压缩存档并保留相对路径

Question

我很难让compress-archive做我想做的事...

我有一个根项目文件夹，我想压缩子目录中的某些文件并保留相对路径。例如： / ├── _scripts ├── ├─_module1 | | └── filex.js | └─_module2 | ├── file1.js | └── file2.txt

因此，我想从我的根目录创建一个包含module2/*的zip文件，并且我想保留文件夹结构。我希望我的拉链包含： scripts/module2/file1.js scripts/module2/file2.txt

但是当我从根文件夹运行此命令时： Compress-Archive -Path "scripts\module2\*" -DestinationPath tmp.zip

zip文件的内容仅包含： /file1.js /file2.txt

Answer 1

看来Compress-Archive（从Windows PowerShell v5.1开始）不支持您想要的内容：

以文件夹为目标，将该文件夹的子树递归地添加到存档中，但仅按目标文件夹的名称（它将成为存档中的子文件夹）添加，而不是其< em>路径。

具体地说，

Compress-Archive -Path scripts\module2 -DestinationPath tmp.zip

（递归）将scripts\module2的内容存储在tmp.zip中，但不使用存档内部路径.\scripts\module2，而仅使用.\module2-目标文件夹的名称（最后一个输入路径组件）。

含义是，您必须传递文件夹scripts才能获得所需的存档内部路径，但这总是包含scripts的 entire子树 ，因为Compress-Archive没有提供包含/排除机制。

一个麻烦的选项是在$env:TEMP文件夹中重新创建所需的层次结构，在其中复制目标文件夹，对重新创建的层次结构的根目录运行Compress-Archive，然后进行清理：

New-Item -Force -ItemType Directory $env:TEMP/scripts
Copy-Item -Recurse -Force scripts/module2 $env:TEMP/scripts
Compress-Archive -LiteralPath $env:TEMP/scripts -DestinationPath tmp.zip
Remove-Item $env:TEMP/Scripts -Recurse -Whatif

---

否则，您也许能够找到解决方案：

• ，直接使用.NET v4.5 + [System.IO.Compression.ZipFile] class；您可以使用Add-Type -Assembly System.IO.Compression.FileSystem将其加载到会话中（在PowerShell Core 中不是必需的）。

• 通过使用诸如7-Zip，

之类的外部程序

cumbersome technique mklement0 mentioned为我工作。下面是我创建的脚本，用于支持与文件夹混合的各种文件的列表。

# Compress LFS based files into a zip
# To use
#  1. place this script in the root folder
#  2. modify the contents of $lfsAssetFiles to point to files relative to this root folder
#  3. modify $zipDestination to be where you want the resultant zip to be placed
# based off of https://stackoverflow.com/a/51394271

# this should match files being .gitignored
$lfsAssetFiles = 
"\Assets\Project\Plugins\x32",
"\Assets\Project\Plugins\x64\HugePlugin.dll"

# This is where the contents of the zip file will be structured, because placing them inside of a specific folder of the zip is difficult otherwise
$zipStruct = $PSScriptRoot + "\zipStruct"

# the actual zip file that will be created
$zipDestination = "C:\Dropbox\GitLfsZip\ProjectNameLfs.zip"

# remove files from previous runs of this script
If(Test-path $zipStruct) {Remove-item $zipStruct -Recurse}
If(Test-path $zipDestination) {Remove-item $zipDestination}

Foreach ($entry in $lfsAssetFiles)
{
  # form absolute path to source each file to be included in the zip
  $sourcePath = $PSScriptRoot + $entry;

  # get the parent directories of the path. If the entry itself is a directory, we still only need the parent as the directory will be created when it is copied over.
  $entryPath = Split-Path -Parent $entry

  # form what the path will look like in the destination
  $entryPath = $zipStruct + $entryPath

  # ensure the folders to the entry path exist
  $createdPath = New-Item -Force -ItemType Directory $entryPath

  # copy the file or directory
  Copy-Item -Recurse -Force $sourcePath $createdPath
}

# create a zip file https://blogs.technet.microsoft.com/heyscriptingguy/2015/page/59/
Add-Type -AssemblyName "system.io.compression.filesystem"
[io.compression.zipfile]::CreateFromDirectory($zipStruct, $zipDestination)
# Compress-Archive doesn't work here because it includes the "zipStruct" folder: Compress-Archive -Path $zipStruct -DestinationPath $zipDestination

我想这样做，而不必将整个结构复制到临时目录中。

#build list of files to compress
$files = @(Get-ChildItem -Path .\procedimentos -Recurse | Where-Object -Property Name -EQ procedimentos.xlsx);
$files += @(Get-ChildItem -Path .\procedimentos -Recurse | Where-Object -Property Name -CLike procedimento_*_fs_*_d_*.xml);
$files += @(Get-ChildItem -Path .\procedimentos -Recurse | Where-Object -Property FullName -CLike *\documentos_*_fs_*_d_*);

# exclude directory entries and generate fullpath list
$filesFullPath = $files | Where-Object -Property Attributes -CContains Archive | ForEach-Object -Process {Write-Output -InputObject $_.FullName}

#create zip file
$zipFileName = 'procedimentos.zip'
$zip = [System.IO.Compression.ZipFile]::Open((Join-Path -Path $(Resolve-Path -Path ".") -ChildPath $zipFileName), [System.IO.Compression.ZipArchiveMode]::Create)

#write entries with relative paths as names
foreach ($fname in $filesFullPath) {
    $rname = $(Resolve-Path -Path $fname -Relative) -replace '\.\\',''
    echo $rname
    $zentry = $zip.CreateEntry($rname)
    $zentryWriter = New-Object -TypeName System.IO.BinaryWriter $zentry.Open()
    $zentryWriter.Write([System.IO.File]::ReadAllBytes($fname))
    $zentryWriter.Flush()
    $zentryWriter.Close()
}

# clean up
Get-Variable -exclude Runspace | Where-Object {$_.Value -is [System.IDisposable]} | Foreach-Object {$_.Value.Dispose(); Remove-Variable $_.Name};

这是一个有点旧的线程，但是我认为这将帮助人们通过PowerShell 5.1创建zip文件，PowerShell 5.1是当今Windows 10安装的标准配置。脚本允许您保留原始的子目录结构，并排除一些不必要的子树/文件。这是我用来存档Visual Studio解决方案源代码的方法：

Write-Output "Zipping Visual Studio solution..."

# top level from where to start and location of the zip file
$path = "C:\TheSolution"
# top path that we want to keep in the source code zip file
$subdir = "source\TheSolution"
# location of the zip file
$ZipFile = "${path}\TheSolution.zip"

# change current directory
Set-Location "$path"

# collecting list of files that we want to archive excluding those that we don't want to preserve
$Files  = @(Get-ChildItem "${subdir}" -Recurse -File | Where-Object {$_.PSParentPath -inotmatch "x64|packages|.vs|Win32"})
$Files += @(Get-ChildItem "${subdir}\packages" -Recurse -File)
$Files += @(Get-ChildItem "${subdir}\.git" -Recurse -File)
$FullFilenames = $files | ForEach-Object -Process {Write-Output -InputObject $_.FullName}

# remove old zip file
if (Test-Path $ZipFile) { Remove-Item $ZipFile -ErrorAction Stop }

#create zip file
Add-Type -AssemblyName System.IO.Compression
Add-Type -AssemblyName System.IO.Compression.FileSystem
$zip = [System.IO.Compression.ZipFile]::Open(($ZipFile), [System.IO.Compression.ZipArchiveMode]::Create)

# write entries with relative paths as names
foreach ($fname in $FullFilenames) {
    $rname = $(Resolve-Path -Path $fname -Relative) -replace '\.\\',''
    Write-Output $rname
    $zentry = $zip.CreateEntry($rname)
    $zentryWriter = New-Object -TypeName System.IO.BinaryWriter $zentry.Open()
    $zentryWriter.Write([System.IO.File]::ReadAllBytes($fname))
    $zentryWriter.Flush()
    $zentryWriter.Close()
}

# release zip file
$zip.Dispose()
