Error Initilize GIT  git init --initial-branch=main

> git init --initial-branch=main
error: unknown option `initial-branch=main'

regular code

cd existing_folder
git init --initial-branch=main
git remote add origin [email protected]:path/to/project.git
git add .
git commit -m "Initial commit"
git push -u origin main

to fix the problem you can use this way

The best easy way is to simulate the directory path, so lets assume you will need to fix the comparison page after you upgrade to Magento 2.3.5-p2

Filename: vendor/magento/module-catalog/Helper/Output.php

we need to replace this line 

- if (preg_match($pattern, $attributeHtml)) {

with this line 

+ if (preg_match($pattern, (string) $attributeHtml)) {

Now create those directories vendor/magento/module-catalog/Helper

This wiki will help you add specific directories in the parent directory 
Lets say you have two directories 

• app
• vendor

in "app" directory there are three folders

app/dir1
app/dir2
app/dir3
app/etc

in "vendor" directory there are three folders as well

vendor/dir1
vendor/dir2
vendor/dir3

you would like to add to GIT repository only these directory 

Get all bracnhes

git fetch --all
