下面是sonjz回答的一个稍微改进的版本，它增加了一个覆盖选项。

function Zip-Files(
        [Parameter(Position=0, Mandatory=$true, ValueFromPipeline=$false)]
        [string] $zipfilename,
        [Parameter(Position=1, Mandatory=$true, ValueFromPipeline=$false)]
        [string] $sourcedir,
        [Parameter(Position=2, Mandatory=$false, ValueFromPipeline=$false)]
        [bool] $overwrite)

{
   Add-Type -Assembly System.IO.Compression.FileSystem
   $compressionLevel = [System.IO.Compression.CompressionLevel]::Optimal

    if ($overwrite -eq $true )
    {
        if (Test-Path $zipfilename)
        {
            Remove-Item $zipfilename
        }
    }

    [System.IO.Compression.ZipFile]::CreateFromDirectory($sourcedir, $zipfilename, $compressionLevel, $false)
}

这里有一个完整的命令行示例，可以从cmd.exe或ssh或您想要的任何地方启动!

powershell.exe -nologo -noprofile -command "&{ Add-Type -A 'System.IO.Compression.FileSystem' [System.IO.Compression.ZipFile]::CreateFromDirectory('c:/path/to/source/folder/', 'c:/path/to/output/file.zip');}"

问候

安装7zip(或下载命令行版本)并使用PowerShell方法:

function create-7zip([String] $aDirectory, [String] $aZipfile){
    [string]$pathToZipExe = "$($Env:ProgramFiles)\7-Zip\7z.exe";
    [Array]$arguments = "a", "-tzip", "$aZipfile", "$aDirectory", "-r";
    & $pathToZipExe $arguments;
}

你可以这样调用它:

create-7zip "c:\temp\myFolder" "c:\temp\myFolder.zip"

System.IO.Packaging.ZipPackage呢?

它需要。net 3.0或更高版本。

#Load some assemblys. (No line break!)
[System.Reflection.Assembly]::Load("WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35")

#Create a zip file named "MyZipFile.zip". (No line break!)
$ZipPackage=[System.IO.Packaging.ZipPackage]::Open("C:\MyZipFile.zip",
   [System.IO.FileMode]"OpenOrCreate", [System.IO.FileAccess]"ReadWrite")

#The files I want to add to my archive:
$files = @("/Penguins.jpg", "/Lighthouse.jpg")

#For each file you want to add, we must extract the bytes
#and add them to a part of the zip file.
ForEach ($file In $files)
{
   $partName=New-Object System.Uri($file, [System.UriKind]"Relative")
   #Create each part. (No line break!)
   $part=$ZipPackage.CreatePart($partName, "",
      [System.IO.Packaging.CompressionOption]"Maximum")
   $bytes=[System.IO.File]::ReadAllBytes($file)
   $stream=$part.GetStream()
   $stream.Write($bytes, 0, $bytes.Length)
   $stream.Close()
}

#Close the package when we're done.
$ZipPackage.Close()

通过安德斯·赫塞尔博姆

PowerShell v5.0增加了压缩-归档和扩展-归档cmdlet。链接页面有完整的例子，但它的要点是:

# Create a zip file with the contents of C:\Stuff\
Compress-Archive -Path C:\Stuff -DestinationPath archive.zip

# Add more files to the zip file
# (Existing files in the zip file with the same name are replaced)
Compress-Archive -Path C:\OtherStuff\*.txt -Update -DestinationPath archive.zip

# Extract the zip file to C:\Destination\
Expand-Archive -Path archive.zip -DestinationPath C:\Destination

function Zip-File
    {
    param (
    [string]$ZipName,
    [string]$SourceDirectory 

    )
       Add-Type -Assembly System.IO.Compression.FileSystem
       $Compress = [System.IO.Compression.CompressionLevel]::Optimal
       [System.IO.Compression.ZipFile]::CreateFromDirectory($SourceDirectory,
            $ZipName, $Compress, $false)
    }

注意: ZipName:要创建的Zip文件的完整路径。

SourceDirectory:包含要压缩的文件的目录的完整路径。
