system info practice script

Just thought i would share this here and ask a question or two..be mindful im only learning and hope to improve.

This is just a practice script to show system info but in a very basic way, has nothing on programs like neofetch or screenfetch etc.

So below is my effort so far and just want to know if this would work on your devuan system ok. Also id like to figure out a better method of displaying the window manager instead of using wmctrl, like something in coreutils.

Anyhow, needs bash and wmctrl as a dependency and is only work for devuan, i hope wink

#!/usr/bin/env bash

titles=('\e[1;34m%-6s\e[m\t') # blue titles
line=('\e[1;31m%-37s\e[m\n') # red line

printf "\n"

printf "\t" ; echo "$(whoami)@$(hostname)"

printf  $line | tr ' ' -

printf  $titles "os:" ; cat /etc/os-release | awk 'NR==1' | sed 's/............//;s/.//;s/.$//g'

printf  $titles "kernel:" ; uname --kernel-release

printf  $titles "uptime:" ; uptime -p | sed 's/^...//g'

printf  $titles "pkgs:" ; dpkg -l | wc -l

printf  $titles "memory:" ; free -mh | awk 'NR==2 {print $3" / "$2}'

printf  $titles "wm:" ; wmctrl -m | awk 'NR==1 {print $2}'

printf  $titles "shell:" ;  echo $SHELL

printf  $titles "editor:" ; echo $EDITOR

echo $'\e7\e[2;800H\e[16D\e[7m' $(date +"%Y/%m/%d %H:%M")$'\e8'

printf "\n"

prints out this with some colors and stuff like so.

Re: system info practice script

just want to know if this would work on your devuan system

It works pretty good here.  I noticed the editor line at the bottom was empty though.  Is that because I do not have a default editor configured?

I did have to install wmctl as it was not installed.

Re: system info practice script

Thanks nixer,

yeah if you havent got $EDITOR configured in .bashrc i dont think the script will display editor.

just put this in your bashrc

export EDITOR='vim'

replace vim for whatever editor you like.

cheers

Re: system info practice script

Works for me, but I had to install the wmctrl package as it's not there by default.

Re: system info practice script

Works here on my beowulf. I didn't feel like installing wmctrl, so I changed that line to

printf  $titles "wm:" ; basename $(cat /etc/X11/default-display-manager)

You don't need cat:

printf  $titles "os:" ; awk 'NR==1' /etc/os-release | sed 's/............//;s/.//;s/.$//g'

Or with awk alone:

printf  $titles "os:" ; awk -F'"' '/PRETTY/{print $2}' /etc/os-release
HevyDevy wrote:
printf  $titles "pkgs:" ; dpkg -l | wc -l

That will return a slightly larger number because the dpkg output prints an information section and also lists some non-installed packages, try this instead:

printf  $titles "pkgs:" ; dpkg -l | grep -c '^ii'

Nice, thanks Hoas. I was thinking that cat was not needed.

Re: system info practice script

Works here. Installed wmctrl to show fluxbox, then saw fsmithred's edit and tried it. The difference: wmctrl capitalizes the 'F' in fluxbox, default-display-manager doesn't. wink
