$ mkfifo /var/tmp/foo $ buffer -i /var/tmp/foo # misc/buffer # in another console: $ echo hi > /var/tmp/foo buffer prints hi and exits. I want it to keep reading and printing indefinitely. Further experimentation revealed that I need two writers: one dummy writer that just keeps /var/tmp/foo open for writing, and the other doing the "real work". This way buffer wouldn't exit. But how to emulate the dummy writer? It itself needs to block on something to keep /var/tmp/foo open. Any clean way to do this in shell? Maybe the solution is quite simple but isn't at the tip of my tongue. Thanks.
