Positive or 69 negative floating point values are allowed, 70 this allows you to do some really creative 71 things like giving money to an user whenever 72 he prints. The number of pages in a print job 73 is not modified by this coefficient, only the 74 cost of the job for a particular user. 75 Only users have such a coefficient. 76 77 -i | --ingroups g1[,g2...] Puts the users into each of the groups 78 listed, separated by commas. The groups 79 must already exist in the Quota Storage. 80 81 -L | --list Lists users or groups. 82 83 -l | --limitby l Choose if the user/group is limited in printing 84 by its account balance or by its page quota. 85 The default value is 'quota'. Allowed values 86 are 'quota' 'balance' 'noquota' 'noprint' 87 and 'nochange' : 88 89 - quota : limit by number of pages per printer. 90 - balance : limit by number of credits in account. 91 - noquota : no limit, accounting still done. 92 - nochange : no limit, accounting not done. 93 - noprint : printing is denied. 94 NB : nochange and noprint are not supported for groups. 95 96 -b | --balance b Sets the user's account balance to b. 97 Account balance may be increase or decreased 98 if b is prefixed with + or -. 99 WARNING : when decreasing account balance, 100 the total paid so far by the user is decreased 101 too. 102 Groups don't have a real balance, but the 103 sum of their users' account balance. 104 105 -C | --comment txt Defines some informational text to be associated 106 with a change to an user's account balance. 107 Only meaningful if -b | --balance is also used. 108 109 110 -r | --remove In combination with the --ingroups option above, 111 remove users from the specified users groups. 112 113 -s | --skipexisting In combination with the --add option above, tells 114 pkusers to not modify existing users. 115 116 user1 through userN and group1 through groupN can use wildcards 117 if the --add option is not set. 118 119 examples : 120 121 $ pkusers --add john paul george ringo/ringo@example.com 122 123 This will add users john, paul, george and ringo to the quota 124 database. User ringo's email address will also be set to 125 'ringo@example.com' 126 127 $ pkusers --ingroups coders,it jerome 128 129 User jerome is put into the groups "coders" and "it" which must 130 already exist in the quota database. 131 132 $ pkusers --limitby balance jerome 133 134 This will tell PyKota to limit jerome by his account's balance 135 when printing. 136 137 $ pkusers --balance +10.0 --comment "He paid with his blood !" jerome 138 139 This will increase jerome's account balance by 10.0 (in your 140 own currency). You can decrease the account balance with a 141 dash prefix, and set it to a fixed amount with no prefix. 142 A comment will be stored for this balance change. 143 144 $ pkusers --delete jerome rachel 145 146 This will completely delete jerome and rachel from the quota 147 database. All their quotas and jobs will be deleted too. 148 149 $ pkusers --overcharge 2.5 poorstudent 150 151 This will overcharge the poorstudent user by a factor of 2.5. 152 153 $ pkusers --overcharge -1 jerome 154 155 User jerome will actually earn money whenever he prints. 156 157 $ pkusers --overcharge 0 boss 158 159 User boss can print at will, it won't cost him anything because the 160 cost of each print job will be multiplied by zero before charging 161 his account. 162 163 $ pkusers --email @example.com 164 165 This will set the email address for each user to username@example.com 166 """) 37 167 38 168 39 class PKUsers(PyKotaTool) : … … 201 72 ugroup.addUserToGroup(user) 202 73 74 def sanitizeNames(self, names, isgroups) : 75 """Sanitize users and groups names if needed.""" 76 if not self.config.isAdmin : 77 username = pwd.getpwuid(os.geteuid())[0] 78 if isgroups : 79 user = self.storage.getUser(username) 80 if user.Exists : 81 return [ g.Name for g in self.storage.getUserGroups(user) ] 82 return [ username ] 83 return names 84 203 85 def main(self, names, options) : 204 86 """Manage users or groups.""" 205 names = self.sanitizeNames(options, names) 206 suffix = (options["groups"] and "Group") or "User" 207 208 if not options["list"] : 87 islist = (options.action == "list") 88 isadd = (options.action == "add") 89 isdelete = (options.action == "delete") 90 91 if not islist : 92 self.adminOnly() 93 94 names = self.sanitizeNames(names, options.groups) 95 if not names : 96 if isdelete or isadd : 97 raise PyKotaCommandLineError, _("You must specify users or groups names on the command line.") 98 names = [u"*"] 99 100 if options.remove and not options.ingroups : 101 raise PyKotaCommandLineError, _("You must specify users groups names on the command line.") 102 elif (((islist or isdelete) and (options.limitby \ 103 or options.balance \ 104 or options.email \ 105 or options.remove \ 106 or options.overcharge \ 107 or options.ingroups \ 108 or options.description \ 109 or options.skipexisting \ 110 or options.comment))) \ 111 or (options.groups and (options.ingroups \ 112 or options.balance \ 113 or options.email \ 114 or options.remove \ 115 or options.overcharge \ 116 or options.comment)) : 117 raise PyKotaCommandLineError, _("Incompatible command line options.
