Issue with running generate_hcl.sh from ubuntu OS

Hello, We are trying to run ./generate_hcl.sh without adding any new variables. The generate_hcl.sh is compiling successfully, but its changing the state of variables even when there are no changes. 

When we run this from MacOS, we see no issues. The issue is occuring only from ubuntu OS. Can you confirm if ./generate_hcl.sh can be run from ubuntu OS ?
