使用 PowerShell 时，空格会导致路径分裂

当在包含空格的路径上调用 exe 时，我遇到了 Powershell 的问题。

PS C:\Windows Services> invoke-expression "C:\Windows Services\MyService.exe"

术语“ C: Windows”不能识别为 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，请验证路径是否正确，然后再试一次。

它似乎在“ Windows”和“服务”之间的空间上分裂。有什么办法可以解决这个问题吗？

Would this do what you want?:

& "C:\Windows Services\MyService.exe"

Use &, the call operator, to invoke commands whose names or paths are stored in quoted strings and/or are referenced via variables, as in the accepted answer. Invoke-Expression is not only the wrong tool to use in this particular case, it should generally be avoided.

You can escape the space by using single quotations and a backtick before the space:

$path = 'C:\Windows Services\MyService.exe'
$path -replace ' ', '` '
invoke-expression $path

There's a hack I've used since the Invoke-Expression works fine for me.

You could set the current location to the path with spaces, invoke the expression, get back to your previous location and continue:

$currLocation = Get-Location
Set-Location = "C:\Windows Services\"
Invoke-Expression ".\MyService.exe"
Set-Location $currLocation

This will only work if the exe doesn't have any spaces in its name.

Hope this helps

Not sure if someone still needs it... I needed to invoke msbuild in powershell and following worked fine:

$MSBuild = "${Env:ProgramFiles(x86)}\Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin\MSBuild.exe"


& $MSBuild $PathToSolution /p:OutDir=$OutDirVar /t:Rebuild /p:Configuration=Release

Using Powershell on Windows10 in 2018, what worked for me was simply to replace double quotes ABC0 by simple quotes '. Adding the backtick before the space, as suggested in an answer, broke the path.

For any file path with space, simply put them in double quotations will work in Windows Powershell. For example, if you want to go to Program Files directory, instead of use

PS C:\> cd Program Files

which will induce error, simply use the following will solve the problem:

PS C:\> cd "Program Files"

Please use this simple one liner:

Invoke-Expression "C:\'Program Files (x86)\Microsoft Office\root\Office16'\EXCEL.EXE"

Try this, simple and without much change:

invoke-expression "'C:\Windows Services\MyService.exe'"

using single quotations at the beginning and end of the path.

This worked for me:

$scanresults = Invoke-Expression "& 'C:\Program Files (x86)\Nmap\nmap.exe' -vv -sn 192.168.1.1-150 --open"

Can use the . dot operator.

. "C:\Users\user\AppData\Local\Programs\Microsoft VS Code\bin\code.cmd"

or the Start-Process command

Start-Process -PSPath "C:\Users\user\AppData\Local\Programs\Microsoft VS Code\bin\code.cmd"

or using ProcessStartInfo and Process

$ProcessInfo = New-Object -TypeName System.Diagnostics.ProcessStartInfo
$ProcessInfo.FileName = 'C:\WINDOWS\System32\WindowsPowerShell\v1.0\powershell.exe'
if($Admin){ $ProcessInfo.Verb = 'runas' }
$ProcessInfo.UseShellExecute = $false


$CommandParameters = '-noexit -noprofile -command Set-Location -LiteralPath c:\; $host.ui.RawUI.WindowTitle = ''[{0}] PS''; Set-PSReadlineOption -HistorySaveStyle SaveNothing;' -f $Cred.UserName
$ProcessInfo.Arguments = $CommandParameters
$ProcessInfo.Domain = ($Cred.UserName -split '\\')[0]
$ProcessInfo.UserName = ($Cred.UserName -split '\\')[1]
$ProcessInfo.Password = $Cred.Password


$ProcessObject = New-Object -TypeName System.Diagnostics.Process
$ProcessObject.StartInfo = $ProcessInfo
$ProcessObject.Start() | Out-Null

Just put ${yourpathtofile/folder}

PowerShell does not count spaces; to tell PowerShell to consider the whole path including spaces, add your path in between ${ & }.

Simply put the path in double quotes in front of cd, Like this:

cd "C:\Users\MyComputer\Documents\Visual Studio 2019\Projects"

What worked for me (I needed the path to create a MySQL dump), was to place the directory in between 6 double quotes like so:

$path = """C:\Path\To\File"""

Due to several PowerShell quoting rules that are used for passing arguments to native commands which also have specific experimental Features in PowerShell, quoting might get very confusing. Therefore the solution in some cases might be simply to don't go down the rabbit hole:

Avoid quoting file paths with spaces by using the 8.3 filenames

$FSO = New-Object -ComObject Scripting.FileSystemObject
$FSO.getfile('C:\Windows Services\MyService.exe').ShortPath
C:\WINDOW~1\MYSERV~1.EXE
