Gleb Smirnoff a08d12d3f2 Add new functionality and syntax to cron(1) to allow to run jobs at a ... given interval, which is counted in seconds since exit of the previous invocation of the job. Example user crontab entry: @25 sleep 10 The example will launch 'sleep 10' every 35 seconds. This is a rather useless example above, but clearly explains the functionality. The practical goal here is to avoid overlap of previous job invocation to a new one, or to avoid too short interval(s) for jobs that last long and doesn't have any point of immediate launch soon after previous run. Another useful effect of interval jobs can be noticed when a cluster of machines periodically communicates with a single node. Running the task time based creates too much load on the node. Running interval based spreads invocations across machines in cluster. Note that -j/-J won't help in this case. Sponsored by: Netflix		2018-06-07 22:38:40 +00:00
