Re: capture STDOUT when some jerk opened STDOUT to /dev/tty

You can use screen(1) to capture the output sent to /dev/tty easily. For instance:

$ screen -L ssh foo.bar.com

Sure, rub it in that we don't get to have screen at $work ;_; You know I even tried `ssh 0 cmd`!! Using screen is a really cool idea though. Originally I was just wondering if there was an obvious Perl solution to the problem that I was just either overlooking or of which I was unaware.

Well, you can write your own tty logger using IO::Pty. It shouldn't be too complex. Another option may be to run the program through `strace` logging the interesting events. Then post-process that information to obtain a clean log of the data written to /dev/tty	[reply] [d/l]
