Subject: [PATCH] nfsiostat: periodically flush stdout
Date: Tue, 10 Sep 2013 03:17:30 +1000	[thread overview]
Message-ID: <1378747050.4117.122.camel@serendib> (raw)

* In a shell script, when nfsiostat is run in the background with
  stdout redirected to a file, flush stdout periodically to ensure
  that we do not lose the buffered output if the nfsiostat process 
  is killed.
