I have read so many answers and they all just suggest to kill the script or send it to the background etc. What I want is

while true do

something...

if(ctrl+c is pressed break)

done echo "Out of the loop"

I am outside the loop because ctrl+c was pressed and so I can do other stuffs here without exiting the script....

And this question is not a duplicate because I have searched for hours and no answer gives me what I want. That "Out of the loop" never gets printed, I tried so many examples from various answers !

Info: I use (1) Scientific Linux SL release 5.4 (Boron), (2) Ubuntu 16.04

Edit: I want this exact code to work

#!/bin/bash

loopN=0

while true
do

echo "Loop Number = $i"
i=$(($i+1))

#I want to break this loop when Ctrl+C is pressed

done

#Ctrl+C has been pressed so I am outside the loop going to do something..

echo "Exited the loop, there were $i number of loopsexecuted !"
#here I will execute some commands.. let's say date
date

#and then I will exit the script
