在下载时解压缩/打包tar文件?(是否可以流式传输?) [英] Untar/pack a tar file while downloading? (Is it streamable?)

问题描述

我很难弄清TAR文件是如何工作的.我希望构建一个在下载tar文件时提取其文件的应用程序.但是我似乎找不到与此主题有关的任何东西.

I have a hard time figuring out how a TAR file works. I wish to build an application that extracts a tar file while it's being downloaded. But I can't seem to find anything related to this subject.

这可能吗?TAR文件在内部如何工作?我有一点感觉，这是不可能的.

Is this possible? How does a TAR file internally work? I have a small feeling that this is not going to be possible.

推荐答案

建议:

curl -s https://example.com/dir/file.tar.gz | tar zx   #silent
curl https://example.com/dir/file.tar.gz | tar zx
curl https://example.com/dir/file.tar.gz | tar zvx     #view files while unpacked
curl https://example.com/dir/file.tar.gz | pv -s$BYTES | tar zx  #view progress

如果没有 curl 或 pv ，则可以使用 sudo apt install curl pv 或进行安装sudo yum install curl pv .

If you don't have curl or pv, you might be able to install with sudo apt install curl pv or sudo yum install curl pv.
