SYNTAX
line
DESCRIPTION
Line copies one line (up to a new-line) from the standard input
and writes it on the standard output. It returns an exit code 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.

EXAMPLES
This example is a shell program that gathers information about
users.
$ echo "ENTER YOUR NAME"
$ NAME=`line`
$ echo "ENTER YOUR DEPARTMENT NUMBER:"
$ DEPT=`line`
$ echo "$NAME $DEPT" >> personnel
First, the program queries you for your name. Because line is
surrounded by grave accents, the program executes it, and line
reads the name and assigns the name to the variable "NAME". Then
the program asks for your department and office extension. The
program assigns these values to "DEPT" The last line appends
"NAME"and "DEPT" to the file "personnel".
