Stashing

Often, when you’ve been working on part of your project, things are in a messy state and you want to switch branches for a 
bit to work on something else. The problem is, you don’t want to do a commit of half-done work just so you can get back to 
this point later. The answer to this issue is the git stash command.

for more reference

git stash

   where you have the changes

git stash list

   to list all stash

git stash apply

  to get back the most recent stashed changes

git stash apply stash@{2}

  to get particular stash to local directory , by default most recent

How to rename branch name in local and remote

1. Rename your local branch.
If you are on the branch you want to rename:
git branch -m new-name

If you are on a different branch:
git branch -m old-name new-name

2. Delete the old-name remote branch and push the new-name local branch. 
git push origin :old-name new-name

3. Reset the upstream branch for the new-name local branch.
Switch to the branch and then:
git push origin -u new-name

git fetch

   You can do a git fetch at any time to update your remote-tracking branches under refs/remotes/<remote>/.

  This operation never changes any of your own local branches under refs/heads, and is safe to do without changing your 
  working copy. I have even heard of people running git fetch periodically in a cron job in the background (although I 
  wouldn't recommend doing this).

A git pull is what you would do to bring a local branch up-to-date with its remote version, while also updating your other 
remote-tracking branches.

git pull

  • git pull = git fetch + git merge

git pull makes sure the files in remote and local are same git fetch will get the changes from remote and place it in another branch origin/branch_name, then we need to merge that local branch

git clone

  • downloads the remote repository files to local

      if you want clone repo to particular folder the you need to use below command 
  git clone [email protected]:whatever folder-name

git diff file_name or git diff commit_id

  • it will show you the changes made in particular file or commit

git status

  • it give status of which file modified , added or deleted

git log

  • it gives commit history of a repo

      if you want only last three commits then you can do git log -3.
  if you want commits in oneline then the command will be git log --oneline
