Find latest available RVM version number

Question

I can't seem to find an easy way to identify the latest release of RVM from command line or rvm.beginrescueend.com!?!

I currently type rvm get latest every few days or so to update RVM. If version is same, RVM goes through the download & update process regardless. I'd like to be able to first 'see' if there's an update to get.

Anyone know how? I'm sure I'm missing the obvious...

you could use this one liner to check version:

$ curl -sS  https://api.github.com/repos/wayneeseguin/rvm/git/refs/tags | awk -F": |\"" '$2=="ref"{sub(/.*\//,"",$5); print $5}' | sort -V | tail -n 1
1.15.8

or a pure ruby one liner:

$ ruby -ropen-uri -rjson -e 'open("https://api.github.com/repos/wayneeseguin/rvm/git/refs/tags"){|r| puts JSON.parse(r.read).map{|l| l["ref"].gsub(/.*\//,"").split(".").map(&:to_i)}.sort.last.join(".") }'
1.15.8

but the simplest thing to do is:

$ curl https://raw.github.com/wayneeseguin/rvm/stable/VERSION
1.15.8
