Description
The line command copies one line (up to and including a newline) from the standard input and writes it on the standard output. It returns an exit status of 1 on end-of-file and always prints at least a newline. It is often used within shell files to read from the user's terminal.
Examples
When you invoke the line command, it enters a newline and waits for you to type a line. When you press Return, the line is echoed to standard output, as shown in the following example.
