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备份Powershell(v2)脚本中的某些文件。
I'm trying to use 7-Zip to backup some files inside a Powershell (v2) script.
我有:
$zipPath = "C:\Program Files\7-Zip\7z.exe"
[Array]$zipArgs = "-mx=9 a", "`"c:\BackupFolder\backup.zip`"", "`"c:\BackupFrom\backMeUp.txt`""
&$zipPath $zipArgs;
但是当我运行它时,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
将此写到屏幕上我会得到:
Writing this to the screen I get:
C:\Program Files\7-Zip\7z.exe -mx=9 a "c:\BackupFolder\backup.zip" "c:\BackupFrom\backMeUp.txt"
所以我认为我需要在路径两边加上引号到7z.exe,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 Files\7-Zip\7z.exe"
$zipPath = " `"$zipPath`" "
[Array]$zipArgs = "-mx=9 a", "`"c:\BackupFolder\backup.zip`"", "`"c:\BackupFrom\backMeUp.txt`""
&$zipPath $zipArgs;
但是随后出现以下错误:
But then I get the following error:
The term '"C:\Program Files\7-Zip\7z.exe"' is not recognized as the name of a cmdlet, function, script file
, or operable program. Check the spelling of the name, or if a path was included, verify that the path is c
orrect and try again.
At C:\BackupScript\Backup.ps1:45 char:22
+ & <<<< `"$zipPath`" $zipArgs;
+ CategoryInfo : ObjectNotFound: ("C:\Program Files\7-Zip\7z.exe":String) [], CommandNotFound
Exception
+ FullyQualifiedErrorId : CommandNotFoundException
写出来可以给我:
"C:\Program Files\7-Zip\7z.exe" -mx=9 a "c:\BackupFolder\backup.zip" "c:\BackupFrom\backMeUp.txt"
直接粘贴到命令窗口中时,其工作原理与预期的一样。
我已经尝试了一段时间,但是假设我错过了一些东西(可能很明显)。有人可以看到我需要做些什么才能使它运行吗?
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
找到了此脚本并根据您的需要进行了调整。您能尝试吗?
Found this script and adapted it to your needs. Can you please try:
$7zipPath = "$env:ProgramFiles\7-Zip\7z.exe"
if (-not (Test-Path -Path $7zipPath -PathType Leaf)) {
throw "7 zip file '$7zipPath' not found"
}
Set-Alias 7zip $7zipPath
$Source = "c:\BackupFrom\backMeUp.txt"
$Target = "c:\BackupFolder\backup.zip"
7zip a -mx=9 $Target $Source
