How do I run a Shell Script/shell commands within C++?| lazyrussian (7) |  |
| Hi, I'm somewhat of a beginner at C++ (only been around OOP for 6 months or so now - started with Java). Anyway, with that being said, I hope someone can write a simplified answer to my problem or point me to a page with an answer for this. Problem: I need to have C++ script execute a set of shell commands (tcsh and/or bash environment) on a machine running Ubuntu or Fedora Core. The user will launch a graphical interface (written in C++) from the shell, and within there, he/she will utilize an option that performs a task within the shell, using shell commands. So I need to program this new option in C++ (to incorporate it into the C++ GUI system), but the commands I want to run need to be written in shell script. Thanks in advance for any and all help! | |

| To start a new process off you would usually use a fork() followed by one of the exec() family of calls. I should point out that most shell commands have a 'C' code API equivalent. There are very few occasions when something cannot be done in C/C++. | |

| Much as I hate language war threads... If you are just starting you might want to check out Tcl/Tk. It is designed specifically to do the kinds of things you want to do. http://wiki.tcl.tk/ Chances are it is already available on your system and your customers' systems. If you are already bound to C++ then ignore me. :-) | |

| Thank you both for the reply. I ended up getting most of my goals achieved witht he System() command function :) Now, I have a new problem that arose. So, via the shell (and within my C++ script) I need to launch ROOT (C++ Framework for Physicists) and run a few commands in ROOT. I can launch root just fine with system(root), but how do I run root-specific commands through my C++ program - is it possible? Thanks! | |
