[luau] cracked shell?

[Thomas David Burns]

I'm using csh. I had several working shell scripts basically structured
like this:

#/bin/csh
 
while read line 
do
   echo $line 
done


Now none of them work. When I execute the above in a file named 'test',
I get the following error message:

echo x|/test
while - Expression syntax


What could make my csh start acting different, other than my system has
been compromised and they've replaced my csh with something broken?
Ideas?

P.S. Disclosure - I'm actually running these scripts on IRIX, so
technically this post is off-topic. I hope you don't feel too exploited.
