The command below returns a list of information about your git configuration including user name and email:
git config -list With the command below you can configure your user name:
git config --global user.name "your-user-name"This command lets you setup the user email address you'll use in your commits.
git config --global user.email "[email protected]"You can store login credentials in the cache so you don't have to type them in each time. Just use this command:
git config --global credential.helper cacheEverything starts from here. The first step is to initialize a new Git repo locally in your project root. You can do so with the command below:
git initThe command below will add a file to the staging area. Just replace filename_here with the name of the file you want to add to the staging area.
git add filename_hereIf you want to add all files in your project to the staging area, you can use a wildcard . and every file will be added for you.
git add .With the asterisk in the command below, you can add all files starting with 'fil' in the staging area.
git add fil*This command will show the status of the current repository including staged, unstaged, and untracked files.
git statusThis command will open a text editor in the terminal where you can write a full commit message. A commit message is made up of a short summary of changes, an empty line, and a full description of the changes after it.
git commitYou can add a commit message without opening the editor. This command lets you only specify a short summary for your commit message.
git commit -m "your commit message here"You can add and commit tracked files with a single command by using the -a and -m options.
git commit -a -m"your commit message here"This command shows the commit history for the current repository:
git logThis command shows the commit's history including all files and their changes:
git log -pThis command shows a specific commit. Replace commit-id with the id of the commit that you find in the commit log after the word commit.
git show commit-idThis command will cause the Git log to show some statistics about the changes in each commit, including line(s) changed and file names.
git log --statYou can pass a file as a parameter to only see changes on a specific file. git diff shows only unstaged changes by default. We can call diff with the --staged flag to see any staged changes.
git diff
git diff all_checks.py
git diff --stagedThis command opens a prompt and asks if you want to stage changes or not, and includes other options.
git add -pThis command expects a commit message to explain why the file was deleted.
git rm filenameThis command stages the changes, then it expects a commit message.
git mv oldfile newfileCreate a .gitignore file and commit it.git checkout filenameYou can use the -p option flag to specify the changes you want to reset.
git reset HEAD filename
git reset HEAD -pgit commit --amend allows you to modify and add changes to the most recent commit.
git commit --amend!!Note!!: fixing up a local commit with amend is great and you can push it to a shared repository after you've fixed it. But you should avoid amending commits that have already been made public.
git revert will create a new commit that is the opposite of everything in the given commit. We can revert the latest commit by using the head alias like this:
git revert HEADYou can revert an old commit using its commit id. This opens the editor so you can add a commit message.
git revert comit_id_hereBy default, you have one branch, the main branch. With this command, you can create a new branch. Git won't switch to it automatically – you will need to do it manually with the next command.
git branch branch_nameWhen you want to use a different or a newly created branch you can use this command:
git checkout branch_nameYou can view all created branches using the git branch command. It will show a list of all branches and mark the current branch with an asterisk and highlight it in green.
git branchIn a single command, you can create and switch to a new branch right away.
git checkout -b branch_nameWhen you are done working with a branch and have merged it, you can delete it using the command below:
git branch -d branch_nameTo merge the history of the branch you are currently in with the branch_name, you will need to use the command below:
git merge branch_nameWe can use --graph to get the commit log to show as a graph. Also, --oneline will limit commit messages to a single line.
git log --graph --onelineDoes the same as the command above, but for all branches.
git log --graph --oneline --allIf you want to throw a merge away and start over, you can run the following command:
git merge --abort##. How to add a remote repository in Git This command adds a remote repository to your local repository (just replace https://repo_here with your remote repo URL).
git add remote https://repo_hereYou can see all remote repositories for your local repository with this command:
git remote -vJust replace origin with the name of the remote obtained by running the git remote -v command.
git remote show originWhen all your work is ready to be saved on a remote repository, you can push all changes using the command below:
git pushIf other team members are working on your repository, you can retrieve the latest changes made to the remote repository with the command below:
git pullThis command shows the name of all remote branches that Git is tracking for the current repository:
git branch -rThis command will download the changes from a remote repo but will not perform a merge on your local branch (as git pull does that instead).
git fetchCommit after commit, Git builds up a log. You can find out the remote repository log by using this command:
git log origin/mainIf the remote repository has changes you want to merge with your local, then this command will do that for you:
git merge origin/mainThis lets you update the remote without merging any content into the local branches. You can call git merge or git checkout to do the merge.
git remote updateIf you want to push a branch to a remote repository you can use the command below. Just remember to add -u to create the branch upstream:
git push -u origin branch_nameIf you no longer need a remote branch you can remove it using the command below:
git push --delete origin branch_name_hereYou can transfer completed work from one branch to another using git rebase.
git rebase branch_name_hereGit Rebase can get really messy if you don't do it properly. Before using this command I suggest that you re-read the official documentation here
You can run git rebase interactively using the -i flag. It will open the editor and present a set of commands you can use.
git rebase -i master
# p, pick = use commit
# r, reword = use commit, but edit the commit message
# e, edit = use commit, but stop for amending
# s, squash = use commit, but meld into previous commit
# f, fixup = like "squash", but discard this commit's log message
# x, exec = run command (the rest of the line) using shell
# d, drop = remove commitThis command will force a push request. This is usually fine for pull request branches because nobody else should have cloned them. But this isn't something that you want to do with public repos.
git push -fInitialize a new repository on the line. you you need to copy the code and run it on command promt. please change usl and title.
echo echo "# Title name of the repository" >> README.md
git init
git add README.md
git commit -m "first commit"
git branch -M main
git remote add origin https://github.com/username/repository-name.git
git push -u origin mainIf you have and existing repository, run this command
git remote add origin https://github.com/username/repository-name.git
git branch -M main
git push -u origin main
