Plink和PowerShell的参数问题

Question

我正在尝试使用plink切换到交换机，但是我的参数始终出现错误。

$plink = 'C:\Program Files (x86)\PuTTY\plink.exe'
$switch = "172.20.19.50"
$commands = "c:\scripts\cmd.txt"
$username = Read-Host "User name"
$pw =  Read-Host -Prompt "Enter password" -AsSecureString
$plink -l $username -pw $pw -m $commands -ssh $switch 

这些是我得到的错误：

You must provide a value expression on the right-hand side of the '-' operator.
At line:7 char:8

Unexpected token 'l' in expression or statement.
At line:7 char:9

Unexpected token 'username' in expression or statement.
At line:7 char:11

Unexpected token '-pw' in expression or statement.
At line:7 char:21

Unexpected token 'pw' in expression or statement.
At line:7 char:25

Unexpected token '-m' in expression or statement.
At line:7 char:29

Unexpected token 'commands' in expression or statement.
At line:7 char:32

Unexpected token '-ssh' in expression or statement.
At line:7 char:42

Unexpected token 'switch' in expression or statement.
At line:7 char:47

据我所知，我的参数是正确的，知道为什么它不起作用吗？

您需要告诉powershell您正在运行带有参数的命令，否则它不知道如何解释参数列表，要使其正常工作，您只需在命令前添加&符号即可：

& $plink -l $username -pw $pw -m $commands -ssh $switch
