Re: Strange shell script behaviour

Hi,
I've posted this up on the Sun forums but no joy, so what do you make
of this;

I'm having problems with rsh inside a shell script.
Look at the following script;

cat /etc/hosts | while read LINE
do
echo reading $LINE
done


This works fine - each line is echoed out to the screen.

Now if I add in a rsh;

cat /etc/hosts | while read LINE
do
echo reading $LINE
rsh `hostname` ls
done



It only processes the first line and then quits the loop, although the
rsh line works fine.
Can anyone explain why and/or give me a workaround?
I need to read a line at a time as I process each line through awk in
my real script.
Note that the rsh doesn't really do much, it just rsh's to itself and
executes an ls (which outputs to the screen no probs).
Also, /etc/hosts is just there as an example. Any file has the same
result.

ta..

If you must use rsh, "rsh -n" to keep remote process from consuming
the remaining input from stdin.
