在 Powershell 脚本中运行 7-Zip [英] Running 7-Zip from within a Powershell script

问题描述

我正在尝试使用 7-Zip 来备份 Powershell (v2) 脚本中的一些文件.

I'm trying to use 7-Zip to backup some files inside a Powershell (v2) script.

我有:

$zipPath = "C:Program Files7-Zip7z.exe"
[Array]$zipArgs = "-mx=9 a", "`"c:BackupFolderackup.zip`"", "`"c:BackupFromackMeUp.txt`""

&$zipPath $zipArgs;

但是当我运行这个时，我得到:

But when I run this I get:

7-Zip [64] 9.20  Copyright (c) 1999-2010 Igor Pavlov  2010-11-18


Error:
Incorrect command line

把这个写到屏幕上我得到:

Writing this to the screen I get:

C:Program Files7-Zip7z.exe -mx=9 a "c:BackupFolderackup.zip" "c:BackupFromackMeUp.txt"

所以我假设我需要在 7z.exe 的路径周围加上引号，这给了我:

So I assumed that I needed to put quotes around the path to 7z.exe, that gave me:

$zipPath = "C:Program Files7-Zip7z.exe"
$zipPath = " `"$zipPath`" "
[Array]$zipArgs = "-mx=9 a", "`"c:BackupFolderackup.zip`"", "`"c:BackupFromackMeUp.txt`""

&$zipPath $zipArgs;     

但是我收到以下错误:

    The term '"C:Program Files7-Zip7z.exe"' 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 c
orrect and try again.
At C:BackupScriptBackup.ps1:45 char:22
+                     & <<<< `"$zipPath`" $zipArgs;                    
    + CategoryInfo          : ObjectNotFound: ("C:Program Files7-Zip7z.exe":String) [], CommandNotFound 
   Exception
    + FullyQualifiedErrorId : CommandNotFoundException

写出来给我:

"C:Program Files7-Zip7z.exe" -mx=9 a "c:BackupFolderackup.zip" "c:BackupFromackMeUp.txt"

直接粘贴到命令窗口时，它按预期工作.我一直试图弄清楚这一点，但假设我遗漏了一些东西(可能很明显).任何人都可以看到我需要做什么才能运行此程序吗?

Which works as expected when pasting straight into a command window. I have been trying to figure this out for a while, but assume I am missing something (probably quite obvious). Can anybody see what I need to do to make this run?

推荐答案

Found this 脚本并根据您的需要进行调整.你能试试吗:

Found this script and adapted it to your needs. Can you please try:

$7zipPath = "$env:ProgramFiles7-Zip7z.exe"

if (-not (Test-Path -Path $7zipPath -PathType Leaf)) {
    throw "7 zip file '$7zipPath' not found"
}

Set-Alias 7zip $7zipPath

$Source = "c:BackupFromackMeUp.txt"
$Target = "c:BackupFolderackup.zip"

7zip a -mx=9 $Target $Source
