I am using Git Bash and am trying a few things like making a 'commit' and 'push' to GitHub.
I want to get out of the current directory C:\user\myUsername\app
and land in the C:\user\myUsername
folder.
What commands do I write in Git Bash?
To change your directory in git-bash to that specific path you can use this command :
cd /c/user/myUsername
basically you have to replace backslash with standard slash, or otherwise if you simply want to go to the parent directory you can use :
cd ..
as stated in comments that you already received on your question ...
