41 | Generates print quota reports. |
---|
42 | |
---|
43 | command line usage : |
---|
44 | |
---|
45 | repykota [options] |
---|
46 | |
---|
47 | options : |
---|
48 | |
---|
49 | -v | --version Prints repykota's version number then exits. |
---|
50 | -h | --help Prints this message then exits. |
---|
51 | |
---|
52 | -u | --users Generates a report on users quota, this is |
---|
53 | the default. |
---|
54 | |
---|
55 | -g | --groups Generates a report on group quota instead of users. |
---|
56 | |
---|
57 | -P | --printer p Report quotas on this printer only. Actually p can |
---|
58 | use wildcards characters to select only |
---|
59 | some printers. The default value is *, meaning |
---|
60 | all printers. |
---|
61 | You can specify several names or wildcards, |
---|
62 | by separating them with commas. |
---|
63 | |
---|
64 | examples : |
---|
65 | |
---|
66 | $ repykota --printer lp |
---|
67 | |
---|
68 | This will print the quota status for all users who use the lp printer. |
---|
69 | |
---|
70 | $ repykota |
---|
71 | |
---|
72 | This will print the quota status for all users on all printers. |
---|
73 | |
---|
74 | $ repykota --printer "laser*,*pson" jerome "jo*" |
---|
75 | |
---|
76 | This will print the quota status for user jerome and all users |
---|
77 | whose name begins with "jo" on all printers which name begins |
---|
78 | with "laser" or ends with "pson". |
---|
79 | |
---|
80 | If launched by an user who is not a PyKota administrator, additionnal |
---|
81 | arguments representing users or groups names are ignored, and only the |

82 | current user/group is reported. |
