Thread: Execute a command from C code in a different terminal

Hi,

I want to write a C program that can launch an executable in a new shell different from the controlling shell. So what I did is :

1) Used the system("gnome-terminal") function to launch a new shell
2) Opened it as file using its tty name (like : /dev/pts/<> )
3) wrote something like : fwrite("./hello\n", sizeof("./hello\n"), 1, fp);

I got a new terminal, it opened like a file, fwrite() was also done but './hello' did not work like a command. It stood there like a dead text.

Please help!!!!

Nope sorry that's not going to work...

C programs require compilation before they will run.

I did not get you.
I have compiled my C program and then executed it, that's how I told that whats happening and as far as the binary 'hello' is considered..it is also present...

Try something like print the current directory command (I can not remember the Linux/Unix command for that.)

It is likely the new shell has a different current directory than the one you think it has.

Code:
