Ignore whole Directory and allow only some folders

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 

app/dir1
app/dir2
vendor/dir3

in this case you need to add this code to your .gitignore file

!/app
/app/*
!/app/code
!/app/design

!/vendor
/vendor/*
!/vendor/lesite
!/vendor/mirasvit

now if you want to allow the directory and ignore one file (EX. env.php) you need to add this 

!/app/etc
/app/etc/env.php

the whole file will be 

 

/*
!/app
/app/*
!/app/code
!/app/design
!/app/etc
/app/etc/env.php
!/vendor
/vendor/*
!/vendor/lesite
!/vendor/mirasvit
