Projects / uschedule


uschedule is a job scheduler aimed to replace cron and at. It is secure by design. Unsafe concepts like set-user-id and set-group-id files and programs, communication between programs of different privilege levels, etc. have been removed.

            is this really GPL ?
            looking at version 0.7.1 I can't find any license information. Is this really GPL software ?

            Suggestion for addition to docs
            After installing uschedule according to the docs, I tried adding/deleting jobs. I found that the uschedulerm command kept failing with the message "could not open_write fifo: device not configured". It took me a long time looking through the source, but it turns out that the answer is that the uscheduled daemon was not running.

            You might want to add a mention to the installation docs that tells people to start the uscheduled daemon before trying to use the programs.
