Apr 15	comment	How to duplicate a stream and process both parts in a streaming way? I discovered this just this afternoon, by coincidence. Thanks!

Apr 15	comment	Can't process stdout with pipe as it comes Great trick, but stdio buffering exists for a good reason, and it's lame that utilities which mess with stuff like `isatty()` force you to do this.
Apr 15	comment	Can't process stdout with pipe as it comes Yo may need to put the entire command in quotes. Gets tricky with such a complex command. Try putting your entire call to tshark in a shell script, and then doing `script -c myscript.sh`.

Apr 14	comment	local email storage syncing to imap - mutt-friendly Thanks. I found isync, now named absync. It's working well!
Apr 14	comment	How to duplicate a stream and process both parts in a streaming way? If performance is crucial and the process you want to run is fairly trivial, you could reimplement (for example) a version of `wc` that prints its result to stderr, and ensures that every byte from stdin comes out of its stdout. Beware, though, that an architecturally more 'efficient' implementation may be slower anyway as coreutils and sed/awk are heavily optimised for many tasks.

Mar 24	comment	Races when piping two commands to a named pipe From the point of view of simplicity, there is nothing broken about the read side. In practise I will connect this pipe to the stdin of a process that does some stream processing and writes stuff out; EOF on STDIN is EOF on STDIN.
Mar 24	comment	Races when piping two commands to a named pipe I understand this; the issue that I have is that cat is seeing EOF on the pipe in the first place. I need to control the behaviour so that i can redirect the output of N processes to the write end of the pipe before it's closed (ie before the reader, in this case cat, sees EOF).

Feb 20	comment	Managing the output streams of many subprocesses with deadlocks Thanks, a select() loop on stderr is actually perfect for what I'm trying to do - as long as I make sure I don't close stderr in the child processes before they exit.

Feb 9	comment	Managing the output streams of many subprocesses with deadlocks I'm looking at the retcode to decide whether it failed, but I need the stderr to get the log output and send it off or propagate the error reporting.
