ScreenFetch

ScreenFetch is a Bash Screenshot Information Tool, that generates terminal information and ASCII distribution logos.  After seeing it somewhere, I thought I would have to try it out.  I'm glad I did.

There are several ways that this can be installed, here is one I elected to use.

yum install -y git
cd /opt
git clone https://github.com/KittyKatt/screenFetch.git
cd screenFetch/
chmod +x screenfetch-dev
./screenfetch-dev

After ensuring that it runs, I updated the man page and added to the other man pages.

./udpate-manpage.sh
gzip screenfetch.1
cp screenfetch.1.gz /usr/share/man/man1
man screenfetch
makewhatis

To make the script run each time someone logs into the system add a script to the profile.d directory.  Using vim, create a file /etc/profile.d/screenfetch.sh.

#!/bin/bash
printf "\n"
/opt/app/screenFetch/screenfetch-dev

Make the file executable and active.

chmod +x /etc/profile.d/screenfetch.sh
source /etc/profile.d/screenfetch.sh

The next time someone logs into the system, in this case, CentOS, a screen similar to this should present itself.

screenfetchThere is a small delay as this script collects all the information, but there is a way to reduce the delay by deselecting some of the options.  Using the same /etc/profile.d/screenfetch.sh file, options may be appended to the command, like so.

#!/bin/bash
printf "\n"
/opt/screenFetch/screenfetch-dev -d '-host;-res;-de;-wm;-gtk;-gpu'

For this example, I removed the host, Resolution, WM, the GTK Theme, and GPU.  This significantly reduced the delay.
