Bash cómo convertir el texto en minúsculas o mayúsculas
# Basic syntax:
tolower(string)
toupper(string)
# Example usage:
awk '{print tolower($0)}' input_file
# This prints every row ($0) converted to lowercase
awk '{print toupper($3)}' input_file
# This would print the third field ($3) converted to uppercase
