ruby 使用变量执行 bash 命令

Question

我需要在 Ruby 脚本中执行 Bash 命令。根据 "6 Ways to Run Shell Commands in Ruby" by Nate Murray，大约有 6 种方法可以做到这一点以及其他一些谷歌搜索的来源。

print "enter myid: "
myID = gets
myID = myID.downcase
myID = myID.chomp 
print "enter host: "
host = gets
host = host.downcase
host = host.chomp 
print "winexe to host: ",host,"\n"
command = "winexe -U domain\\\\",ID," //",host," \"cmd\""
exec command 

Answer 1

实际上你可以链接这些方法，puts 会为你打印一个换行符，所以这可能只是:

print "enter myid: "
myID = STDIN.gets.downcase.chomp

print "enter host: "
host = STDIN.gets.downcase.chomp

puts "winexe to host: #{host}"
command = "winexe -U dmn1\\\\#{myID} //#{host} \"cmd\""
exec command
