This article details how to compress directories using the `tar` and `gzip` commands in Ubuntu's terminal for efficient disk space management. It explains the use of `tar` for creating archives that preserve file permissions and `gzip` for compression, offering better ratios compared to other utilities like zip. The guide covers basic command usage such as creating an uncompressed archive with `tar cvf`, adding gzip compression using `-z`, and utilizing bzip2 (`-j`) for even greater compression at the cost of speed. Additionally, it includes instructions on extracting tarballs, handling sparse files, compressing individual files, specifying custom compression levels, and listing contents without extraction. The article concludes by recommending further exploration through manual pages to deepen understanding of these powerful tools.

This article provides a comprehensive guide on compressing directories using `tar` and `bzip2` in the terminal on an Ubuntu system. It explains how to create tar archives of multiple files and directories, then further reduce their size with bzip2's advanced compression techniques. The tutorial covers installation of necessary tools if not pre-installed, creation of a tar archive (`tar -cvf backup.tar .`), compressing it with `bzip2`, verifying the compressed file (`ls -lh backup.tar.bz2`), and extracting files using both `bunzip2` and `tar`. It also includes advanced options like direct compression during archiving, specifying different bzip2 compression levels, avoiding temporary files during compression, and troubleshooting common errors related to permissions or incomplete archives.
