How not to rm yourself

Copied from https://github.com/sindresorhus/guides/blob/master/how-not-to-rm-yourself.md

The rm command is inherently dangerous and should not be used directly. It can at worst let you accidentally remove everything. Here's how you can protect you from yourself.

Use trash

The trash command-line tool will move stuff to the trash instead of permanently deleting it. You should not alias rm to trash as it will break external scripts relaying on the behavior of rm. Instead use it directly: trash image.jpg.

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

The list would not be updated for now. Don't write comments.

The count of contributions (summary of Pull Requests, opened issues and commits) to public repos at GitHub.com from Wed, 21 Sep 2022 till Thu, 21 Sep 2023.

Because of GitHub search limitations, only 1000 first users according to amount of followers are included. If you are not in the list you don't have enough followers. See raw data and source code. Algorithm in pseudocode:
