git commands fundamentals

What I have learned as Git basic commands

• git init
• git log
• git status
• git add 
• git add -u
• git commit -m "message for comming"
• git diff HEAD~1..
• git diff <#hash code>..<#hash code>
• git clean (it is to delete files from system!)
• .gitignore
• git log origin/master
• git branch -r
• git pull origin branch
• git commit -am "commit"  (no need to use "git add" as separate step)
• git tag -a | git tag -s
• git config --global alias.lga "log --graph --oneline --all --decorate"
• git reflog (2nd trash bin - 30days by default only)
• git stash | git stash list | git stash apply | git stash pop | git stash branch new_branch_for_stash(half way work, nor do want to commit, nor want to lose the modification)
• git checkout (go to a branch or fetch latest file version)
• git checkout master ; git merge feature1 (merge feature1 into master branch)
• git diff --cached (compare repo and staging area)
• git rebase (rebase the branches created from, conflicts might occur)
• git cherry-pick (allow one commit and merge into)
• git push origin master:new_branch (push master branch's changes up to origin's new_branch branch, ":new_branch" is optional if the branch name is the same as local branch)
• git push origin  :remote_branch_name (delete remote branch should be done with caution, because other people might be working on top of it)
• git log -p -1 <file or path> or git log -p <file or path>
