如何从命令行运行Powershell脚本并将目录作为参数传递

My Powershell script, Foo.ps1:

我的Powershell脚本，Foo.ps1：

Function Foo($directory)
{
    echo $directory
}

if ($args.Length -eq 0)
{
    echo "Usage: Foo <directory>"
}
else
{
    Foo($args[0])
}

From the Windows console:

从Windows控制台：

powershell -command .\Foo.ps1

Results in: "The term '.\Foo.ps1' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again."

结果：“术语'。\ Foo.ps1'未被识别为cmdlet，函数，脚本文件或可操作程序的名称。检查名称的拼写，或者如果包含路径，请验证路径是正确的，然后再试一次。“

This is despite Foo.ps1 being in the current directory from where I am calling Powershell. I then tried to call it specifying the full path to the script file; because this path contains a space I believe I have to quote it in some way. Also I need to pass an argument to the script which is also a file name that contains one or more spaces. No matter what I try I can't get it to work. This is my best guess so far:

尽管Foo.ps1位于我调用Powershell的当前目录中。然后我试着调用它来指定脚本文件的完整路径;因为这条路径包含一个空间我相信我必须以某种方式引用它。此外，我需要将参数传递给脚本，该脚本也是包含一个或多个空格的文件名。无论我尝试什么，我都无法让它发挥作用。到目前为止，这是我最好的猜测：

powershell -command "'C:\Dummy Directory 1\Foo.ps1' 'C:\Dummy Directory 2\File.txt'"

Which gives the error "Unexpected token 'C:\Dummy Directory 2\File.txt' in expression or statement. At line:1 char:136".

这在表达式或语句中给出了错误“Unexpected token'C：\ Dummy Directory 2 \ File.txt'。在第1行：char：136”。

Edit: I have worked out why

编辑：我找出了原因

powershell -command .\Foo.ps1

did not work. This was because my Microsoft.PowerShell_profile.ps1 file had

不工作。这是因为我的Microsoft.PowerShell_profile.ps1文件有

cd C:\

cd C：\

so as soon as powershell was starting up it was changing directory.

所以，一旦powershell启动它就会改变目录。

5 个解决方案

#1

try this:

尝试这个：

powershell "C:\Dummy Directory 1\Foo.ps1 'C:\Dummy Directory 2\File.txt'"

#2

you are calling a script file not a command so you have to use -file eg :

您正在调用脚本文件而不是命令，因此您必须使用-file，例如：

powershell -executionPolicy bypass -noexit -file "c:\temp\test.ps1" "c:\test with space"

for PS V2

对于PS V2

powershell.exe -noexit &'c:\my scripts\test.ps1'

#3

Using the flag -Command you can execute your entire powershell line as if it was a command in the PowerShell prompt:

使用标志-Command，您可以执行整个PowerShell行，就好像它是PowerShell提示符中的命令一样：

powershell -Command "& '<PATH_TO_PS1_FILE>' '<ARG_1>' '<ARG_2>' ... '<ARG_N>'"

This solved my issue with running PowerShell commands in Visual Studio Post-Build and Pre-Build events.

这解决了我在Visual Studio Post-Build和Pre-Build事件中运行PowerShell命令的问题。

#4

Change your code to the following :

将您的代码更改为以下内容：

Function Foo($directory)
    {
        echo $directory
    }

    if ($args.Length -eq 0)
    {
        echo "Usage: Foo <directory>"
    }
    else
    {
        Foo([string[]]$args)
    }

And then invoke it as:

然后将其调用为：

powershell -ExecutionPolicy RemoteSigned -File "c:\foo.ps1" "c:\Documents and Settings" "c:\test"

powershell -ExecutionPolicy RemoteSigned -File“c：\ foo.ps1”“c：\ Documents and Settings”“c：\ test”

#5

Add the param declation at the top of ps1 file

在ps1文件的顶部添加param declation

test.ps1

test.ps1

param(
  # Our preferred encoding
  [parameter(Mandatory=$false)]
  [ValidateSet("UTF8","Unicode","UTF7","ASCII","UTF32","BigEndianUnicode")]
  [string]$Encoding = "UTF8"
)

write ("Encoding : {0}" -f $Encoding)

result

结果

C:\temp> .\test.ps1 -Encoding ASCII
Encoding : ASCII
