well spotted. I was wondering about the loop in the test though. Can the `kill -0` ever fail. Even if that's not redundant I'm not sure the file is guaranteed to be written at this stage? How about: diff --git a/tests/tail-2/flush-initial b/tests/tail-2/flush-initial index 2deff84..378440c 100755 --- a/tests/tail-2/flush-initial +++ b/tests/tail-2/flush-initial @@ -28,10 +28,11 @@ echo line > in || fail=1 stdbuf --output=1K tail -f in > out & tail_pid=$! -# Wait for the backgrounded `tail' to start. -while :; do - env kill -0 $tail_pid && break - sleep .1 +# wait for a second for the file to be flushed +count=0 +until test -s out -o $count = 10; do + count=$((count+1)) + sleep .1 done test -s out || fail=1 cheers, Pádraig.
