Useful CommandsPermalink

Most used git commands after cloning a project. Target is to create a new feature branch to be used for development and be used for a pull request.

Create new Feature Branch for developmentPermalink

# First checkout the branch from which a new branch is to be created
git checkout <existing develop branch> # Example : future-develop
git pull  # Optional

## Pull the latest changes from parent branch into child
# must be in the child branch. Resolve any conflicts
git merge parent

#Create your branch (2 in 1 command)
git checkout -b feature/<branch-name>
# Make your changes  and commit the files
git commit -m <file names>
# Add the branch remotely
git push -u origin <branch> # (-u short for --set-upstream option)

Switch commitsPermalink

uncommited changesPermalink

Take uncommitted changes from one branch to another

# With Git 2.23
git switch -c <new-branch>

# The same could be achieved prior to Git 2.23 by
git checkout -b <new-branch>

committed changesPermalink

If, by accident, a commit is made in one feature branch, but it was supposed t be in some other branch

# Find the commit hash
git cherry-pick 0359ca8b 

Remove Accidental Pushes from RemotePermalink

git rm <filename or folder> # removes the file from the repo but also deletes it from the local file system.

# To remove the file from the remote repo and not delete it from the local file system use:
git rm --cached <filename or folder>

# remove from local as well as remote
git rm -r --cached <filename or folder>

# Then commit the changes

Creating fresh RepositoryPermalink

Creating a fresh Project Local

Create a repo on Github and copy the repo name.
1. Create an IntelliJ/ Eclipse Project as a new project and goto that path using command prompt

Execute the following in Command prompt

# Initialize a repository
git init

# Create .gitignore and put data
vim .gitignore

# ************** Add some data and files *********************
#Add the files you have worked upon
git add . #(it will take care of ignore files)

#Commit the changes
git commit -m "my_message"

#Add the remote Repo git (ONLY FIRST TIME)
git remote add <branch name (any)> <http git repo address>
git remote add origin <http git repo address> OR
git remote add github <http git repo address> # instead of origin, github is the remote branch

#Add the remote Repo git
git push -u origin master (master is our local repo, branch name)

Delete a remote branch usingPermalink

git push origin --delete <branchName>
git push origin :old_branch

Delete branch from remote repositoryPermalink

git push origin --delete [branchname]

Delete branch from local repositoryPermalink

git branch -d [branchname]

Rename a branchPermalink

# rename a branch while pointed to any branch:
git branch -m <oldname> <newname>

# If you want to rename the current branch, you can simply do:
git branch -m <newname>

Push local branch to repo.Permalink

 git push --set-upstream origin <Branch name>

StashPermalink

View and Clear StashPermalink

Acts as local clipboard to git

# Clear all the stash in one go
git stash clear

# Find all the stash with index Id
git stash list

# Take the index from the stash list
git stash drop stash@{index}

Stash from one branch and bring it on another

If changes are made accidentally on a branch where its not needed, then stash the changes and then bring back into the other branch

--keep-index allows to stash all changes that were not added to staging area.

It safer to run git stash apply as it does not remove stashed changes instead of git stash pop. Conflicts might also occur.
