A 7-Zip file with the extension .7z is a compressed file format that can be extracted using p7zip tool in Linux. p7zip is available for most Linux systems and can easily be installed at the terminal. Once installed, 7-Zip files can then be extracted from the terminal or supporting GUI-based file explorer applications such as Nautilus for GNOME or Dolphin for KDE.

    Need to get 1,546 kB of archives.
    After this operation, 5,908 kB of additional disk space will be used.
    ##### snipped
    $ sudo yum install --assumeyes epel-release && sudo yum install --assumeyes p7zip # CentOS and Red Hat
  3. Create folder where you want to extract the file onto (optional).
    $ mkdir target_directory
  4. Go to the target directory where you want to extract the file onto (optional).
    $ cd target_directory
  5. Extract using 7z command.
