In this article I will provide you the bash script code to convert your strings to all lowercase. We require this functionality a lot like when storing usernames, emails, url slugs etc. Case sensitive data can create errors and that’s why we keep some data in lowercase only.
Code Example –
#!/bin/bash
lower() {
echo "${1,,}"
}
lower "AN animAl is aN animal. DONKEY or DOG does NoT mAtTeR"
# Output:
# an animal is an animal. donkey or dog does not matter
