33 | |
---|
34 | A Print Quota editor for PyKota. |
---|
35 | |
---|
36 | command line usage : |
---|
37 | |
---|
38 | edpykota [options] user1 user2 ... userN |
---|
39 | |
---|
40 | edpykota [options] group1 group2 ... groupN |
---|
41 | |
---|
42 | options : |
---|
43 | |
---|
44 | -v | --version Prints edpykota's version number then exits. |
---|
45 | -h | --help Prints this message then exits. |
---|
46 | |
---|
47 | -a | --add Adds users or groups print quota entries if |
---|
48 | they don't exist in database. |
---|
49 | |
---|
50 | -d | --delete Deletes users or groups print quota entries. |
---|
51 | Users or groups are never deleted, you have |
---|
52 | to use the pkusers command to delete them. |
---|
53 | The history will be purge from all matching |
---|
54 | jobs, unless -g | --groups is used. |
---|
55 | |
---|
56 | -P | --printer p Edit quotas on printer p only. Actually p can |
---|
57 | use wildcards characters to select only |
---|
58 | some printers. The default value is *, meaning |
---|
59 | all printers. |
---|
60 | You can specify several names or wildcards, |
---|
61 | by separating them with commas. |
---|
62 | |
---|
63 | -g | --groups Edit groups print quota entries instead of |
---|
64 | users print quota entries. |
---|
65 | |
---|
66 | -L | --list Lists users or groups print quota entries. |
---|
67 | |
---|
68 | -n | --noquota Sets both soft and hard limits to None for users |
---|
69 | or groups print quota entries. |
---|
70 | |
---|
71 | -r | --reset Resets the actual page counter for the user |
---|
72 | or group to zero on the specified printers. |
---|
73 | The life time page counter is kept unchanged. |
---|
74 | |
---|
75 | -R | --hardreset Resets the actual and life time page counters |
---|
76 | for the user or group to zero on the specified |
---|
77 | printers. This is a shortcut for '--used 0'. |
---|
78 | |
---|
79 | -s | --skipexisting In combination with the --add option above, tells |
---|
80 | edpykota to not modify existing print quota entries. |
---|
81 | |
---|
82 | -S | --softlimit sl Sets the quota soft limit to sl pages. |
---|
83 | |
---|
84 | -H | --hardlimit hl Sets the quota hard limit to hl pages. |
---|
85 | |
---|
86 | -I | --increase v Increase existing Soft and Hard limits by the value |
---|
87 | of v. You can prefix v with + or -, if no sign is |
---|
88 | used, + is assumed. |
---|
89 | |
---|
90 | -U | --used u Sets the page counters for the user u pages on |
---|
91 | the selected printers. Doesn't work for groups, since |
---|
92 | their page counters are the sum of all their members' |
---|
93 | page counters. |
---|
94 | Useful for migrating users from a different system |
---|
95 | where they have already used some pages. Actual |
---|
96 | and Life Time page counters may be increased or decreased |
---|
97 | if u is prefixed with + or -. |
---|
98 | WARNING : BOTH page counters are modified in all cases, |
---|
99 | so be careful. |
---|
100 | NB : if u equals '0', then the action taken is |
---|
101 | the same as if --hardreset was used. |
---|
102 | |
---|
103 | user1 through userN and group1 through groupN can use wildcards |
---|
104 | if the --add option is not set. |
---|
105 | |
---|
106 | examples : |
---|
107 | |
---|
108 | $ edpykota --add john paul george ringo |
---|
109 | |
---|
110 | This will create print quota entries for users john, paul, george |
---|
111 | and ringo on all printers. These print quota entries will have no |
---|
112 | limit set. |
---|
113 | |
---|
114 | $ edpykota --printer lp -S 50 -H 60 jerome |
---|
115 | |
---|
116 | This will set jerome's print quota on the lp printer to a soft limit |
---|
117 | of 50 pages, and a hard limit of 60 pages. Both user jerome and |
---|
118 | printer lp have been previously created with the pkusers and pkprinters |
---|
119 | commands, respectively. |
---|
120 | |
---|
121 | $ edpykota -g -S 500 -H 550 financial support |
---|
122 | |
---|
123 | This will set print quota soft limit to 500 pages and hard limit |
---|
124 | to 550 pages for groups financial and support on all printers. |
---|
125 | |
---|
126 | $ edpykota --reset jerome "jo*" |
---|
127 | |
---|
128 | This will reset jerome's page counter to zero on all printers, as |
---|
129 | well as every user whose name begins with 'jo'. |
---|
130 | Their life time page counter on each printer will be kept unchanged. |
---|
131 | You can also reset the life time page counters by using the |
---|
132 | --hardreset | -R command line option. |
---|
133 | |
---|
134 | $ edpykota --printer hpcolor --noquota jerome |
---|
135 | |
---|
136 | This will tell PyKota to not limit jerome when printing on the |
---|
137 | hpcolor printer. All his jobs will be allowed on this printer, but |
---|
138 | accounting of the pages he prints will still be kept. |
---|
139 | Print Quotas for jerome on other printers are unchanged. |
---|
140 | |
---|
141 | $ edpykota --delete --printer "HP*,XER*" jerome rachel |
---|
142 | |
---|
143 | This will delete users jerome and rachel's print quota |
---|
144 | entries on all printers which name begin with 'HP' or |
---|
145 | 'XER'. The jobs printed by these users on these printers |
---|
146 | will be deleted from the history. |
