Net::SSH::Shell is a library for interacting with stateful (e.g., interactive) shells on remote hosts. It hides (or tries to hide) the potentially complex Net::SSH state machines you'd otherwise need to write to interact with “su” and similar shells.
One of the significant benefits you get from this library versus using Net::SSH directly is that your shell is stateful. With Net::SSH, if you invoke “cd /” in one exec call, and “pwd” in another, the two are done in different shells so the directory change in the first has no effect on the working directory of the second. With Net::SSH::Shell, though, commands are all invoked via the same shell, so changes in directory or additions to the environment all affect subsequent commands.
Interact with login shells
Support for “subshell” environments, like “su” or “sudo bash”
In a nutshell:
require 'net/ssh/shell' Net::SSH::Start('host', 'user') do |ssh| ssh.shell do |sh| sh.execute "cd /usr/local" sh.execute "pwd" sh.execute "export FOO=bar" sh.execute "echo $FOO" end end
See Net::SSH::Shell for more documentation.
net-ssh (version 2)
If you want to use any of the Rake tasks, you'll need:
Echoe (for the Rakefile)
gem install net-ssh-shell (might need sudo privileges)
