2、zstd格式解压缩命令

扩展名.zst表示存档由zstd压缩。
tar命令有一个选项-I（ -  use-compress-program）来指定压缩/解压缩命令。
解压命令:
$ tar -I zstd -xvf filename.tar.zst
压缩命令
$ tar -I zstd -cvf filename.tar.zst files

实例应用:

#压缩命令实例
imaginemiracle@:$ tree

imaginemiracle@:$ tar -I zstd -cvf zstd_test.tar.zst zstd_test/

imaginemiracle@:$ ls
