Read User Input Example

#! /bin/bash

echo "Enter name : "
read name
echo "Enterd name : $name"

• Multiple inputs

echo "Enter names : "
read name1 name2 name3
echo "Names : $name1 , $name2, $name3"

• Two commonly used options however are
• -p which allows you to specify a prompt
• -s which makes the input silent.

read -p 'username : ' user_var
read -sp 'password : ' pass_var
echo
echo "username : $user_var"
echo "password : $pass_var"

• -a makes read command to read into an array

echo "Enter name : "
read -a names
echo "Names : ${names[0]}, ${names[1]}"

• read command will now store the reply into the default build-in variable $REPLY

echo "Enter name : "
read 
echo "Name : $REPLY"

• default variable

echo "Enter name: "
read
echo "Name : $REPLY"
