Linux File Compression Guide

In Linux systems, there are several commands that can be used to compress and decompress files, commonly used ones include rar, tar, bz, and gz. Below are detailed explanations and usage instructions for them.

1. RAR: RAR is an archive file format that allows you to compress and decompress files. The command to compress files using the RAR command is: rar a compressedfilename.rar file or folder to be compressed. For example, to compress the folder “example” into “example.rar”, you can use the command: rar a example.rar example. The command to decompress files using the RAR command is: rar x compressedfilename.rar. For example, to extract “example.rar”, you can use the command: rar x example.rar.
2. Tar is a file archiving tool commonly used to package multiple files or folders into one file. To compress files using the tar command, the command is: tar -cvf compressed_filename.tar files_or_folders_to_compress. For example, to compress the folder “example” into “example.tar”, you can use the command: tar -cvf example.tar example. To extract files using the tar command, the command is: tar -xvf compressed_filename.tar. For example, to extract “example.tar”, you can use the command: tar -xvf example.tar.
3. Bz is a file compression algorithm commonly used to compress files into .bz files. To compress a file using the bz command, the command is: bzip2 filename. For example, to compress a file named “example” into “example.bz”, you can use the command: bzip2 example. To decompress a file using the bz command, the command is: bunzip2 filename.bz. For example, to decompress “example.bz”, you can use the command: bunzip2 example.bz.
4. Gzip is a file compression algorithm commonly used to compress files into .gz format. The command to compress a file using gzip is: gzip filename. For example, to compress the file “example” into “example.gz,” you can use the command: gzip example. The command to decompress a file using gzip is: gunzip filename.gz. For example, to decompress “example.gz,” you can use the command: gunzip example.gz.

These commands are built-in tools in the Linux system that can be used by entering them in the terminal.
