43 | command line usage : |
---|
44 | |
---|
45 | pykotme [options] [files] |
---|
46 | |
---|
47 | options : |
---|
48 | |
---|
49 | -v | --version Prints pykotme's version number then exits. |
---|
50 | -h | --help Prints this message then exits. |
---|
51 | |
---|
52 | -P | --printer p Gives a quote for this printer only. Actually p can |
---|
53 | use wildcards characters to select only |
---|
54 | some printers. The default value is *, meaning |
---|
55 | all printers. |
---|
56 | You can specify several names or wildcards, |
---|
57 | by separating them with commas. |
---|
58 | |
---|
59 | examples : |
---|
60 | |
---|
61 | $ pykotme --printer apple file1.ps file2.ps |
---|
62 | |
---|
63 | This will give a print quote to the current user. The quote will show |
---|
64 | the price and size of a job consisting in file1.ps and file2.ps |
---|
65 | which would be sent to the apple printer. |
---|
66 | |
---|
67 | $ pykotme --printer apple,hplaser <file1.ps |
---|
68 | |
---|
69 | This will give a print quote to the current user. The quote will show |
---|
70 | the price and size of a job consisting in file1.ps as read from |
---|
71 | standard input, which would be sent to the apple or hplaser |
---|
72 | printer. |
---|
73 | |
---|
74 | $ pykotme |
---|
75 | |
---|
76 | This will give a quote for a job consisting of what is on standard |
---|
77 | input. The quote will list the job size, and the price the job |
---|
78 | would cost on each printer. |
