How to Extract (Unzip) Tar Bz2 File

The tar command allows you to create and extract tar archives. It supports a vast range of compression programs such as gzip, bzip2, lzip, lzma, lzop, xz and compress.

Bzip2 is one of the most popular algorithms for compressing tar files. By convention, the name of a tar archive compressed with bzip2 ends with either .tar.bz2 or .tbz2.

In this tutorial, we will explain how to extract (or unzip) tar.bz2 and tbz2 archives using the tar command.

Extracting tar.bz2 File

Most Linux distributions and macOS comes with the tar utility pre-installed by default.

To extract a tar.bz2 file, use the --extract (-x) option and specify the archive file name after the -f option:

tar -jf archive.tar.bz2

The tar command auto-detects compression type and extracts the archive. The same command can be used to extract tar archives compressed with other algorithms such as .tar.gz.

If you are a Desktop user and the command-line is not your thing you can use your File manager. To extract (unzip) a tar.bz2 file simply-right click the file you want to extract and select “Extract”. Windows users will need a tool named 7zip to extract tar.bz2 files.

For more verbose output use the -v option. This option tells tar to display the names of the files being extracted on the terminal.

tar -xvf archive.tar.bz2

By default, tar will extract the archive contents in the current working directory. Use the --directory (-C) to extract archive files in a specific directory:

For example, to extract the archive contents to the /home/linuxize/files directory, you would type:

tar -jf archive.tar.bz2 -C /home/linuxize/files

Extracting Specific Files from a tar.bz2 File

To extract a specific file(s) from a tar.bz2 file, append a space-separated list of file names to be extracted after the archive name:

tar -jf archive.tar.bz2 file1 file2

When extracting files, you must provide their exact names including the path, as printed when the --list (-t) option is used.

Extracting one or more directories from an archive is the same as extracting multiple files:

tar -jf archive.tar.bz2 dir1 dir2

If you try to extract a file that doesn’t exist in the archive, an error message similar to the following will be shown:

tar -jf archive.tar.bz2 README
tar: README: Not found in archive
tar: Exiting with failure status due to previous errors

The --wildcards option allows you to extract files from a tar.bz2 file based on a wildcard pattern. The pattern must be quoted to prevent the shell from interpreting it.

For example, to extract only the files whose names end in .md (Markdown files), you would use:

tar -jf archive.tar.bz2 --wildcards '*.md'

Extracting tar.bz2 File from stdin

When extracting a compressed tar.bz2 file by reading the archive from standard input (usually through piping), you must specify the decompression option. The -j option tells tar that the file is compressed with bzip2.

In the example below we are downloading the Vim sources using the wget command and pipe its output to the tar command:

wget -c ftp://ftp.vim.org/pub/vim/unix/vim-8.1.tar.bz2 -O - | sudo tar -xj

If you don’t specify a decompression option, tar will show you which option you should use:

tar: Archive is compressed. Use -j option
tar: Error is not recoverable: exiting now

Listing tar.bz2 File

To list the content of a tar.bz2 file, use the --list (-t) option:

tar -tf archive.tar.bz2

The output will look something like this:

file1
file2
file3

If you add the --verbose (-v) option, tar will print more information, such as owner, file size, timestamp ..etc:

tar -tvf archive.tar.bz2
-rw-r--r-- linuxize/users       0 2019-02-15 01:19 file1
-rw-r--r-- linuxize/users       0 2019-02-15 01:19 file2
-rw-r--r-- linuxize/users       0 2019-02-15 01:19 file3

Conclusion

tar.bz2 file is a Tar archive compressed with Bzip2. To extract a tar.bz2 file, use the tar -jf command followed by the archive name.
