96 | command line usage : |

97 | |
---|
98 | pykotme [options] [files] |
---|
99 | |
---|
100 | options : |
---|
101 | |
---|
102 | -v | --version Prints pykotme's version number then exits. |
---|
103 | -h | --help Prints this message then exits. |
---|
104 | |
---|
105 | -P | --printer p Gives a quote for this printer only. Actually p can |
---|
106 | use wildcards characters to select only |
---|
107 | some printers. The default value is *, meaning |
---|
108 | all printers. |
---|
109 | You can specify several names or wildcards, |
---|
110 | by separating them with commas. |
---|
111 | |
---|
112 | examples : |
---|
113 | |
---|
114 | $ pykotme --printer apple file1.ps file2.ps |
---|
115 | |
---|
116 | This will give a print quote to the current user. The quote will show |
---|
117 | the price and size of a job consisting in file1.ps and file2.ps |
---|
118 | which would be sent to the apple printer. |
---|
119 | |
---|
120 | $ pykotme --printer apple,hplaser <file1.ps |
---|
121 | |
---|
122 | This will give a print quote to the current user. The quote will show |
---|
123 | the price and size of a job consisting in file1.ps as read from |
---|
124 | standard input, which would be sent to the apple or hplaser |
---|
125 | printer. |
---|
126 | |
---|
127 | $ pykotme |
---|
128 | |
---|
129 | This will give a quote for a job consisting of what is on standard |
---|
130 | input. The quote will list the job size, and the price the job |
---|
131 | would cost on each printer. |
