Some Basic Git and Github Commands

Git Common Commands

git init

to initialize git for a specific folder we need to go into the folder and initialize the git so it can monitor the changes in it. It initializes an empty repository

git status

to see that status of our initialized repository. what files we have in our folder. which branch we are on, what is the status of untracked files , what we need to commit etc. give the information of current state of git repository

git add filename or git add .

"git add filename" adds a specific file to a stage. A stage is a step between tracked and untracked files. After we initialize a folder using git init git detects if any files are inside the directory. if we delete them before adding them git can't restore them. but if we add them and commit them then we can restore those files. "git add filename" adds a single file "git add ." add all the files inside our directory which can be risky if we want some files not to be tracked. git add actually adds the untracked files to a stage and once we commit we can track them properly. only adding them makes file recognizeable but not trackable. after commiting the files becomes trackeable.

git commit - m "Message"

to commit any changes to our repo. if we have made some changes to our files and we have added them we can use commit to permanently monitor those changes.

git push -u origin master

to push code to a master branch. by default a master branch is initialized and created but we can create other branches tool.

Git Branch Commands

git checkout -b branchanme or git branch new_branch_name

to create a new branch with a specific branchname. it means to checkout from main/master branch and create a new branch.

git checkout master

git ls-files

git branch or git branch -av

It list all the branches in our repo and also shows on which branch we are in with a * before our branch.

git branch -d branchname

git push origin --delete branchname

after deleting a branch from local repo we can reflect the changes in our remote server(github) by using above commands. this will delete the branch on github too.

git merge branch_name

Git Diff Command
