Hi,

I'm running a command like this:

for i in server1 server2;do ssh root@$i "`hostname`";done.

However the hostname command always outputs the hostname of the server
that the above command is run from. I'd like to know how to run this
hostname command so that it actually runs on server 1, server2 etc..

Thanks
Dan


Use the following
for i in server1 server2;do ssh root@$i '`hostname`';done.


Explanation: `hostname`, or $(hostname), is already evaluated on the source host by your shell (even inside of "...") , not on the target host.
