I'm new to shell scripting.

I'm trying to somehow cron a job that will wget one url once to trigger a task, and another url every 2 minutes after to keep the task alive.

So far I've managed to get the first url to work without issue, the problem comes with the second url wget repeating every 2 minutes for 1 hour.

I've tried including cron within the .sh script as I saw suggested somewhere else, like

*/2 * * * * wget $url

but terminal just throws it out with an error "no such file or directory".

Whats the best method of doing this?

As @Fiximan and @steeldriver suggested, another option is to run wget in a loop for 1 hour:

COUNT=0

while [ $COUNT -lt 30 ]; do

  wget $url

  sleep 120

  COUNT=$((COUNT + 1))

done

Note that script containing this code must be run using #!/bin/bash, not #!/bin/sh.
