Enclose lines in markers using regex in Gvim

I have following simple text:

one
a line
more lines
more text
end

I want to enclose each line in >> and << using regex. Following work individually: 

:%s/^/>>/g
:%s/$/<</g

However, how can I do it with one command. I tried following but they do not work: 

:%s/^([.]+)$/>>\1<</g
:%s/\v^([.]+)$/>>\1<</g
:%s/([.]+)/>>\1<</g

Thanks for your help.

:%s/.*/>>&<</

& mean matched whole part. And not require g flag.

Try using the following:

:%s/^\(.*\)$/>>\1<</g

I notice a problem with your current attempts, for example this one:

:%s/^([.]+)$/>>\1<</g

You are matching a literal dot when you use [.], which is a character class. Doubtless, most of the time this pattern won't match any line, unless it consists entirely of dots.

Also, parentheses need to be escaped in Vim regexes.
