printf "%s\n" "$4"

    Write arguments to the standard output.
    
    Display the ARGs, separated by a single space character and followed by a
    newline, on the standard output.
    
    Options:
      -n        do not append a newline
      -e        enable interpretation of the following backslash escapes
      -E        explicitly suppress interpretation of backslash escapes
