- for downloading packages from arch archive
	```sh
	#!/bin/bash

	# Check if the input file is provided
	if [ -z "$1" ]; then
	  echo "Usage: $0 <file_with_package_names>"
	  exit 1
	fi

	# Check if the file exists	
	if [ ! -f "$1" ]; then
	  echo "File '$1' not found!"
	  exit 1
	fi

	# Read the file line by line
	while IFS= read -r package; do
	  # If the line is not empty
	  if [ -n "$package" ]; then
		# Construct the URL based on the pattern
		url="https://archive.archlinux.org/packages/${package:0:1}/$package"

		# Output the URL
		echo "Downloading: $url"

		# Download the package using wget
		wget "$url"
	  fi
	done < "$1"

	```
	(this one is not working)
	Running it:
	`bash download_packages.sh packages.txt`
	Then to install these all
	`sudo pacman -U $(< packages.txt)`
	or
	`sudo pacman -U *.zst`
	
	new one
