Question

language: Unix/Linux

myName = John Doe

Exercise 6 Write an executable script that reads a value from the keyboard and store it to myClass variable. And then export the variable myClass so that commands executed in any child shell have access. Exercise 7 Copy the value of myName variable to another variable, anyName. Verify that it copies correctly. Then unset both the myName and anyName variables. Show their new values

Answer 1

Exercise 6 -:- NOTE :- read command reads the value from the keyboard and store it in myClass variable and export command will make the variable available for the child shells also otherwise by default all the variables are local to a shell

#!/bin/bash

read -p "Enter the value : " myClass
export myClass
