Hi all,
I am writing a script that would take some user input but I want to make sure that the string provided by the user is consistent.
Is there a way to transform a string in bash to all lower case or all upper case?
Thanks!

Hi there,
There are multiple ways of doing it, but what I personally use is the following syntax:
echo "${user_input_variable,,}"
echo "${user_input_variable,}"
echo "${user_input_variable^^}"
echo "${user_input_variable^}"
Here is a quick demo:
Hope that this helps! Regards, Bobby
