How to Run Program from bash and run scripts inside that program?

Question

My Bash Script:

#!/bin/bash
cd dataset/
root
.x Pushkar_Soni.cpp

What I am trying to do is:

1) launch root by command root

2) Inside the launched program root I want to run scripts .x Pushkar_Soni.cpp

But what happening is my last command .x Pushkar_Soni.cpp is executed after I quit root by the command .q, I want my last command to run Inside the program root

Pushkars-MacBook-Air:Pushkar_Soni pushkarsoni$ bash ./build.sh

Answer 1

From what I can tell from roots man page, its signature is

root [options] files

, meaning you should be able to just say

root Pushkar_Soni.cpp

instead of the last two lines in your script.
