用 tar 覆盖文件
我试图压缩一个文件并最终覆盖它。 我正在 Xcode 中工作，我想知道是否有办法恢复被覆盖的文件。
I was trying to tar a file and ended up overwriting it. I was working in Xcode and I'm wondering if there is a way for me to recover the overwritten file.

除非你把它保存在其他地方，否则不太可能。 对不起
Unless you saved it somewhere else, its unlikely. sorry
是的，来自您的备份，当然，您经常定期进行备份，对吧？
转念一想，你可能不会，所以你运气不好。
我认为这是一个改变备份实践的机会:-)。
Yes, from your backups which, of course, you do regularly and frequently, right?
On second thoughts, you probably don't, so you're fresh out of luck.
I'd look on this as an opportunity to change your backup practices :-).
如果您的意思是在 tar 存档中添加了同一个文件两次，那么您很可能可以恢复它：tar 永远不会覆盖，它会附加。 并且在提取它时提取两者，这可能会导致覆盖。
如果您的意思是从 tar 存档中提取了一个文件并在此过程中覆盖了另一个文件，那么不幸的是您唯一的机会就是备份。 也许您的 Mac 上已安装 Time Machine，或者您正在使用 SCM 来执行开发任务。
If you mean that you added the same file twice in a tar archive, chances are that you can recover it: tar never overwrite, it appends. And when extracting it extract both which may result in an overwrite.
If you mean that you extracted a file from a tar archive and overwrote another in the process, unfortunately your only chance is backups. Maybe Time Machine is up on your Mac or you are using a SCM for your developer tasks.
