LozanoMatheus / 01-bash_http.sh

Last active August 24, 2023 13:24

A simple request - HTTP request with native Bash and without curl/wget/*

	#!/usr/bin/env bash +x

	## Do you need to test your exposed app but you don't have curl/wget/* installed?

	## The ":" is a built-in command and it works similar to true. Let's say, ":" is more portable than "true"
	## Simple and easy
	:> /dev/tcp/localhost/22

	## Why using timeout? If any side has a firewall and it's dropping the packages, the request will take ~80 seconds to get the timeout.
