How can I split input using bash?

I have to write a script in Linux, that takes input from user.

For example, this could be a line of input:

name = Ruba

I need to take the "Ruba" from the input, so how can i split the input and take the last part?

You can use IFS in bash, which is the "internal field separator" and tells bash how to delimit words. You can read your input in with IFS set to a space (or whatever delimiter) and get an array back as input.

#!/usr/bin/env bash

echo "Type in something: "

# read in input, using spaces as your delimiter.
# line will be an array
IFS=' ' read -ra line

# If your bash supports it, you can use negative indexing
# to get the last item
echo "last item is: ${line[-1]}"

Test run:

$ ./inscript.sh 
Type in something: 
name = ruba
last item is: ruba

If you want to read name:

#!/bin/bash
read -p "Name: " name
echo $name

The code above prompts for name and output it.

If your input is "name = Ruba"

#!/bin/bash
read name
name=$( echo $name | sed 's/.*=\ *//' )
echo $name

The code above read a line like "name = Ruba" and remove all characters preceding = and spaces after =.
