Hi,
Can someone explain this for me.I dont know Unix and so am finding problem in understanding pipe concepts.Moreover I am very new to perl and Unix.Got this piece of code from perldoc

open(SPOOLER, "| cat -v | lpr -h 2>/dev/null")
            || die "can't fork: $!";
    local $SIG{PIPE} = sub { die "spooler pipe broke" };
    print SPOOLER "stuff\n";
    close SPOOLER || die "bad spool: $! $?";

[download]

Can someone suggest a good site which explains the basics and advanced concepts in files in a very simple manner. perldoc does not provide much of information.
Thanks in advance
