📦 Linux Compression & Archiving Cheatsheet

🔧 Tar Command Basics

The tar command is used to create, extract, and manage archive files.

Syntax:

tar [options] [archive_name.tar] [file(s)/directory]

🛠 Create a .tar Archive

tar -cf archive_file.tar file1 file2 dir1

• -c: Create a new archive
• -f: Specify the archive file name

🛠 Create with Verbose Output

tar -cvf archive_file.tar file1 file2 dir1

• -v: Verbose mode (shows progress)

📂 Extract a .tar Archive

tar -xf archive_file.tar

tar -xvf archive_file.tar

• -x: Extract files

---

🗜 Gzip Compression

Gzip (GNU zip) is a fast, commonly used compression tool.

🔧 Create .tar.gz Archive

tar -czf archive_file.tar.gz file1 file2 dir1

• -z: Compress using gzip

🔧 Verbose Creation

tar -czvf archive_file.tar.gz file1 file2 dir1

📂 Extract .tar.gz

tar -xzf archive_file.tar.gz

tar -xzvf archive_file.tar.gz

---

🗜 Bzip2 Compression

Bzip2 offers better compression than gzip but is slower.

🔧 Create .tar.bz2 Archive

tar -cjf archive_file.tar.bz2 file1 file2 dir1

• -j: Compress using bzip2

🔧 Verbose Creation

tar -cjvf archive_file.tar.bz2 file1 file2 dir1

📂 Extract .tar.bz2

tar -xjf archive_file.tar.bz2

tar -xjvf archive_file.tar.bz2

---

🗜 XZ Compression

XZ provides the best compression ratios but is the slowest.

🔧 Create .tar.xz Archive

tar -cJf archive_file.tar.xz file1 file2 dir1

• -J: Compress using xz

🔧 Verbose Creation

tar -cJvf archive_file.tar.xz file1 file2 dir1

📂 Extract .tar.xz

tar -xJf archive_file.tar.xz

tar -xJvf archive_file.tar.xz

---
