Passing variables to remote hosts through ssh
I have a central administration server that has root-level public key
access to my other hosts. I run scripts that use ssh to execute commands
on all my hosts. How do I pass variables through ssh?
For example, suppose I want to create a directory called /tmp/newdir on
for i in `cat /long/list/of/hosts`
ssh $i '/usr/bin/mkdir /tmp/$DIRNAME'
This doesn't work, because $DIRNAME doesn't get passed to the remote host.
How can I make it work without hardcoding newdir in the ssh line?
