The line utility copies one line (up to and including a new-line) from the standard input and writes it on the standard output. It returns an exit status of 1 on EOF and always prints at least a new-line. It is often used within shell files to read from the user's terminal.

Exit status is:

0

Successful completion

>0

End-of-file on input.
