7z

An open-source archive software with a high compression ratio.

Installation

Run the following command in Linux to install 7-Zip.

# Ubuntu systems
apt-get update
apt-get install p7zip-full -y

# CentOS    Reference: https://linuxconfig.org/how-to-install-p7zip-on-redhat-8
sudo yum install epel-release
yum install p7zip p7zip-plugins

Examples

Common scenarios: extraction, compression, and viewing (archive contents).

Extract the archive text.7z to the current directory.

7z x text.7z

Extract the archive text.7z to a specific directory (/home/text).

# Note: -o is used to specify the output directory. There is no space between -o and the directory path.
7z x text.7z -r -o/home/text

Extract specific files/folders (dir1/dir2 and dir1/file1) from text.7z to a specific directory (/home/text), maintaining the original path structure.

# Note: dir1/dir2 and dir1/file1 are the paths of files or folders within the archive.
7z x text.7z dir1/dir2 dir1/file1 -o/home/text

Compress the directory /home/text into text.7z.

7z a text.7z -r /home/text

View the contents of text.7z without extracting.

7z l text.7z
