remove some major annoyances:

TERM setting that is more compatible with most real world apps
!= should be displayed as two characters, not one
don't ask when closing a tab (= don't block shutdowns/reboots)

#   ~/.config/ghostty/config

# https://github.com/ghostty-org/ghostty/discussions/3161
command = TERM=xterm-256color /usr/bin/bash

urldump() {
sudo tcpdump -i any -A -s 0 -l 'tcp' | awk '/GET|POST|PUT|DELETE|HEAD|OPTIONS|PATCH.*HTTP/ {match($0, /(GET|POST|PUT|DELETE|HEAD|OPTIONS|PATCH) ([^ ]+)/, arr); method=arr[1]; url=arr[2]} /^Host:/ {if(method) {print method, $2 url; method=""}}'}

Powershell pure text grep (`grepp`)

what

A grep command (grepp) in Powershell that lets you grep for a string in the text that would usually be printed in the terminal (not some other representation of the data). Output is a string, not a pipeline anymore - thus destructive.

why

To quickly grep through shell output without having to do where-object gymnastics.
