bunzip2, bzip2, and more

bzip2 and bunzip2 are two commands that are used for file compression and decompression on Unix-based systems. The bzip2 command is used to compress a file, while the bunzip2 command is used to decompress a file that has been compressed using bzip2. These commands are commonly used by system administrators to save disk space and to transfer large files between systems.

bzip2 is a powerful compression tool that compresses files using the Burrows-Wheeler block sorting text compression algorithm, followed by Huffman coding. This algorithm allows bzip2 to achieve a high level of compression while maintaining a relatively fast decompression time. This makes bzip2 ideal for compressing large files, such as backups, databases, and software distributions. When a file is compressed using bzip2, it is typically given a .bz2 extension. Here are a couple of examples to demonstrate this.
