WHAT IS GIT?? Git is free and open source software for distributed version control: tracking changes in any set of files, usually used for coordinating work among programmers collaboratively developing source code during software development. Git means that a local clone of the project is a complete version control repository. These fully functional local repositories make it easy to work offline or remotely.

Git Basic Git clone is a command for downloading existing source code from a remote repository (like Github, for example). In other words, Git clone basically makes an identical copy of the latest version of a project in a repository and saves it to your computer.

GIT BASIC COMMANDS Git clone git clone is primarily used to point to an existing repo and make a clone or copy of that repo at in a new directory,

GIT BASIC COMMANDS Git branch The git branch command lets you create, list, rename, and delete branches

GIT BASIC COMMANDS Creating a new branch commit and push: git branch <branch-name> git status git add README.md git add --all git commit -m "Editing the README to try out git add/commit"

GIT BASIC COMMANDS Short status flags are: ?? - Untracked files A - Files added to stage M - Modified files D - Deleted files R - Renamed C - Copied U - Updated but unmerged F - Force Push.  Other many short flags Short status flags are:

GIT BASIC COMMANDS Creating a new branch commit and push: git commit git push -u <remote> <branch-name>

GIT BASIC COMMANDS Viewing branches: git branch or git branch --list

GIT BASIC COMMANDS Deleting a branch: git branch -d <branch-name>

GIT BASIC COMMANDS Git checkout git checkout <name-of-your-branch>

GIT BASIC COMMANDS Git Pull git pull <remote>

GIT BASIC COMMANDS Git revert A safer way that we can undo our commits is by using git revert. git revert 3321844

GIT BASIC COMMANDS Git merge First you should switch to the dev branch: git checkout dev Before merging, you should update your local dev branch: git fetch

GIT ADVANCE COMMANDS git stash This Git command temporarily stores your modified files. You can work in stashed with the following Git command. git stash Usage And you can view all of your stashes with the following command git stash list And if you need a apply a stash to a branch, simply use apply git stash apply

GIT ADVANCE COMMANDS git rebase Git rebase similar to the git merge command. It integrates two branches into a single branch with one exception. A git rebase command rewrites the commit history.

GIT ADVANCE COMMANDS git rebase Git rebase similar to the git merge command. It integrates two branches into a single branch with one exception. A git rebase command rewrites the commit history. Usage You should use the Git rebase command when you have multiple private branches to consolidate into a single branch. And it will make the commit history linear. git rebase <base>

GIT ADVANCE COMMANDS git cherry-pick Git cherry-pick is a helpful command. It's a robust command and allows you to pick any commit from any branch and apply it to any other branch. Usage git cherry-pick <commit-hash> Git cherry-pick doesn’t modify the history of a repository; instead, it adds to the history.

GIT ADVANCE COMMANDS git archive Git archive command will combine multiple files into a single file. It's like a zip utility, so it means you can extract the archive files to get individual files. Usage git archive --format zip HEAD > archive-HEAD.zip It will create a zip archive of the current revision.

GIT ADVANCE COMMANDS Rewriting history change with amend Git commit --amend and other methods of rewriting history Changing the Last Commit: git commit --amend git commit --amend -m "an updated commit message" git push -f —> It’s use to this is latest code source branch if this command you can’t use then getting error link merge or rebase.

GIT ADVANCE COMMANDS Git tracks changes git reset --hard git reset --hard <SOME-COMMIT> The “--hard” option is used in order to reset the files of the index (or the staging area) and of the working directory. -- hard which will completely destroy any changes and remove them from the local directory.

GIT ADVANCE COMMANDS Git tracks changes git reset --soft HEAD@{1} which will keep your files, and stage all changes back automatically. git reset --mixed HEAD@{1} which is the default, and keeps all files the same but unstages the changes. This is the most flexible option, but despite the name, it doesn’t modify files. git commit -m "Reverting to the state of the project at f414f31" git push -f —> It’s use to this is latest code source branch if this command you can’t use then getting error link merge or rebase.

WHAT IS GIT DIFF COMMAND? Diff command is used in git to track the difference between the changes made on a file. Diff Command will produce the changes in all the files that are present. For the changes on some specific files only, type the name of the file after the command name. 1) git diff 2) git diff filename

WHAT IS GIT DIFF COMMAND? The first line shows the file names that have been considered as the input in git diff. You can see that they have been marked by a and b along with the two different file state that has been taken as input. This line is not of use. This shows the metadata related to the command and the execution of it on the files. As you must be aware by our discussion in Dot Git folder, this is the object hash value required by Git for internal use. This line defines the symbol, called a legend, to tell you what is used to describe the first file and what is used to describe the second file. As you can see, - is used in front of the first file, and + is used in front of the second file. So whenever diff shows you the changes related to the first file, they will be marked by - and the changes in the second file will be marked by the symbol +. The fourth line shows you symbol @@ and symbols ahead of it. They are called chunks. Chunks in git diff define the change' summary. In our image below the following chunk can be seen @@ -1,2 +1 @@ This means that lines one and two were changed in the first file and line one was changed in the second file. Remember the - and + symbol used in the third point as a symbol to the first and second file respectively. 1. 2. 3. 4. 5.
