将.xip文件解压缩到特定文件夹中 [英] Extract .xip files into a specific folder

问题描述

XIP 文件是zip的模拟，但允许在扩展归档之前在接收系统上应用和验证数字签名.当打开 XIP 文件(通过双击)时，Archive Utility会自动将其展开(但前提是数字签名完好无损).

A XIP file is an analog to zip, but allows for a digital signature to be applied and verified on the receiving system, before the archive is expanded. When a XIP file is opened (by double-clicking), Archive Utility will automatically expand it (but only if the digital signature is intact).

本质上，.xip文件只是带有签名的.zip文件，用于验证自文件创建者保存文件以来该文件没有更改.这样既可以防止磁盘错误损坏，也可以防止第三方篡改文件.

Essentially, a .xip file is just a .zip with a signature to verify that the file has not changed since its creator saved it. This protects from both damage from a disk error and from a third-party tampering with the file.

有人知道如何提取此文件，例如使用终端到特定文件夹，而不是.xip文件所在的文件夹?

Does anyone know, how to extract this file, e.g. using Terminal, to a specific folder instead of to the folder where the .xip file resides?

推荐答案

也许尝试:

xip -x [path to .xip file]

这会将压缩文件解压缩到您当前的工作目录中.

That will unpack the archive into your current working directory.

对于提取到特定目录中，没有明确的选项，但是xip -x将提取到当前工作目录中.因此，cd到您要提取文件的位置应该可以；如果您特别需要自动执行此操作，请使用以下脚本:

As for extracting into a specific directory, there is not explicitly an option for this, but xip -x will extract into the current working directory. Therefore, cding to where you would like to extract the file should work; if you specifically need to automate this, a script to the effect of:

#!/bin/sh

xipfile="$(cd $(dirname "$1"); pwd -P)/$(basename "$1")" # a portable "realpath"

cd "$2"
xip -x "$xipfile"

我想怎么做?
