I'm new to Ruby, and just installed the 'net-ssh' gem to simply interact with SSH servers, a function which I need. The gem is properly located in its folder. I was not sure how to 'include' the gem in my RUBY script as instructed using the line: $:.push("/home/dangmoo/ruby/gems"), so I simply pasted it to the beginning. However, when I try to run a script using this gem, things don't work. This is how the script looks like: Although the script should simply return the output of the command 'ls' from my Linux SSH - it only output the HTML line 'This is a test' while the SSH part is totally ignored (without an error message). Do you see anything wrong here? Can you help me fix this? Thanks!
