242
243options :
244
245  -v | --version       Prints edpykota's version number then exits.
246  -h | --help          Prints this message then exits.
247 
248  -a | --add           Adds users and/or printers if they don't
249                       exist on the Quota Storage Server.
250                       
251  -d | --delete        Deletes users/groups from the quota storage.
252                       Printers are never deleted.
253                       
254  -c | --charge p[,j]  Sets the price per page and per job to charge
255                       for a particular printer. Job price is optional.
256                       If both are to be set, separate them with a comma.
257                       Floating point values are allowed.
258 
259  -i | --ingroups g1[,g2...]  Puts the users into each of the groups
260                              listed, separated by commas. The groups
261                              must already exist in the Quota Storage.
262 
263  -u | --users         Edit users print quotas, this is the default.
264 
265  -P | --printer p     Edit quotas on printer p only. Actually p can
266                       use wildcards characters to select only
267                       some printers. The default value is *, meaning
268                       all printers.
269                       You can specify several names or wildcards,
270                       by separating them with commas.
271 
272  -g | --groups        Edit groups print quotas instead of users.
273                         
274  -p | --prototype u|g Uses user u or group g as a prototype to set
275                       print quotas
276                       
277  -n | --noquota       Doesn't set a quota but only does accounting.
278 
279  -r | --reset         Resets the printed page counter for the user
280                       or group to zero. The life time page counter
281                       is kept unchanged.
282                       
283  -l | --limitby l     Choose if the user/group is limited in printing                     
284                       by its account balance or by its page quota.
285                       The default value is 'quota'. Allowed values
286                       are 'quota' and 'balance'.
287                       
288  -b | --balance b     Sets the user's account balance to b.                     
289                       Account balance may be increase or decreased
290                       if b is prefixed with + or -.
291                       WARNING : when decreasing account balance,
292                       the total paid so far by the user is decreased
293                       too.
294                       Groups don't have a real balance, but the
295                       sum of their users' account balance.
296                       
297  -S | --softlimit sl  Sets the quota soft limit to sl pages.                       
298 
299  -H | --hardlimit hl  Sets the quota hard limit to hl pages.
300 
301  user1 through userN and group1 through groupN can use wildcards
302  if the --add option is not set.
303 
304examples :                             
305
306  $ edpykota -p jerome john paul george ringo
307 
308  This will set print quotas for the users john, paul, george and ringo
309  to the same values than user jerome. User jerome must exist.
310 
311  $ edpykota --printer lp -S 50 -H 60 jerome
312 
313  This will set jerome's print quota on the lp printer to a soft limit
314  of 50 pages, and a hard limit of 60 pages. If either user jerome or
315  printer lp doesn't exist on the Quota Storage Server then nothing is done.
316
317  $ edpykota --add --printer lp --ingroups coders,it -S 50 -H 60 jerome
318 
319  Same as above, but if either user jerome or printer lp doesn't exist
320  on the Quota Storage Server they are automatically added. Also
321  user jerome is put into the groups "coders" and "it" which must
322  already exist in the Quota Storage.
323  WARNING : the CUPS PPD file for this printer or the /etc/printcap
324            file (depending on your printing backend)  must still be
325            modified manually, as well as pykota's configuration file
326            for a new printer to be managed successfully.
327           
328  $ edpykota -g -S 500 -H 550 financial support           
329 
330  This will set print quota soft limit to 500 pages and hard limit
331  to 550 pages for groups financial and support on all printers.
332 
333  $ edpykota --reset jerome "jo*"
334 
335  This will reset jerome's page counter to zero on all printers, as
336  well as every user whose name begins with 'jo'.
337  Their life time page counter on each printer will be kept unchanged.
338 
339  $ edpykota --printer hpcolor --noquota jerome
340 
341  This will tell PyKota to not limit jerome when printing on the
342  hpcolor printer. All his jobs will be allowed on this printer, but
343  accounting of the pages he prints will still be kept.
344  Print Quotas for jerome on other printers are unchanged.
345 
346  $ edpykota --limitby balance jerome
347 
348  This will tell PyKota to limit jerome by his account's balance
349  when printing.
350 
351  $ edpykota --balance +10.0 jerome
352 
353  This will increase jerome's account balance by 10.0 (in your
354  own currency). You can decrease the account balance with a
355  dash prefix, and set it to a fixed amount with no prefix.
356 
357  $ edpykota --delete jerome rachel
358 
359  This will completely delete jerome and rachel from the Quota Storage
360  database. All their quotas and jobs will be deleted too.
361 
362  $ edpykota --printer lp --charge 0.1
363 
364  This will set the page price for printer lp to 0.1. Job price
365  will not be changed.
