I've created a program that will search our work server where Ghostscripts occur. How it accomplishes this is by first sshing to the server specified, running a bash command to search the server for Ghostscripts caused by our guy that uses them, most frequently. If it finds one, it e-mails somebody on my team. It will also e-mail if it doesn't find one.I'm curious to know if there are other ways I can do this specific task. Better syntax, etc..#!/local/usr/bin/rubyrequire 'rubygems'require '<mailgem>'require 'etc'require 'net/ssh'class GhostScript  attr_accessor :host, :usr, :pass  def initialize(host, usr, pass)    @host = host    @usr  = usr    @pass = pass  end  def script_search    ssh = Net::SSH.start(host, usr, :password => pass)    res = ssh.exec!('ps -u <user>|grep gs')    if res == nil      MailGem::Mail.new do |m|        m.to      = '<email-address>'        m.subject = 'GhostScript not found'        m.body    = GS not found on server: #{host}      end.send      else      alert(res)    end  end  def alert(res)    MailGem::Mail.new do |m|      m.to      = '<email-address>'      m.subject = 'GhostScript found'      m.body    = GS script found on server: #{host},                  Results of search: #{res}    end.send  endendcheck = GhostScript.new('<server>', Etc.getlogin, nil)check.script_search
Ghostscript check, sends e-mail if one occurs
ruby;email;ssh;status monitoring
Looks pretty good, just some minor details:if res == nil -> if !resDRY the sending of the email by creating a new method: send_email(to, subject, body)Subjective: I'd not include a blank lines when there is a change of indentation level (between class and attr_accesor)
