I have a snippet of code, simply trying to execute a script on a remote server, in the event that it fails, I'd like to make a follow-up call, imagine this:
require 'rubygems'
require 'net/ssh'
require 'etc'
server = 'localhost'
Net::SSH.start(server, Etc.getlogin) do |ssh|
puts (ssh.exec("true") ? 'Exit Success' : "Exit Failure")
puts (ssh.exec("false") ? 'Exit Success' : "Exit Failure")
end
I would expect (ignoring that stdout and stderr are printed in my contrived example) - but first line should exit with 0
which I would expect Ruby would interperate as false
and display "Exit Failure" (sure, so the logic is wrong, the ternary needs to be flipped) - but the second line should exit with the opposite status, and it doesn't.
I can't even find anything in the documentation about how to do this, and I'm a little worried that I might be doing it wrong?!
