within a shell command file to read from your terminal. The line command always writes at least a newline character.

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.
