Hello,
Wouldn't it be a good idea to implement an optional expiry date when adding cronjobs in webmin? Webmin could periodically check all cronjobs and *delete* those who expired. This would be useful, if you have (many) cronjobs that should run a certain period of time only, e. g. cronjobs which run test-scripts.
Up to now you can specify a deadline; according to this the cronjobs will be disabled then. My idea is to add a checkbox like "Delete cronjob on expire".
P.S.:
Can you make the command being multiline, so that you can also rite small scripts as cronjobs? It's hard to read a long command consist of many &&'s...
P.P.S:
Beginners (like me) might wonder, why some commands won't work. Beging able to set a current working dir for the command would be a convenient thing.
If you want only a few instances of scheduled job, you probably want the at command.
As far as multi-line commands, that's a cron limitation - not a webmin limitation. :)
