Subject: Re: For Loop

I would add that you can use backticks to execute a shell command, as follows:
`scp "#{group}" user@server1:/tmp`

I would suggest reading some Ruby tutorials online, because it's
pretty different from Bash, and you often won't want to just translate
things literally. Learning one's second programming language is a big
deal :-)
