set -e, -u, -o, -x pipefail

The set lines

• These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing.
• With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.

• set -euxo pipefail is short for:

set -e
set -u

skhd config file location: ~/.config/skhd/skhdrc

Thinking behind these shortcuts:
Use 'cmd' key for all desktop,window,space related shortcuts. Here, cmd+alt is preferred to cmd+shift.
Use 'alt' key for all tmux related shortcuts.
Use 'ctrl', and leader key 'space' for vim related shortcuts.

Note: Most of the following shortcuts are configured for yabai.

#!/usr/bin/env sh
