edit comments

the edit invoked as

sh otsetup.sh

you invoking script sh , not bash.

the parameter substitution using put string lowercase

response=${response,,} # lower

is available using bash version 4.0

so either call script modern bash or use syntax not bash-dependant.

for example

response=$(echo "$response" | tr '[:upper:]' '[:lower:]')
