Here is a basic outline of how to write Git instructions in the repository!
Tell Git who you are Configure the author name and email address to be used with your commits.
Note that Git strips some characters (for example trailing periods) from user.name.
$ git config --global user.name "Salman Shah"
$ git config --global user.email sbs.191197@gmail.com
Create a new local repository
$ git init
Check out a repository
Create a working copy of a local repository:
$ git clone /path/to/repository
For a remote server, use:
$ git clone username@host:/path/to/repository
Add files
Add one or more files to staging (index):
$ git add <filename>
Add all files to staging area:
$ git add .
Commit
Commit changes to head (but not yet to the remote repository):
$ git commit -m "Commit message"
Commit any files you've added with git add, and also commit any files you've changed since then:
$ git commit -a
Push
Send changes to the master branch of your remote repository:
$ git push origin master
Status List the files you've changed and those you still need to add or commit:
$ git status
Connect to a remote repository
If you haven't connected your local repository to a remote server, add the server to be able to push to it:
$ git remote add origin <server>
List all currently configured remote repositories:
$ git remote -v
Branches
Create a new branch and switch to it:
$ git checkout -b <branchname>
Switch from one branch to another:
$ git checkout <branchname>
List all the branches in your repo, and also tell you what branch you're currently in:
$ git branch
Delete the feature branch:
$ git branch -d <branchname>
Delete branch from GitHub
$ git push origin <branchname> --delete
Push the branch to your remote repository, so others can use it:
$ git push origin <branchname>
Push all branches to your remote repository:
$ git push --all origin
Delete a branch on your remote repository:
$ git push origin :<branchname>
Update from the remote repository Fetch and merge changes on the remote server to your working directory:
$ git pull
To merge a different branch into your active branch:
$ git merge <branchname>
View all the merge conflicts:
View the conflicts against the base file:
Preview changes, before merging:
$ git diff
$ git diff --base <filename>
$ git diff <sourcebranch> <targetbranch>
After you have manually resolved any conflicts, you mark the changed file:
$ git add <filename>
Remotes
Remotes are useful for tracking repositories which are present on multiple Git servers(such as Github, Bitbucket, etc.) You can add multiple remote URLs
$ git remote add upstream <url>
Similarly, you can remove added remotes, such as:
$ git remote remove upstream
Undo local changes
If you mess up, you can replace the changes in your working tree with the last content in head:
Changes already added to the index, as well as new files, will be kept.
$ git checkout -- <filename>
Instead, to drop all your local changes and commits, fetch the latest history from the server and point your local master branch at it, do this:
$ git fetch origin
$ git reset --hard origin/master
