And don't run the two test too soon after eachother, your operating system will cache some data. Also run all the tests multiple times. Wijnand -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: two way piped open

Makes sense, but that's not it, unfortunately. I tried it and it still hangs... Also, strangely, with the two "\n"s, the next time I try to write to the filehandle it says the pipe is broken. Here's sample output from the tool: ** ralph 2104% yprtool -l 90

RE: two way piped open

Just a thought, but this behavior might be caused by Perl buffering your output. Try selecting your file handle and then setting $| to 1. That way Perl should send your output immediately. -Original Message- From: Bryan R Harris [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 24

Re: two way piped open

And a follow-on question: Any idea why I have to send the yprtool two "\n"s instead of one to make it work? With just one it hangs... On the command line, it definitely works with just one. ** ($y,$p,$r) = (split(' ', $lines[15]))[11..13]; use IPC::Open2;

I'd like to open 2-way pipe to a tool that we have here. It's called yprtool and once it's open, you give it 3 numbers to its STDIN and it spits out 3 numbers to its STDOUT. It stays open until you ctrl-c it. What's the correct syntax for opening something like this? This doesn't work: *
