In a shell script, run proga and progb in the background, then wait
for them both with the "wait" builtin.  Something like this:

    #!/bin/sh -e
    # -e flag will abort on any error
    proga &    # Start proga in background
    progb &    # Start progb in background
    wait       # Wait for whichever finishes first
    wait       # Wait for the other one
    progc      # Now run progc in the foreground
