File compression in linux

Compressing and decompressing tools:

1. zip and unzip

• zip: This is one of the most popular tools for creating compressed files in Linux. It packages files and directories into a single archive file with a .zip extension.

Usage: bash zip archive_name.zip file1 file2 dir1

• unzip: This tool is used to extract files from a .zip archive.

Usage: bash unzip archive_name.zip

2. tar

• tar: Short for Tape Archive, tar is commonly used to combine multiple files into a single file, known as a tarball, with extensions like .tar. While tar itself does not compress files, it is often used in conjunction with compression tools like gzip or bzip2.

Usage: bash tar -cvf archive_name.tar file1 file2 dir1

3. gzip and gunzip

• gzip: This tool compresses files using the GNU zip algorithm, typically resulting in .gz files.

Usage: bash gzip file1

• gunzip: This is used to decompress .gz files.

Usage: bash gunzip file1.gz

• Combining tar and gzip: bash tar -czvf archive_name.tar.gz file1 file2 dir1 tar -xzvf archive_name.tar.gz

4. bzip2 and bunzip2

• bzip2: This tool provides higher compression ratios than gzip, but it is slower. It results in files with a .bz2 extension.

Usage: bash bzip2 file1

• bunzip2: This is used to decompress .bz2 files.

Usage: bash bunzip2 file1.bz2

• Combining tar and bzip2: bash tar -cjvf archive_name.tar.bz2 file1 file2 dir1 tar -xjvf archive_name.tar.bz2

5. xz and unxz

• xz: This tool provides high compression ratios and is used to compress files to .xz format.

Usage: bash xz file1

• unxz: This is used to decompress .xz files.

Usage: bash unxz file1.xz

• Combining tar and xz: bash tar -cJvf archive_name.tar.xz file1 file2 dir1 tar -xJvf archive_name.tar.xz

6. 7z and p7zip

• 7z: This is the command-line version of the 7-Zip compression tool, providing high compression ratios. The files compressed by this tool typically have a .7z extension.

Usage: bash 7z a archive_name.7z file1 file2 dir1

• p7zip: This is a Unix port of 7-Zip, providing the 7z and 7za commands.

• 7z Extraction: bash 7z x archive_name.7z
