How to access commands in bin folder through ruby net-ssh?

Question

I'm using net-ssh to connect to my server and need to run some ruby command.

The following doesn't work:

puts ssh.exec!("ruby -v")
bash: ruby: command not found

I always need to specify the full path:

puts ssh.exec!("/usr/local/rvm/rubies/ruby-1.9.3-p194/bin/ruby -v")

And it's like that for other command in general (rvm etc.)

Is there any option that would load the commands present in the bin folders?

I've tried that on my machine. But everything works fine. Is there something wrong with the server? Say, maybe have a try "ssh.exec 'echo $PATH'"? — halfelf, Aug 31 '12 at 07:53

you need to source .bashrc/.zshrc/ etc

ssh.exec!("source ~/.zshrc; /usr/bin/env ruby -v")
