You cannot use the 'pipe command' to bcp data out of a sybase server.
You have to use a named pipe.

Do something like this:

Create a named pipe:

mknod /tmp/bcp-pipe p

Start a bcp-session:

bcp mydb..mytable out /tmp/bcp-pipe -c -Uuser -Sserver
[download]

And then you can read from that pipe in your perl program:

open FIFO, '/tmp/bcp-pipe' or die "cannot open /tmp/bcp-pipe: $!\n";
while (<FIFO>) {
  print "bcp-data: $_";
}
close FIFO;
