在Ruby中使用变量执行cmd命令失败

Question

I'm writting Windows account report in Ruby. I have an array with usernames

users_local = [user1, user2, user3]

For every single user I want to execute a cmd command to get more information about every user

system "net user '#{users_local[0]}'"

and now I get

The user name could not be found.

More help is available by typing NET HELPMSG 2221.

When I execute directly system 'user net user1' the command is executing correctly. Any ideas why executing command with variable fails?

Answer 1

摆脱单引号应该做到这一点：

system "net user #{users_local[0]}"
