I have a basic inotifywait script called watch.sh and a few files ending in .styl in the same directory. Here's the script, that catches the changes, but doesn't execute the code within the do/done

I init it like sh watch.sh and here's the script

#!/bin/sh

while inotifywait -m -o ./log.txt -e modify ./*.styl; do
  stylus -c %f
done

I tried having echo "hi" within the exec portion but nothing executes
