What is snooze

snooze is:

snooze is a tool for waiting until a particular time and then running a command. Together with a service supervision system such as runit, this can be used to replace cron(8).

Benefits over cron:

• mnemonic syntax
• no overlapping job runs possible
• filtering by ISO week and day of year
• due to supervision, no centralized daemon required
• due to supervision, can easily disable jobs or force their execution instantly
• due to supervision, have custom logs
• due to no centralized daemon, no fuzzing with multiple users/permissions
• 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 (some cron have that)
• variable slack (no need for anacron)
• ad-hoc usage possible, just run the program from command line

Benefits over runwhen:

• less confusing usage (arguably)
• filtering by ISO week and day of year
• zero dependencies

Benefits over uschedule:

• no centralized daemon required
• filtering by ISO week and day of year
