If they exist, they are modified unless -s|--skipexisting is also used. -d | --delete Deletes billing codes from PyKota's database. NB : the history entries with this billing code are not deleted, voluntarily. -D | --description d Adds a textual description to billing codes. -l | --list List informations about the billing codes. -r | --reset Resets the billing codes' balance and page counters to 0. -s | --skipexisting In combination with the --add option above, tells pkbcodes to not modify existing billing codes. code1 through codeN can contain wildcards if the --add option is not set. examples : $ pkbcodes --add -D "My project" myproj Will create the myproj billing code with "My project" as the description. $ pkbcodes --delete "*" This will completely delete all the billing codes, but without removing any matching job from the history.
