snooze

Run a command at a particular time

Snooze waits until a particular time and then runs a command. Together with a service supervision system such as runsv(8) (from sysutils/runit), this can be used to replace cron(8). Benefits over cron(8): - mnemonic syntax - no overlapping job runs possible - filtering by ISO week and day of year - no centralized daemon required (no fuzzing with multiple users/permissions) - can easily disable jobs or force their execution instantly - have custom logs - very robust with respect to external time changes - can use a file timestamp to ensure minimum waiting time between two runs, even across reboots - randomized delays - variable slack - ad-hoc usage possible, just run the program from command line
