Read command – The read command allows you to prompt for input and store it in a variable. shell allows to prompt for user input.
Syntax:

or
read –p “prompt” varname [more vars]

Is shell relevant in 2017?

Shell is very relevant. It is used to boot up almost any application that you run on a linux server. Any time a linux server is restarted, you then use shell scripts to restart any applications running on that server. Also, cron jobs running on a linux server call shell scripts for starting/restarting applications.

Shell will be relevant while a Shell based OS is relevant!! And that is likely for the next few decades!
