A Moving branches/tags from one git repository to another 1. Clone existing git repo (source repository) git clone --mirror <source git url> eg git clone --mirror git@github.com:source/source.git 2. got to <folder with name of repo> cd <folder with name of repo> 3. Add remote repository ( destination repository ) git remote add new-origin <destination git url> eg git clone --mirror git@github.com:destination/destination.git 4. Move all changes to destination repository git push new-origin --mirror   B If you only want to move some branches 1. git clone <source git repository url> 2. checkout all branches to be moved to new git. git checkout <branch> 3. verify branches to be moved using output of git branch command git branch 4. add destination repository git remote add new-origin git@github.com:destination/destination.git 5. move all local branches to destination repository git push --all new-origin 6. move all tags to destination repository git push --tags new-origin C Move branch to new git repository and changing remote after doing steps mentioned above to move branch from one git to another , use following command to set new origin in git. git remote rm origin git remote rename new-origin origin Note : If you have already moved some branches and want to move one more branch from source git. Running following command might override destination branche or give error. It is always good to move all branches and tags to new repository and start using new repository.	Moving branches/tags from one git repository to another
You have branch having latest changes “latestBranch” and if you want to override master with latestBranch changes. Use following commands 1. Checkout latestBranch. git checkout latestBranch 2. Merge latestBranch with master with strategy as ours. Current branch changes will be used in case of conflicts. git merge -s ours master 3. Checkout master branch. git checkout master 4. Merge master with latestBranch git merge latestBranch 5. Push master with latest code. git push (git push origin master) you can also use git force push “git push -f origin master”. Please check branch history before running git push	Replace/override Master branch with your latest branch in git
Revert merge request	Find commit id of merge request , it can also be seen from UI  or using grep and git log command eg  git log -200 | grep -B 20 "Merge pull request #12"   Once you have commit id , run following command    git revert -m 1 <commitId>   In case of conflict resolve them manually and add files using "git add "   (fix conflicts and run "git revert --continue")   git push
Revert direct commit with commit Id	git rever <commitID>
Added file by mistake using "git add fileName.txt" and want to remove it before commiting from index	git reset fileName.txt
Revert "git add ." from index	git reset
Set Git config username and email	git config --global user.name "firstName lastname" git config --global user.email "abc@test.com"
Create new git repository	git clone git@git.com:platform/project.git cd "projectFolder" touch README.md git add README.md git commit -m "add README" git push -u origin master
Link existing code to Git repo	cd existing_folder git init git remote add origin git@git.com:platform/project.git git add . git commit -m "Initial commit" git push -u origin master
Link existing git repo to new git repoo	cd existing_repo git remote rename origin old-origin git remote add origin git@git.com:platform/project.git git push -u origin --all git push -u origin --tags
