cron vs. whenjobs vs. goaljobs in Linux

Question

I'm interested in a replacement for cron which would allow me to run various cron jobs on demand, and mark them as having been run, so they won't be run again from the schedule.

I noticed whenjobs, which looks like it may do the job. The documentation for whenjobs says that it is obsolete and has been replaced by goaljobs.

Has anyone tried out whenjobs or goaljobs.

Answer 1

Two key advantages of Whenjobs over cron are a simpler syntax for writing rules and a powerful dependency system that lets one job depend on variables set when other jobs run (allowing, for example, one job to run only when another job has finished successfully).

Instead you must use this style:

whenjobs --set variable=value

You may need quoting if the value contains a space. If you are using the optional --type parameter, put it before the variable=value declaration.
