Answer 1

你提到有「用引號問題」之前，您可以簡單地打印字符串的問題）。我假設你的意思是雙引號？修改Vapire的解決方案：

command = %Q{echo "double quoted string"} # store the command as string 
puts command        # print it before you execute it 
system(command)       # execute it in the shell 

Answer 2

你想發送給系統命令

command = "whoami" # store the command as string 
puts command  # print it before you execute it 
system(command)  # execute it in the shell
