There are a couple of places in the documentation where `/bin/bash` are referenced (this doesn't exist on NixOS). For compatibility, change these to `/usr/bin/env bash`. Leave `/bin/sh` intact as it isn't an issue.

Hyprland exposes two powerful sockets for you to use.
The first, socket1, can be fully controlled with hyprctl, see its usage
here.
The second, socket2, sends events for certain changes / actions and can be used to react to different events. See its description here.
Example script
This bash script will change the outer gaps to 20 if the currently focused monitor is DP-1, and 30 otherwise.
#!/usr/bin/env bash
function handle {
if [[ ${1:0:10} == "focusedmon" ]]; then
if [[ ${1:12:4} == "DP-1" ]]; then
hyprctl keyword general:gaps_out 20
else
hyprctl keyword general:gaps_out 30
fi
fi
}
socat - "UNIX-CONNECT:/tmp/hypr/$HYPRLAND_INSTANCE_SIGNATURE/.socket2.sock" | while read -r line; do handle "$line"; done
