5 Advanced Command Line Archive Tools for Linux - Part 2

This article expands on our previous exploration of top command-line archive tools, adding five more powerful utilities to your Linux arsenal. We'll cover their features, options, and practical examples.

6. bzip2: Enhanced Compression

bzip2 leverages the Burrows-Wheeler algorithm and Run-Length Encoding (RLE) for superior compression compared to gzip, creating .bz2 files.

Key Options:

• -d: Decompression.
• -z: Compression (default).
• -k: Preserve the original file.
• -f: Force overwrite.

Examples:

Compress: bzip2 myfile.txt

Decompress: bzip2 -d myfile.txt.bz2

Compress & Keep Original: bzip2 -k myfile.txt

7. xz: Exceptional Compression for Large Files

xz utilizes the LZMA2 algorithm, excelling at compressing large files with higher ratios than gzip and bzip2, resulting in .xz archives.

Key Options:

• -d: Decompression.
• -k: Keep original file.
• -z: Compression (default).
• -f: Force overwrite.

Examples:

Compress: xz largefile.dat

Decompress: xz -d largefile.dat.xz

Compress & Keep Original: xz -k largefile.dat

8. zip: Cross-Platform Archiving

zip is a ubiquitous archiving tool, creating single .zip archives for easy cross-platform sharing.

Key Options:

• -r: Recursive archiving of directories.
• -u: Update existing archives.
• -d: Delete files from the archive.
• -m: Move files into the archive, deleting originals.

Examples:

Create Archive: zip myarchive.zip file1.txt file2.jpg

Compress Directory Recursively: zip -r myarchive.zip mydirectory/

Extract: unzip myarchive.zip

9. rar: Robust Archiving with Advanced Features

rar, a proprietary utility, is known for its strong compression of large files and supports password protection and multi-volume archives.

Key Options:

• a: Add files.
• x: Extract files.
• v: Create multi-volume archives.
• p: Set a password.

Examples:

Create Archive: rar a myarchive.rar document1.pdf image1.png

Extract: rar x myarchive.rar

Create Password-Protected Archive: rar a -p myarchive.rar importantdata.txt

10. 7z (7-Zip): High-Compression Powerhouse

7z employs the LZMA algorithm for superior compression, generating .7z files.

Key Options:

• a: Add files.
• x: Extract files.
• l: List archive contents.
• d: Delete files from the archive.

Examples:

Create Archive: 7z a myarchive.7z datafile1.db config.ini

Extract: 7z x myarchive.7z
