How to remove some letters form a variable in bash

I have this Url

Https://github.com/RayaneQH/test.git

I want to write a bash script that take this input and output only the test (the repository)
Note:
If there is any way to do this using git , i prefer that you give the two solutions , one in bash and one in git

I google it and i didn't find anything

You can use parameter expansion of your shell to remove the largest prefix pattern:

url='https://github.com/RayaneQH/test.git'
url="${url##*/}"

This will remove everything up to and including the final slash.

I don't know how this could be done with Git, since Git is a version control system and not a scripting language.

"with git"

Using the github API with the github CLI

gh api 'repos/RayaneQH/test' --jq '.name'

would output (if the repo existed)

test

Omit the --jq option to get all data about the repo in JSON format.
