Hi everyone,

I'm writing a program in which I use the "system" system call.
(We use 4.3BSD)

I use it like this

extern int system();
int err;

err=system("mail -s subject user < file");


When I compile and run this program (of course this is not the
complete program) it executes the call perfectly but also
generates the error message :

Unknown command: "################################################"

What does this mean and does anyone know how to solve this ?
Normally it is no problem because it works OK but I want to use
the program in CRON and I don't want this message to appear every
15 minutes or so on the console.

Who can help me ?

Thanks,
