One thought on “yum command examples

  1. Howdy Mate,

    Thanks for highlighting this and indicating about Linux IQ where more study and thought is necessary.

    I hear browser security should be taken seriously, which top extensions/add-on's do you guys use/recommend to make Firefox really safe when I am browsing, I am using Linux mint on my acer laptop to browse and email.
    All UNIX files have its description stored in a structure called ‘inode’. The inode contains info about the file-size, its location, time of last access, time of last modification, permission and so on. Directories are also represented as files and have an associated inode.
    Great effort, I wish I saw it earlier. Would have saved my day 🙂

    Thanks and Regards
