When I want to use cron to run a task more frequently than once per minute, my trick is to have the target program perform the task more than once per invocation. E.g.:<p><pre><code> # script start, T=0s
do_something()
for n in range(0, 11):
time.sleep(5)
do_something()
# script end, T=55s</code></pre>
