It's somewhat time consuming to navigate to htdocs, and then a specific folder. Is there a way to change the configuration file to have it open elsewhere? Or would it be possible to write a .sh file to do this?…

Question I'm not a git master, but I have been working with it for some time now, with several different projects. In each project, I always git clone [repository] and from that point, can always git pull, so long as I don't have outstanding changes, of course. Recently, I had to revert to a previous branch, and did so with git checkout 4f82a29. When I was again ready to pull, I found that I had to set my branch back to master.…
