Hi Albert,

Strictly speaking, it's not a pipe but a redirection.  It is
handled by the shell, not the OS (unless the shell is built into
the OS).

However, judging from the web site it looks like Probcons is a
Unix program.  This makes you concern somewhat unnecessary.  A
few lines further down, you also add a redirection of stderr to
/dev/null.  This would prevent the user from seeing any errors
produced by the probcons executable, which is bad since it will
mean that the user would be unaware of them.  In general, I
believe in letting the user decide what to see or not see.


Regards,
Andreas
