awk being one of the powerful commands that even has the capability of performing data science in bash. But here in a simplistic usage, we would count the length of the string. Syntax: `echo $string_name | awk '{print length}'`
In the rare case of us having to make a distinction between "being set to an empty string" vs "not being set at all", we could use these: if [[ ${var+x} ]]; then # var is set but it could be empty if [[ ! ${var+x} ]]; then # var is not set if [[ ${var+...
