[Sheflug] Sheffetch.sh

Hi All,

Just for fun I was trying to make a very simple Neofetch equivalent in bash.

Neofetch - https://github.com/dylanaraps/neofetch
and this was before I found screenfetch
https://github.com/KittyKatt/screenFetch

I managed to get

#!/bin/bash

totalmem=$(free -m | grep -oP '\d+' | head -n 1)
currmem=$(free -m | grep -oP '\d+' | head -n 2 | tail -1)

echo "$(whoami)@$(hostname)"
echo "Distro:        $(hostnamectl | grep Operating| cut -d" " -f3-)"
echo "Kernel:        $(uname -r)"
echo "Uptime         $(uptime -p | cut -d" " -f2-)"
echo "Shell:         $SHELL"
echo "Processes:     $(ps -e | wc -l)"
echo "Memory:        $currmem | $totalmem"
echo "Resolution:    $(xrandr --current | grep "[*]" | uniq | awk '{print
$1}')"
echo "WM:            $XDG_CURRENT_DESKTOP"
echo "Terminal:      $TERM"
echo "Terminal Font: $(grep FONTFACE < /etc/default/console-setup | cut -d
'"' -f 2)"
echo "CPU:           $(grep name < /proc/cpuinfo | head -n1 | tr -s ' ' |
cut -d" " -f3-)"
echo "GPU:           $(lspci | grep VGA | head -n1 | cut -d" " -f5-)"

echo -e
"\e[30m\u2588\e[31m\u2588\e[32m\u2588\e[33m\u2588\e[34m\u2588\e[35m\u2588\e[36m\u2588\e[37m\u2588\e[0m"
echo -e
"\e[1;30m\u2588\e[1;31m\u2588\e[1;32m\u2588\e[1;33m\u2588\e[1;34m\u2588\e[1;35m\u2588\e[1;36m\u2588\e[1;37m\u2588\e[0m"

Is there anything I should obviously avoid in the above? I did start to
remove echo and replace with printf but I think echo -e is allowed
everywhere these days.
Is there any information that is missing such as Display server.

I think the code for that would be

if [[ -z "$WAYLAND_DISPLAY" ]]
then
     echo "Display Server:$XDG_SESSION_TYPE"
else
     echo "Display Server:$WAYLAND_DISPLAY"
fi

The last two lines change the ink colour with \e[nnm and print a unicode
full block \u2588 and finally reset ink colour to default with \e[0m
The \e[1;nnm just switches on bold for that colour. I initially had
difficulties because in my case Gnome-Terminal sets the default yellow to
be a light brown colour if running without a profile but XTerm was fine.

Regards
John
