How do you use chmod inside a shell script

Question

So this is in a shell script:

#!/bin/bash
trialName= "trial.txt"

chmod a+rwx $trialName

That doesn't really work. I am trying to add single quote/double quotes around $trialName but that doesn't work either. Any way I can do that?

Answer 1

You need to remove the space after the =:

trialName="trial.txt" # note the absence of the space between '=' and '"'
chmod a+rwx "$trialName"
