Git Tag

annotated tag
git tag -a v1.5_initial_setup -m 'initial setup'
git tag -a v1.5_initial_setup

lightweight tag
git tag    v1.5_initial_setup

By default git sort order is ascending, for descending order we need to add - sign before the value of --sort parameter

git tag    --sort=taggerdate
git tag -l --sort=taggerdate
 
git tag -l --format='%(taggerdate) %(refname)'
git tag -l --format='%(taggerdate) %(refname)'    --sort=taggerdate

# ascending order
git tag -l --format='%(taggerdate)%09%(refname)'  --sort=taggerdate
git tag -l --format='%(creatordate)%09%(refname)' --sort=creatordate

# descending order
git tag -l --format='%(taggerdate)%09%(refname)'  --sort=-taggerdate
git tag -l --format='%(creatordate)%09%(refname)' --sort=-creatordate

git tag --format='%(creatordate:short)%09%(refname:strip=2)'
git tag --format='%(creatordate:short)%09%(refname:strip=2)' --sort=creatordate
 
git tag --format='%(taggerdate:short)%09%(refname:strip=2)'

Git Branch

create and checkout a new branch
git checkout -b new_branch_name base_branch_name
git checkout -b new_branch_name

renaming and delete branch
git branch -m old_branch_name new_branch_name
git branch -D branch_to_delete_without_merge_status

git branch -d branch_to_delete
git push   -d origin branch_to_delete
git push origin --delete branch_to_delete

renaming branch name
git checkout develop;\
git checkout -b new-dev-branch old-dev-branch;\
git push origin -d old-dev-branch;\
git push origin new-dev-branch

Git Rebase

git checkout <user-branch>
git pull --rebase origin <source-branch>

user branches merge into official branch
─────────────────────────────────────────
merge : user-branch » develop|master
merge : user-branch » staging|uat|production

official branches rebase into user branch
──────────────────────────────────────────
rebase: user-branch « develop|master
rebase: user-branch « staging|uat|production

official branches merge into official branch
─────────────────────────────────────────────
merge : develop » uat » production » master
merge : staging » uat » production » master

Git Commit

delete latest commit
git reset --hard HEAD~1

rollback to the commit id
git reset --hard <sha1-commit-id>

delete commit from remote branch
git push origin HEAD --force

delete commit from local branch
git checkout <your-branch>
git fetch --all && git reset --hard origin/<your-branch>

merge commit from another branch
git cherry-pick <commit>

Git Reflog

 restore commit
 git reflog
 git reset --hard <sha value>

Git Amend Commit

git commit --amend -C HEAD
git push origin HEAD --force
# git push origin <working-branch> --force

Git Merge Commits

Let say there is a new feature needed to develop yourself. During the time of feature creation you have created git checkout -b your_private_branch branch from any others branch like staging or develop. During the time of your development, let say you have added 50 commits for your own tracking. Now you needs to delete 49 commits and have to append your commit with the first commit. After that you need to update your central repository.

Merge Commits Into Single:
Step: 1 git checkout <your_private_branch> git status git log Step: 2 git reset --soft <hash_of_first_commit> git status git log	Step: 3 git commit --amend -m '<comment_about_feature>' git status git log Step: 4 (final) git push origin HEAD --force git status git log
Clean Dirty Branch & Start Again: For safety purpose you should check status and log to ensure your are not doing any wrong. Always be careful before git push origin HEAD --force. Before git push origin HEAD --force please keep backup of your branch into any other locations to avoid any kind of disaster & fast recovery git pull origin your_private_branch.
git stash git stash clear git checkout <any_other_branch>	git branch -D <your_private_branch> git branch -d <your_private_branch> git checkout <your_private_branch>

Git Copy Changes

diff changes:
git diff > ~/Documents/ThinkPad_L14Gen3/my-diff-changes.txt

scp legion:~/Documents/ThinkPad_L14Gen3/my-diff-changes.txt ~/Documents/ThinkPad_L14Gen3/
git apply  ~/Documents/ThinkPad_L14Gen3/my-diff-changes.txt

tracked changes only:
git stash save my-tracked-changes
git stash show -p > ~/Documents/ThinkPad_L14Gen3/my-tracked-changes.txt
git stash pop

scp legion:~/Documents/ThinkPad_L14Gen3/my-tracked-changes.txt ~/Documents/ThinkPad_L14Gen3/
git apply  ~/Documents/ThinkPad_L14Gen3/my-tracked-changes.txt

include untracked changes:
git stash save --include-untracked my-untracked-changes
git stash show -p > ~/Documents/ThinkPad_L14Gen3/my-untracked-changes.txt
git stash pop

scp legion:~/Documents/ThinkPad_L14Gen3/my-untracked-changes.txt ~/Documents/ThinkPad_L14Gen3/
git apply  ~/Documents/ThinkPad_L14Gen3/my-untracked-changes.txt

Git Warning

Pulling without specifying how to reconcile divergent branches is discouraged. You can squelch this message by running one of the following commands sometime before your next pull:

Local/Project Wise git config pull.rebase false git config pull.rebase true git config pull.ff only

Global/Workstation/User Wise git config --global pull.rebase false git config --global pull.rebase true git config --global pull.ff only

Strategy merge (default) rebase (custom ) fast-forward only

delete and recreate
git branch -d staging
git branch -D staging

debug ssh connection
ssh -v  [email protected]

ssh -vT [email protected]

git merge develop
git fetch origin staging
git checkout -b staging origin/staging

git config --global init.defaultBranch master

git stashing

rebase vs merge
git rebase master #all the updated commits of master will be available in the feature branch
git merge --squash feature #all the feature commits replaced by a new commit in the master
git commit -m 'feature merged with master branch'

git checkout uat
git pull --rebase origin staging
