I have the following in a script

for server in ${servers[@]}; do
 echo ${server}
 ssh user@${server} "for i in /tmp/foo* ; do echo ${i}; done"

But it doesn't work. Weird thing, I see $I amount of return lines. So if I have ten files, I see ten blank lines.

look also at GNU Parallel's --sshlogin option. – Sebastian Jun 10 '11 at 8:48

Your local shell interpretes the ${i} within double quotes ("), so the command works out to

ssh "for i in /tmp/foo* ; do echo; done"

Simply use single quotes (') instead and your problem will disappear:

ssh user@${server} 'for i in /tmp/foo* ; do echo $i; done'

Just to clarify your answer: ssh 'for i in /tmp/foo* ; do echo $i; done' Thanks! – Eldelshell Sep 1 '10 at 11:48
