grep sdosanjh filename |read var1 var2 var3
echo $var1 $var2 $var3

There is a problem with this construct. Theoretically this should work all the time, but it does not. When I use Solaris sh, in some releases this works and in some it does not. This is why I did not recommend it. I guess QC at Sun is not what it used to be. I wonder which other OS this is not working. This is also warning for people moving scripts around. At the same time in ksh it works fine in the same OS. Around Solaris 6 or 7 this forced me to rewrite half of my scripts.
