HTTPX Troubleshooting Issue

Hello everyone, In this article, I’m addressing a frequently encountered error: “No such option: -l in httpx”. Many of us have stumbled upon this issue and, like you, I’ve searched for solutions. The error typically occurs when attempting to use the “-l” string, which is commonly employed when you have a list of hosts that you want httpx to process. Let’s dive into why this error occurs and how we can resolve it.

Before revealing the straightforward solution (which is surprisingly simple), let’s take a moment to briefly discuss what httpx is and the advantages it offers. For those eager to jump straight to the solution, feel free to scroll down to the section titled “Resolving the Issue”. A quick note: my explanations are based on the Kali Linux installation of httpx, rather than the GitHub version.

What is HTTPX?

"httpx" is a fast and multi-purpose HTTP toolkit that allows running multiple probes using the retryablehttp library. It is designed to maintain result reliability with an increased number of threads.”
