Installing Software on Command Line

  1. 2. Installing Software on Terminal

    To Search & Install Packages on Terminal
    First, you can use the default Apt Package Manager
    Now to Search for Packages with Keyword use:

    sudo apt search [myKeyword]

    Replace “[myKeyword]” with your searching Keyword in the above.
    Use the “–help” flag to show up the available Commands.
    And in older releases “apt search” is replaced by “apt-cache”.

    And then to Install a Debian Package play:

    sudo apt install [myPackage]

    As a replacement working also on older Releases you can use the “apt-get” Tool.
    Authenticate with the User Admin Pass.
    If Got “User is Not in Sudoers file” then see: How to Enable sudo.
    As an advanced Alternative you may use the Aptitude Software!
    To Install it play:

    sudo apt install aptitude

    Then you can use it with a similar Syntax as for apt…
    So to get Help symply:

    aptitude --help
