why does ssh break a /bin/sh while loop?

[roswell1329]

I'm having trouble using ssh to execute a remote command inside a /bin/sh script. It executes just fine once, but it stops the loop execution there:

cat /home/guest/systems | \
while read line
do 
ssh -l root $line "ls -alF /etc"
done

Other commands between the do and done work and won't kill the loop, but for some reason as soon as I add the ssh the loop dies. The ssh command isn't failing, so I don't think it's the return code for ssh that's killing the loop, but I don't know why it's dying. Anyone have any ideas on why this is happening and how to avoid it?

bash, csh, ksh?

bash# for line in `cat /home/guest/systems`; do ssh -l root $line "ls -alF /etc" ; done

Seems to work fine


Edit: ah.. the 'normal' bourne shell brb

Hmm.. logic error? Pipe being connected to ssh instead of while?

The bash line above should work in sh too..

Thanks, SirDice. That worked. I'm thinking it was the pipe in combination with the ssh in my loop that killed it.
