Unified interface for ssh or local commands.

For running local commands it is very much like using the Open3 standard lib, only it returns the same response object as ssh commands.

require 'here_or_there'
include HereOrThere

command = 'whoami'
resp = run_local( command )
resp.stdout
# => "user\n"
resp.stderr
# => ""
resp.success?
# => true

Remote processes are very similar, except that you also pass the information required to establish the remote connection.

require 'here_or_there'
include HereOrThere

command = 'whoami'
resp = run_remote( command, hostname: 'your_remote', username: 'user', password: 'password' )
resp.stdout
# => "user\n"
resp.stderr
# => ""
resp.success?
# => true

# if you have .ssh/config setup, hostname is all that is required

resp = run_remote( command, hostname: 'your_remote' )
resp.stdout
# => "ssh_user\n"
resp.stderr
# => ""
resp.success?
# => true

Response objects respond as you expect they would to stdout and stderr giving you those values. It also has a success? method that will retun a bolean of whether the command exited 0 or not.

Here or There is tested against and supports:

• 2.0.0
• 1.9.3
• rubinius 2.0

If you have experience with and could help out adding jruby support that would be greatly appreciated.

Tests are run using rspec. Net::SSH sessions are stubbed to prevent needing an actual connection for the suite to run.

$ rspec
