To print the message in quotes, you can use the
%q format specifier (see the fmt docs).
You'll want to convert your buffer to a string and make sure you only use the part of the buffer that contains data (up to
// buf[:reqLen] is a slice of the first reqLen bytes of buf. // string(...) creates a string from a slice of bytes. fmt.Printf("Message contents: %q ", string(buf[:reqLen]))
This will print:
Message contents: "message "
echo. If you don't want it, run
echo -n ..., or strip surrounding whitespace/newlines using strings.TrimSpace.
