I have a matlab script that I run from the terminal, that script creates an instance of another program using:



system('cd <path> && mpiexec -n 1 ./<program2> &')


Problem is I don't see any terminal output from program2. (It works if I omit the ampersand, but I need program2 to run in the background). Is it possible to have both the matlab script and program2 output to the same terminal?




terminal background-process io matlab

  • Hmm, it's not clear at all what MATLAB does if anything with the output from system('cmd&'); I suspect you'll need to find a different way to solve this problem.

  • Perhaps you can add >&/dev/tty to the mpiexec command to make it output to the terminal.

  • @meuh It didn't work. Still no output in terminal. Output works fine if I direct it to a logfile though... '.... ./<program2> > logfile 2>&1 &'
