Re: Shell scripts, fglgo & interrupt

I use the following trival piece of C code to do the job, in conjunction with the script: trap "" 2 3 while : do iqon fglgo test done Note that the C code should really include <unistd.h> to pick up the declaration of execvp(), and <stdlib.h> for exit(), and it should use EXIT_FAILURE in place of 1 in the call to exit(). Equally, I haven't changed it in a while, as you can also see from the last changed date...
