    Update cli_checkFiles.sh. Apply to one file only. If you need to apply
    this function to many files, create a list of files and use this
    function inside a for structure. If the file exists, this function
    returns 0, and when file doesn't exist this function returns 1.
    
    This return value is useful to make verifacations based on whether the
    file checked exist or not.
