Write a non-buffering stage to preceed the sed stage.command | non-buffering-counter | sed-stage | command2 The non-buffering counter stage immediately passes each input to its output (does not buffer [stack] the data) and also keeps a running total of bytes/words that can be posted to a log file at convenient intervals of mbs.
dd might be non-buffering if you set it low-enough blocksize. something like: command | dd bs=1b | sed-stage | command2 Then if you can figure out how to get the pid for dd. (ie. I don't know how to get the pid of a command in the middle of a pipe call like that. Maybe after the fact via ps -ef | grep | cut ...) You can have a loop that tells dd to give a status update every 10 minutes or so: while true do sleep 600 kill -sigusr1 $dd_pid done None of this is tested but you get the idea.
