Sometime it is necessary to read one line from a file or keyboard. We have Shell script utility to read a file line by line here and here. However, you can use line command to do same thing.
For example, read one line from keyboard and store to variable called na:
$ na=$(line)
Howdy Guest
$ echo $na
Output:
Howdy Guest
The utility line copies one line (up to a newline) from standard input (keyboard) to standard output (screen). It always prints at least a newline and returns an exit status of 1 on EOF or read error.
You can easily use line command in a shell scripts.
