It seems that the shell was not happy aboutsomething.  At any rate, I made a few edits (including adding a missing argument to the doors benchmark) and things seem to run mostly ok now.  Inotice that the doors benchmark returns an error sometimes.  I also noticethat when running the bw_svmsg benchmark, the benchmark hangs if xfersize isset greater than 2048 (a Solaris limit according to your draft book).I am attaching a diff containing my modifications.Bob======================================Bob Friesenhahnbfriesen@simple.dallas.tx.ushttp://www.cyberramp.net/~bfriesen--- bw_lat.sh.old	Wed Apr 22 21:40:56 1998+++ bw_lat.sh	Wed Apr 22 21:31:37 1998@@ -1,13 +1,14 @@-# !/usr/dt/bin/dtksh-# !/bin/ksh-# set -x+#!/usr/dt/bin/dtksh+#!/bin/ksh+#set -x  # Requires a ksh newer than 11/16/88 because it uses floating point # arithmetic and printf.  /usr/dt/bin/dtksh on Solaris and Digital Unix # is such a beast, as are some vendor's ksh93 binary. # /usr/dt/bin/dtksh on Digital Unix 4.0B appears brain dead. -float sum=0.0 usec=0.0+float sum=0.0+float usec=0.0  function doit {@@ -69,7 +70,7 @@  if [ -x bw_svmsg ] then-	for xfersize in 1024 2048 4096 8192 16384+	for xfersize in 1024 2048 #4096 8192 16384 	do 		for i in 1 2 3 4 5 		do@@ -116,7 +117,7 @@ then 	for i in 1 2 3 4 5 	do-		doit "lat_door 10000"+		doit "lat_door /tmp/bench 10000" 	done 	echo "*****" 	average_lat 5
