How to install screenfetch on Ubuntu 16.10 to get your Linux system information in terminal

    screenFetch is a "Bash Screenshot Information Tool". This handy Bash script can be used to generate one of those nifty terminal theme information + ASCII distribution logos you see in everyone's screenshots nowadays. It will auto-detect your distribution and display an ASCII version of that distribution's logo and some valuable information to the right. There are options to specify no ASCII art, colors, taking a screenshot upon displaying info, and even customizing the screenshot command!

Screenfetch can display the following information:
  •     the name of your distro
  •     Linux kernel version
  •     uptime
  •     the number of installed packages on your system
  •     shell name and version
  •     screen resolution
  •     the name and version of your desktop environment
  •     font
  •     CPU, GPU and RAM info

Installation instructions:
    Open terminal from Unity Dash, App Launcher, or via Ctrl+Alt+T keys. When it opens, run below commands one by one:
$ sudo apt-add-repository ppa:djcj/screenfetch

$ sudo apt-get update

$ sudo apt-get install screenfetch

$ screenfetch

Running screenfetch

     To run screenFetch, open a terminal of some sort and type in the command screenfetch or wherever you saved the script to. This will generate an ASCII logo with the information printed to the side of the logo. There are some options that may be specified on the command line, and those are shown below or by executing screenfetch -h:

  -v                          Verbose output.
  -o 'OPTIONS'         Allows for setting script variables on the
                               command line. Must be in the following format...
  -d '+var;-var;var'   Allows for setting what information is displayed
                              on the command line. You can add displays with +var,var. You
                              can delete displays with -var,var. Setting without + or - will
                              set display to that explicit combination. Add and delete statements
                              may be used in conjunction by placing a ; between them as so:
  -n                         Do not display ASCII distribution logo.
  -N                         Strip all color from output.
  -w                         Wrap long lines.
  -t                          Truncate output based on terminal width (Experimental!).
  -p                         Output in portrait mode, with logo above info.
  -s [-u IMGHOST]    Using this flag tells the script that you want it
                              to take a screenshot. Use the -m flag if you would like
                              to move it to a new location afterwards.
  -c string                You may change the outputted colors with -c. The format is
                              as follows: [0-9][0-9],[0-9][0-9]. The first argument controls the
                              ASCII logo colors and the label colors. The second argument
                              controls the colors of the information found. One argument may be
                              used without the other.
  -a 'PATH'               You can specify a custom ASCII art by passing the path
                              to a Bash script, defining `startline` and `fulloutput`
                              variables, and optionally `labelcolor` and `textcolor`.
                              See the `asciiText` function in the source code for more
                              informations on the variables format.
  -S 'COMMAND'        Here you can specify a custom screenshot command for
                              the script to execute. Surrounding quotes are required.
  -D 'DISTRO'           Here you can specify your distribution for the script
                              to use. Surrounding quotes are required.
  -A 'DISTRO'            Here you can specify the distribution art that you want
                              displayed. This is for when you want your distro
                              detected but want to display a different logo.
  -E                         Suppress output of errors.
  -V, --version          Display current script version.
  -h, --help              Display this help.
