Cannot check runs

I'm trying to get the script to run and quiet down my noisy fan.
The script downloaded ok to /etc but I cannot check that it runs and see the following when running verbose from the /etc directory.
Any ideas where I'm going wrong?

root@OpenWrt:/etc# chmod +x
root@OpenWrt:/etc# verbose
-ash: not found
root@OpenWrt:/etc# ls
