Push Changes

⬆️ How to Push Changes to GitHub¶

Pushing transfers commits from your local repository to a remote repository.

1. Clone & Prepare¶

Let's clone the repository:

ubuntu@manikandan:~$ git clone https://github.com/devopspilot2/firstproject.git
Cloning into 'firstproject'...
remote: Enumerating objects: 3, done.
remote: Counting objects: 100% (3/3), done.
remote: Total 3 (delta 0), reused 0 (delta 0), pack-reused 0
Receiving objects: 100% (3/3), done.
ubuntu@manikandan:~$ cd firstproject/
ubuntu@manikandan:~/firstproject$ ll
total 4
-rw-rw-r-- 1 ubuntu ubuntu 14 Jun  2 23:41 README.md

In this firstproject repository we have only README.md file.

2. Make Changes¶

Let's create a new file hello.txt:

ubuntu@manikandan:~/firstproject$ echo "Created for git demo" > hello.txt
ubuntu@manikandan:~/firstproject$ ll
total 8
-rw-rw-r-- 1 ubuntu ubuntu 14 Jun  2 23:41 README.md
-rw-rw-r-- 1 ubuntu ubuntu 21 Jun  2 23:42 hello.txt
ubuntu@manikandan:~/firstproject$ cat hello.txt 
Created for git demo

3. Check Status¶

Run git status to check the status of the file:

ubuntu@manikandan:~/firstproject$ git status
On branch main
Your branch is up to date with 'origin/main'.

Untracked files:
  (use "git add <file>..." to include in what will be committed)
        hello.txt

nothing added to commit but untracked files present (use "git add" to track)

In the untracked files, its showing the newly created file hello.txt.

4. Stage & Commit¶

Run git add to track the file:

ubuntu@manikandan:~/firstproject$ git add hello.txt 
ubuntu@manikandan:~/firstproject$ git status
On branch main
Your branch is up to date with 'origin/main'.

Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
        new file:   hello.txt

Now commit the file:

ubuntu@manikandan:~/firstproject$ git commit -m "Added hello.txt for git demo"
Author identity unknown

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got 'ubuntu@manikandan.(none)')

The command has failed, since the author name and email id is not configured. This is a one-time activity.

Configure Identity:

ubuntu@manikandan:~/firstproject$ git config --global user.email "devopspilot2@gmail.com"
ubuntu@manikandan:~/firstproject$ git config --global user.name "Vignesh Sweekaran"

Verify configuration:

ubuntu@manikandan:~/firstproject$ git config -l --global
user.email=devopspilot2@gmail.com
user.name=Vignesh Sweekaran

Retry Commit:

ubuntu@manikandan:~/firstproject$ git commit -m "Added hello.txt for git demo"
[main d26925d] Added hello.txt for git demo
 1 file changed, 1 insertion(+)
 create mode 100644 hello.txt

5. Push to Remote¶

Run git push origin main. It will ask for username and password.

Note: You must use a Personal Access Token (PAT) as the password.
