In POSIX compatible shells, `echo '/n'` prints simply /n. printf is the shell function which interprets escape sequences, like \\n, \\t, \\r, etc. `echo`, without any arguments, prints a new line, which is what you want. Hence, for clarity's sake: printf '\\n' | ontape -s -L -0 Which is really unnecessary, since we have `echo`.
