Introduction

Archiving and compression are essential skills for efficiently managing files on a Unix-like operating system. Tools such as zip, tar, gzip, bzip2, and xz are commonly used for these purposes. This guide provides detailed instructions on how to install, set up, and use these tools.

Installing Archiving and Compression Tools

Most archiving and compression tools come pre-installed on Unix-like systems. However, if they are not available, you can install them using your package manager.

Ubuntu/Debian

sudo apt update
sudo apt install zip unzip tar gzip bzip2 xz-utils -y

CentOS/RHEL

sudo yum install zip unzip tar gzip bzip2 xz -y

Fedora

sudo dnf install zip unzip tar gzip bzip2 xz -y

Using zip

Creating a Zip Archive

To create a zip archive, use the following command:

zip archive_name.zip file1 file2 dir1

Extracting a Zip Archive

To extract a zip archive, use:

unzip archive_name.zip

Listing Contents of a Zip Archive

To list the contents of a zip archive without extracting:

unzip -l archive_name.zip

Adding Files to an Existing Zip Archive

To add files to an existing zip archive:

zip archive_name.zip newfile1 newfile2

Using tar

Creating a tar Archive

To create a tar archive, use the following command:

tar -cvf archive_name.tar file1 file2 dir1

Extracting a tar Archive

To extract a tar archive, use:

tar -xvf archive_name.tar

Listing Contents of a tar Archive

To list the contents of a tar archive without extracting:

tar -tvf archive_name.tar

Creating a Compressed tar Archive with gzip

To create a tar archive compressed with gzip:

tar -czvf archive_name.tar.gz file1 file2 dir1

Extracting a Compressed tar Archive with gzip

To extract a tar archive compressed with gzip:

tar -xzvf archive_name.tar.gz

Using gzip

Compressing a File

To compress a file with gzip:

gzip file1

Decompressing a File

To decompress a file with gzip:

gunzip file1.gz

Keeping the Original File After Compression

To compress a file and keep the original file:

gzip -k file1

Using bzip2

Compressing a File

To compress a file with bzip2:

bzip2 file1

Decompressing a File

To decompress a file with bzip2:

bunzip2 file1.bz2

Keeping the Original File After Compression

To compress a file and keep the original file:

bzip2 -k file1

Using xz

Compressing a File

To compress a file with xz:

xz file1

Decompressing a File

To decompress a file with xz:

unxz file1.xz
