NAME

timer — run command at a specific interval

SYNOPSIS

DESCRIPTION

The timer utility runs command at every interval.

interval is a string containing non-negative decimal numbers including floats, terminated by suffixes: s for seconds, m for minutes, h for hours, d for days.
If the final number doesn't have a suffix, seconds are assumed. Longer durations are taken as out of scope.

If command exits with a non-zero status, timer exits with the same status, allowing to use service supervision to track failures.

EXIT STATUS

The timer utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

• Run munin-cron every 5 minutes: timer 5m munin-cron
• Print bell every minute and a half: timer 1m30s printf '\a'

SEE ALSO

at(1), crontab(1), sleep(1), timer_create(3)
