How can I execute a command inside ROOT that I launch within the bash script? My aim is to have ROOT execute its GUI file browser and have it open if the user does not interfere with keyboard commands. I tried but failed since the GUI file browser stays open for a really short period of time. Is it possible that I modify the bash script and have the program open when the script terminates?

The description of ROOT can be found in the following link:

Yes, a program can execute another program. What program is it? Your question is as vague as “can I drive a car on a road”. What is your actual question? –  Gilles Aug 1 at 22:04
    
@Gilles I edited the question for clarity, thanks for pointing out the ambiguity. –  Vesnog Aug 1 at 22:17
    
Your question is still unclear. If program A has a command prompt, type the command at the command prompt. You seem to be running into some kind of problem, but you need to tell us what that problem is. –  Gilles Aug 1 at 22:19
    
@Gilles Yes program A has a command prompt and I invoke the command by using the construct EOF, but when program A is closed without my interference and I would like to have it open as much as I please. Thanks for your interest by the way. –  Vesnog Aug 1 at 22:26
    
It seems that program A is doing something peculiar. What is program A? You need to give us the information! –  Gilles Aug 1 at 22:46

just type the command and it will be executed:

#!/bin/bash
ls -l

if you want to run other shell scripts use:

sh otherShell.sh

or for executable files:

. otherShell.sh

gnuplot is as other commands, you can use it inside shell script:

Example:

#!/bin/sh
lib=$1
old="output/old/$lib.dat"
new="output/new/$lib.dat"

gnuplot << EOF
set logscale x
set logscale y
set size square
set grid
set pointsize 1
plot "< paste $old $new" using 1:4 ti '$lib'
EOF

for the problem "it was giving no time for view and interaction with the GUI launched within the application": you can tell gnuplot to print the plot to file, which you can open up and view yourself:

plot '<SOME FILE>' .......

Or you need to invoke gnuplot with a flag:

gnuplot --persist

to ensure that plots stay up after gnuplot quits.

My point is that I will launch an application with the command say GNUplot ,it will be ROOT Data Analysis Framework in my case, and pass some command to be executed inside GNUplot. –  Vesnog Aug 1 at 22:05
    
Thanks for the edit it will be helpful, I think this will also work with other programs. –  Vesnog Aug 1 at 22:09
    
@Vesnog Yes as I know. –  Networker Aug 1 at 22:10
    
It works as intended but the application is closed immediately, giving no time for view and interaction with the GUI launched within the application(ROOT). –  Vesnog Aug 1 at 22:23
    
@Vesnog, see Updates –  Networker Aug 1 at 22:34
