Watch without watch

Heres a little bash script to do what watch does without having to install watch

Start by creating watch.sh

#!/bin/bash

while true; do
    clear
    $2
    sleep $1  # adjust interval as needed
done

make sure to set the permissions to be able to execute

chmod a+x watch.sh

execute with

./watch.sh 2 "du -h -d 1"

where the first parameter is interval in seconds and the second is the command wrapped in double quotes
