#Git-Reset: Unstaged the file to current commit
git reset HEAD~
or
git reset --hard

Remove the last commit, you can simply run git reset --hard HEAD^ If you are removing multiple commits from the top, you can run git reset --hard HEAD~2 to remove the last two commits. You can increase the number.

If you want to "uncommit" the commits, but keep the changes around for reworking, remove the "--hard": git reset HEAD^

#Git-checkout: Discarding local changes (permanently) to a file
git checkout -- filename
# clear all local change
git checkout .

--Allow apache user to exec a git pull command

#gitBranchSwitch
git checkout develop

#gitNewbranchCreate (-b)
git checkout -b develop

git push --set-upstream origin develop

At first, we need to come to our desire branch where we want to merge. Example checkout to master branch then merge the develop branch to master.

git merge develop

git config core.autocrlf true
