNING : BOTH page counters are modified in all cases,
427                       so be careful.
428                       NB : if 'usage' equals '0', then the action taken is
429                       the same as if --hardreset was used.
430
431  user1 through userN and group1 through groupN can use wildcards
432  if the --add option is not set.
433 
434examples :                             
435
436  $ edpykota --add -p jerome john paul george ringo/ringo@example.com
437 
438  This will add users john, paul, george and ringo to the quota
439  database, and set their print quotas to the same values than user
440  jerome. User jerome must already exist.
441  User ringo's email address will also be set to 'ringo@example.com'
442 
443  $ edpykota --printer lp -S 50 -H 60 jerome
444 
445  This will set jerome's print quota on the lp printer to a soft limit
446  of 50 pages, and a hard limit of 60 pages. If either user jerome or
447  printer lp doesn't exist on the Quota Storage Server then nothing is done.
448
449  $ edpykota --add --printer lp --ingroups coders,it -S 50 -H 60 jerome
450 
451  Same as above, but if either user jerome or printer lp doesn't exist
452  on the Quota Storage Server they are automatically added. Also
453  user jerome is put into the groups "coders" and "it" which must
454  already exist in the Quota Storage.
455           
456  $ edpykota -g -S 500 -H 550 financial support           
457 
458  This will set print quota soft limit to 500 pages and hard limit
459  to 550 pages for groups financial and support on all printers.
460 
461  $ edpykota --reset jerome "jo*"
462 
463  This will reset jerome's page counter to zero on all printers, as
464  well as every user whose name begins with 'jo'.
465  Their life time page counter on each printer will be kept unchanged.
466  You can also reset the life time page counters by using the
467  --hardreset | -R command line option.
468 
469  $ edpykota --printer hpcolor --noquota jerome
470 
471  This will tell PyKota to not limit jerome when printing on the
472  hpcolor printer. All his jobs will be allowed on this printer, but
473  accounting of the pages he prints will still be kept.
474  Print Quotas for jerome on other printers are unchanged.
475 
476  $ edpykota --limitby balance jerome
477 
478  This will tell PyKota to limit jerome by his account's balance
479  when printing.
480 
481  $ edpykota --balance +10.0 jerome
482 
483  This will increase jerome's account balance by 10.0 (in your
484  own currency). You can decrease the account balance with a
485  dash prefix, and set it to a fixed amount with no prefix.
486 
487  $ edpykota --delete jerome rachel
488 
489  This will completely delete jerome and rachel from the Quota Storage
490  database. All their quotas and jobs will be deleted too.
491 
492  $ edpykota --printer lp --charge 0.1
493 
494  This will set the page price for printer lp to 0.1. Job price
495  will not be changed.
496 
497  $ edpykota --printer hplj1,hplj2 --pgroups Laser,HP
498 
499  This will put printers hplj1 and hplj2 in printers groups Laser and HP.
500  When printing either on hplj1 or hplj2, print quota will also be
501  checked and accounted for on virtual printers Laser and HP.
502 
503  $ edpykota --overcharge 2.5 poorstudent
504 
505  This will overcharge the poorstudent user by a factor of 2.5.
506 
507  $ edpykota --overcharge -1 jerome
508 
509  User jerome will actually earn money whenever he prints.
510 
511  $ edpykota --overcharge 0 boss
512 
513  User boss can print at will, it won't cost him anything because the
514  cost of each print job will be multiplied by zero before charging
515  his account.
