.bz2 is a compressed file created with bzip2 utility in Linux. Extracting these type of files is straight-forward in Linux, but in order to extract the file to another directory, you need to apply some options. Type the following command in Linux terminal:
$ bzip2 -dc your-file.bz2 > folder/your-file
dstands for decompress
ctells bzip2 to output the decompressed content to the standard output
In this command we forward the standard output to the specific file in another directory
folder/your-file. This also leaves the original .bz2 file unchanged. Also, note that the folder
folder must exists before using this command.
