i3 status_command script
This script provides a (theoratically shell agnostic) way to retrieve system information and provide them for i3wm's status bar.
This script is by no means correct nor the most efficient one. It also is kinda hacked for my device(s) to work and thus you might have to change a lot to get it to work for you.
Just put status_command sh path/to/bar.sh into your i3
bar configuration block.
- easily extensible
- change existing functions or
- just write your own
- uses
.Xresources-colors (if you actually remove the overrides) - updates on each second (theoratically)
- should be POSIX shell compatible (I'm to lazy to actually test this)
- handcrafted for my system (Arch Linux, minimalistic, Lenovo T450s)
- does not seem to need too much resources
The bar allows to view different "modules" (if you can really call them that). Currently there are implementations for the following:
| Module | Benefit |
|---|---|
music |
Which tunes again? |
wlan <iface> |
No need for ping google.com. |
vpn |
Is the VPN up? |
disk <dir> |
Don't download that much... |
memory |
Browsers and their RAM. |
temperature |
Admit it: you can hear the fan... |
cpu |
The heat isn't indicator enough? |
brightness |
xbacklight was yesterday |
layout |
xkblayout-state ftw |
leds |
EVERYTHING IS WRONG11! |
volume |
Sound? What's that? |
battery <num> |
Need to recharge again? |
clock |
On time. |
Each module produces its own text, while the colour depends
on the functions return-value. The colours can be changed as
documented in jsonfy.
Currently the script requires read/write access to
/tmp/barsh.cpu.tmp for the CPU-load calculations. The
filepath can be adjusted. Maybe I will fix this at some
point...
This uses probably many PIDs. Which should not matter, as they are available right after, but maybe you got a more fragile system.
Turns out, this script is not as POSIX compliant as intended. I will try to sort this out eventually...
Do whatever you want, but please remember to mention me as the original author (should probably be a GPL or MIT).
