ZIP

Question

Windows XP / Vista / 2003/2008中内置的ZIP压缩是否能够编写脚本？我必须从BAT / CMD文件中调用哪些可执行文件？或者是否可以使用VBScript进行？

我意识到使用WinZip，7-Zip和其他外部应用程序可以实现这一点，但我正在寻找不需要安装外部应用程序的东西。

Answer 1

还有zip和unzip使用压缩内置窗口的VBA方法，这可以让我们了解系统的运行方式。您可以将这些方法构建为您选择的脚本语言。

基本原则是在Windows中，您可以将zip文件视为目录，并将其复制到其中。因此，要创建一个新的zip文件，只需创建一个扩展名为.zip的文件，该文件具有空zip文件的正确标题。然后你关闭它，并告诉Windows你要将文件复制到它中，好像它是另一个目录。

解压缩更容易 - 只需将其视为目录。

    If Len(Dir(sPath)) > 0 Then Kill sPath
    Open sPath For Output As #1
    Print #1, Chr$(80) & Chr$(75) & Chr$(5) & Chr$(6) & String(18, 0)
    Close #1
End Sub

End Function

    Split97 = Evaluate("{""" & _
                       Application.Substitute(sStr, sdelim, """,""") & """}")
End Function

UNZIP

Sub Unzip1()
    Dim FSO As Object
    Dim oApp As Object
    Dim Fname As Variant
    Dim FileNameFolder As Variant
    Dim DefPath As String
    Dim strDate As String

    Fname = Application.GetOpenFilename(filefilter:="Zip Files (*.zip), *.zip", _
                                        MultiSelect:=False)
    If Fname = False Then
        'Do nothing
    Else
        'Root folder for the new folder.
        'You can also use DefPath = "C:\Users\Ron\test\"
        DefPath = Application.DefaultFilePath
        If Right(DefPath, 1) <> "\" Then
            DefPath = DefPath & "\"
        End If

        'Create the folder name
        strDate = Format(Now, " dd-mm-yy h-mm-ss")
        FileNameFolder = DefPath & "MyUnzipFolder " & strDate & "\"

        'Make the normal folder in DefPath
        MkDir FileNameFolder

        'Extract the files into the newly created folder
        Set oApp = CreateObject("Shell.Application")

        oApp.Namespace(FileNameFolder).CopyHere oApp.Namespace(Fname).items

        'If you want to extract only one file you can use this:
        'oApp.Namespace(FileNameFolder).CopyHere _
         'oApp.Namespace(Fname).items.Item("test.txt")

        MsgBox "You find the files here: " & FileNameFolder

        On Error Resume Next
        Set FSO = CreateObject("scripting.filesystemobject")
        FSO.deletefolder Environ("Temp") & "\Temporary Directory*", True
    End If
End Sub

Answer 2

是的，这可以使用VBScript编写脚本。例如，以下代码可以从目录创建zip：

Dim fso, winShell, MyTarget, MySource, file
Set fso = CreateObject("Scripting.FileSystemObject")
Set winShell = createObject("shell.application")


MyTarget = Wscript.Arguments.Item(0)
MySource = Wscript.Arguments.Item(1)

Wscript.Echo "Adding " & MySource & " to " & MyTarget

'create a new clean zip archive
Set file = fso.CreateTextFile(MyTarget, True)
file.write("PK" & chr(5) & chr(6) & string(18,chr(0)))
file.close

winShell.NameSpace(MyTarget).CopyHere winShell.NameSpace(MySource).Items

do until winShell.namespace(MyTarget).items.count = winShell.namespace(MySource).items.count
    wscript.sleep 1000 
loop

Set winShell = Nothing
Set fso = Nothing

您可能还会发现http://www.naterice.com/blog/template_permalink.asp?id=64很有帮助，因为它在VBScript中包含完整的Unzip / Zip实现。

如果每500毫秒进行一次尺寸检查而不是项目计数，则对大文件效果更好。 Win 7立即写入文件，虽然它没有完成压缩：

set fso=createobject("scripting.filesystemobject")
Set h=fso.getFile(DestZip)
do
    wscript.sleep 500
    max = h.size
loop while h.size > max

适用于大量日志文件。

Answer 3

为了清楚起见：GZip不是像Guy Starbuck在8月份的评论中所建议的仅限MS的算法。 System.IO.Compression中的GZipStream使用Deflate算法，与zlib库和许多其他zip工具相同。该类可以与像gzip这样的unix实用程序完全互操作。

GZipStream类不能从命令行或VBScript编写脚本，以生成ZIP文件，因此它不能解决原始海报的请求。

免费的DotNetZip库确实可以读取和生成zip文件，并且可以从VBScript或Powershell编写脚本。它还包括用于生成和读取/提取zip文件的命令行工具。

以下是VBScript的一些代码：

dim filename 
filename = "C:\temp\ZipFile-created-from-VBScript.zip"

WScript.echo("Instantiating a ZipFile object...")
dim zip 
set zip = CreateObject("Ionic.Zip.ZipFile")

WScript.echo("using AES256 encryption...")
zip.Encryption = 3

WScript.echo("setting the password...")
zip.Password = "Very.Secret.Password!"

WScript.echo("adding a selection of files...")
zip.AddSelectedFiles("*.js")
zip.AddSelectedFiles("*.vbs")

WScript.echo("setting the save name...")
zip.Name = filename

WScript.echo("Saving...")
zip.Save()

WScript.echo("Disposing...")
zip.Dispose()

WScript.echo("Done.")

以下是Powershell的一些代码：

[System.Reflection.Assembly]::LoadFrom("c:\\dinoch\\bin\\Ionic.Zip.dll");

$directoryToZip = "c:\\temp";
$zipfile =  new-object Ionic.Zip.ZipFile;
$e= $zipfile.AddEntry("Readme.txt", "This is a zipfile created from within powershell.")
$e= $zipfile.AddDirectory($directoryToZip, "home")
$zipfile.Save("ZipFiles.ps1.out.zip");

在.bat或.cmd文件中，您可以使用zipit.exe或unzip.exe工具。例如：

zipit NewZip.zip  -s "This is string content for an entry"  Readme.txt  src

Answer 4

这是我尝试总结压缩和解压缩的内置功能窗口 - How can I compress (/ zip ) and uncompress (/ unzip ) files and folders with batch file without using any external tools?

有几个给定的解决方案，几乎可以在每台Windows机器上运行。

关于 shell.application 和WSH，我更喜欢jscript 因为它允许混合批处理/ jscript文件（扩展名为.bat）不需要临时文件。我已经将解压缩和zip功能放在一个文件中，再加上一些功能。

Answer 5

在SourceForge（http://sourceforge.net/projects/unxutils）上提供的UnxUtils包中有zip和unzip可执行文件（以及其他有用应用程序的船载）。将它们复制到PATH中的某个位置，例如“c：\ windows”，您就可以将它们包含在脚本中。

这不是一个完美的解决方案（或者你要求的那个），而是一个体面的工作。
