for-loop in shell between hosts (with ssh) -

-

i have loop go through other amazon instances:

#!/bin/bash list="ec2xxxa.compute.amazonaws.com ec2xxxb-central-1.compute.amazonaws.com" sshkey="ssh -tt -i key.pem centos@"    in $list;     ${sshkey}$i hostname

now try loop through list , print hostname of 2 instances of amazon. works first one. after loop doesn't go further:.

./script.sh ip-172-xx-xx-01 connection ec2-xxxa-1.compute.amazonaws.com closed. last login: thu jan 28 14:09:48 2016 ip-172-xx-xx-01.compute.internal [centos@ip-172-xx-xx-01 ~]$

so can see it's telling me closed connection after closing connection prompt shows ip of host again. have type exit , after it, goes further following host (which have exit).

adding exit in script did not help. it's stopping after first host.

try removing -tt option command.
