---|
[728] | 160 | |
---|

| 162 | |
---|
| 163 | -v | --version Prints warnpykota's version number then exits. |
---|
| 164 | -h | --help Prints this message then exits. |
---|
| 165 | |
---|
[866] | 166 | -u | --users Warns users over their print quota, this is the |
---|
| 167 | default. |
---|
[728] | 168 | |
---|
[934] | 169 | -g | --groups Warns users whose groups quota are over limit. |
---|
[728] | 170 | |
---|
| 171 | -P | --printer p Verify quotas on this printer only. Actually p can |
---|
| 172 | use wildcards characters to select only |
---|
| 173 | some printers. The default value is *, meaning |
---|
| 174 | all printers. |
---|
[1156] | 175 | You can specify several names or wildcards, |
---|
| 176 | by separating them with commas. |
---|
[728] | 177 | |
---|
| 178 | examples : |
---|
| 179 | |
---|
| 180 | $ warnpykota --printer lp |
---|
| 181 | |
---|
| 182 | This will warn all users of the lp printer who have exceeded their |
---|
| 183 | print quota. |
---|
| 184 | |
---|
| 185 | $ warnpykota |
---|
| 186 | |
---|
| 187 | This will warn all users who have exceeded their print quota on |
---|
| 188 | any printer. |
---|
| 189 | |
---|
[1041] | 190 | $ warnpykota --groups --printer "laserjet*" "dev*" |
---|
[728] | 191 | |
---|
[1041] | 192 | This will warn all users of groups which names begins with "dev" and |
---|
| 193 | who have exceeded their print quota on any printer which name begins |
---|
| 194 | with "laserjet" |
---|
| 195 | |
---|
[1785] | 196 | If launched by an user who is not a PyKota administrator, additionnal |
---|
| 197 | arguments representing users or groups names are ignored, and only the |
---|
| 198 | current user/group is reported. |
