---|
| 59 | |
---|
| 60 | options : |
---|
| 61 | |
---|
| 62 | -v | --version Prints pkrefund's version number then exits. |
---|
| 63 | -h | --help Prints this message then exits. |
---|
| 64 | |
---|
| 65 | -f | --force Doesn't ask for confirmation before refunding jobs. |
---|
| 66 | -r | --reason txt Sets textual information to explain the refunding. |
---|
| 67 | |
---|
[3084] | 68 | -l | --logo img Use the image as the receipt's logo. The logo will |
---|
| 69 | be drawn at the center top of the page. The default |
---|
| 70 | logo is /usr/share/pykota/logos/pykota.jpeg |
---|
| 71 | |
---|
| 72 | -p | --pagesize sz Sets sz as the page size. Most well known |
---|
| 73 | page sizes are recognized, like 'A4' or 'Letter' |
---|
| 74 | to name a few. The default size is A4. |
---|
| 75 | |
---|
| 76 | -n | --number N Sets the number of the first receipt. This number |
---|
| 77 | will automatically be incremented for each receipt. |
---|
| 78 | |
---|
| 79 | -o | --output f.pdf Defines the name of the PDF file which will contain |
---|
| 80 | the receipts. If not set, then no PDF file will |
---|
| 81 | be created. If set to '-', then --force is assumed, |
---|
| 82 | and the PDF document is sent to standard output. |
---|
| 83 | |
---|
| 84 | -u | --unit u Defines the name of the unit to use on the receipts. |
---|
| 85 | The default unit is 'Credits', optionally translated |
---|
| 86 | to your native language if it is supported by PyKota. |
---|
| 87 | |
---|

---|
[3063] | 89 | Use the filter expressions to extract only parts of the |
---|
| 90 | datas. Allowed filters are of the form : |
---|
| 91 | |
---|
| 92 | key=value |
---|
| 93 | |
---|
| 94 | Allowed keys for now are : |
---|
| 95 | |
---|
| 96 | username User's name |
---|
| 97 | printername Printer's name |
---|
| 98 | hostname Client's hostname |
---|
| 99 | jobid Job's Id |
---|
| 100 | billingcode Job's billing code |
---|
| 101 | start Job's date of printing |
---|
| 102 | end Job's date of printing |
---|
| 103 | |
---|
[3068] | 104 | Dates formatting with 'start' and 'end' filter keys : |
---|
| 105 | |
---|
| 106 | YYYY : year boundaries |
---|
| 107 | YYYYMM : month boundaries |
---|
| 108 | YYYYMMDD : day boundaries |
---|
| 109 | YYYYMMDDhh : hour boundaries |
---|
| 110 | YYYYMMDDhhmm : minute boundaries |
---|
| 111 | YYYYMMDDhhmmss : second boundaries |
---|
| 112 | yesterday[+-NbDays] : yesterday more or less N days (e.g. : yesterday-15) |
---|
| 113 | today[+-NbDays] : today more or less N days (e.g. : today-15) |
---|
| 114 | tomorrow[+-NbDays] : tomorrow more or less N days (e.g. : tomorrow-15) |
---|
| 115 | now[+-NbDays] : now more or less N days (e.g. now-15) |
---|
| 116 | |
---|
| 117 | 'now' and 'today' are not exactly the same since today represents the first |
---|
| 118 | or last second of the day depending on if it's used in a start= or end= |
---|
| 119 | date expression. The utility to be able to specify dates in the future is |
---|
| 120 | a question which remains to be answered :-) |
---|
| 121 | |
---|
[3063] | 122 | Contrary to other PyKota management tools, wildcard characters are not |
---|
| 123 | expanded, so you can't use them. |
---|
| 124 | |
---|
| 125 | Examples : |
---|
| 126 | |
---|
[3084] | 127 | $ pkrefund --output /tmp/receipts.pdf jobid=503 |
---|
[3063] | 128 | |
---|
| 129 | This will refund all jobs which Id is 503. BEWARE : installing CUPS |
---|
[3084] | 130 | afresh will reset the first job id at 1, so you probably want to use |
---|
| 131 | a more precise filter as explained below. A confirmation will |
---|
| 132 | be asked for each job to refund, and a PDF file named /tmp/receipts.pdf |
---|
| 133 | will be created which will contain printable receipts. |
---|
[3063] | 134 | |
---|
| 135 | $ pkrefund --reason "Hardware problem" jobid=503 start=today-7 |
---|
| 136 | |
---|
| 137 | Refunds all jobs which id is 503 but which were printed during the |
---|
| 138 | past week. The reason will be marked as being an hardware problem. |
---|
| 139 | |
---|
| 140 | $ pkrefund --force username=jerome printername=HP2100 |
---|
| 141 | |
---|
| 142 | Refunds all jobs printed by user jerome on printer HP2100. No |
---|
| 143 | confirmation will be asked. |
---|
| 144 | |
---|
| 145 | $ pkrefund --force printername=HP2100 start=200602 end=yesterday |
---|
| 146 | |
---|
| 147 | Refunds all jobs printed on printer HP2100 between February 1st 2006 |
---|
| 148 | and yesterday. No confirmation will be asked. |
