A small list of most common git commands I use (Is really important keep it saved, because sometimes it save us time of search on official documentations and forums.... :))

git_commands

-----  git rm -r --cached <folder_name>  
     
    It discard of git index but not from local working copy...useful when by accident we pushed something to remote repository and then we have to remove it from that repo.


-----  git remote set-url <remote_name> <new_url_here>

    It can set a new url for the current repository, useful when we change the name of the repository on Github for example, as Github also change the url for this.



-----  git update-index --assume-unchanged <file>

   To temporarily ignore changes in a certain file.

-----  git update-index --no-assume-unchanged <file>

   when you want to track changes again, after they were ignored by assume-unchanged.
