bcc VS exa

But wait, there's more! Enter the BCC toolkit and library, your trusty sidekick in simplifying the arcane art of writing eBPF applications. With BCC by your side, you'll be wielding eBPF like a seasoned pro in no time.

Nice - I normally use [bash-readline](https://github.com/iovisor/bcc/blob/master/tools/bashreadlin...) when coworking/co-inhabiting a server or training someone.

One of the big wins is not so much “build and run your own stuff” but there are very nice low-cost (in terms of compute) performance utilities built on eBPF

There are so many utilities in that list; there’s a diagram midway down the readme which tries to help show their uses. bcc-tools should be available in any distro.

Also, Brendan Gregg does a ton of performance stuff that is worth knowing about if you check out his other work. Not eBPF only. Flame graphs are useful.

In this article, we'll build a basic version of an HTTPS sniffer, inspired by bcc-sslsniff.py, but we'll use Rust and Aya. We're going to demonstrate the capabilities of uprobes by employing uprobe and uretprobe along with familiar maps like PerCpuArray, HashMap, and PerEventArray. This will be a straightforward example to help us explore how uprobes function.

As xpd program I am using the BCC example xdp_redirect_map.py in skb mode as my NIC does not support native mode, attaching the program to veth2 and a dummy function to veth3

It depends on the scale of the project but man, if you can't build a simple CRUD app in your preferred stack and deploy it in some fashion (even if it's just a binary posted on some website, kinda like Exa) then that's just disappointing...

Can compile to a single binary to build tools like exa

Try https://github.com/ogham/exa and exa -T -L2 command . It will generate a good folder structure tree to update the question

Some of us don't want all of GNU's utilities; just on an as-needed basis. They're not as needed as they once were.

Many of these utilities have been rewritten in Rust and have more modern features.

For example, instead of ls, I use exa [1]. Or ripgrep [2] instead of grep.

fish: A very fast shell with various customization options to streamline daily commands. I discovered it through this post by @caarlos0, where he provides more details about performance and the differences between fish and zsh. Additionally, I use some CLI utilities like delta, exa, and ripgrep. Here's my dotfiles for fish.

Hi! I use this: https://the.exa.website, and the package to this: https://archlinux.org/packages/extra/x86_64/exa/

I still use exa for listing files in the terminal. It's a modern replacement for ls with a lot of useful features. With icons, colors, and git integration, it makes listing files much nicer.
