Is there a way to flush the buffer that nohup buffers stdout? From what I read in various places (eg. some place) is that I can modify the behaviour from within my programm. But that would be specific to each programm, and there are some where I would not want to mess with the code.

So I am looking for a general way to tell a 'nohuped' programm to flush stdout. Something on the commandline likeflush sdtout <PID>. Is there something like that? Or some sort of workaround?

  • What kind of output does your program generate? (Line oriented with trailing newline?) What OS and programming language do you use? – MattBianco Sep 16 '10 at 14:21
  • Line oriented with trailing newline. OS Linux, programming langue varies: bash, perl, python ... I was looking for something independent of the used language, but maybe I am on the wrong track there. – Isaac Sep 16 '10 at 14:58

It's possible the (deceptively simple) unbuffer script that comes with expect may do what you're looking for.

  • Thank you, that is pretty much what I was looking for. Very helpfull! – Isaac Sep 17 '10 at 13:59
  • So, would it be like nohup unbuffer script.sh &? – István Zachar Aug 14 '14 at 6:41
