None
DESCRIPTION
The line command copies one line, up to and including a newline, from standard input and writes it to standard output. Use this command
within a shell command file to read from your terminal. The line command always writes at least a newline character.
NOTES
The line utility has no internationalization features and is marked LEGACY in XCU Issue 5. Use the read utility instead.

Success. End-of-File.
EXAMPLES
To read a line from the keyboard and append it to a file, enter: echo 'Enter comments for the log:' echo ': c' line >>log
This shell procedure displays the message: Enter comments for the log:
It then reads a line of text from the keyboard and adds it to the end of the file log. The echo ': c' command displays a : (colon)
prompt. See the echo command for information about the c escape sequence.
