如何从 bz2 存档中获取文件列表（ls 命令）？

Question

从.bz2类型的存档文件（ .bz2压缩存档）获取文件列表（如ls ）的 Unix bash 命令是什么？

Answer 1

First bzip2 , gzip , etc compress only one file. So probably you have compressed tar file. To list the files you need command like:

tar tjvf file.bz2

This command uncompress the archive and test the content of tar .

Answer 2

Note that bzip2 compresses each file, and a simple .bz2 file always contains a single file of the same name with the ".bz2" part stripped off. When using bzip2 to compress a file, there is no option to specify a different name, the original name is used and .bz2 appended. So there are no files, only 1 file. If that file is a tar archive, it can contain many files, and the whole contents of the .tar.bz2 file can be listed with "tar tf file.tar.bz2" without unpacking the archive.
