We have a repository on GitHub that has only two files:
1: Hello World.txt
2: README.md
If you are on a secure or restricted network, you might get a message like this "Could not resolve host: github.com":
(base) C:\Users\ashish\Desktop\Workspace\GitHub>git clone https://github.com/ashishjain1547/my-first-repo.git
Cloning into 'my-first-repo'...
fatal: unable to access 'https://github.com/ashishjain1547/my-first-repo.git/': Could not resolve host: github.com
To fix this, get on an unrestricted network:
(base) C:\Users\ashish\Desktop\Workspace\GitHub>git clone https://github.com/ashishjain1547/my-first-repo.git
Cloning into 'my-first-repo'...

# TO GET CODE FROM A BRANCH:
FIRST CLONE THE MASTER BRANCH AND THEN IF SUPPOSE THE BRANCH YOU WANT TO CHECKOUT IS "dev", THEN TYPE:
$ git checkout -b dev
TO DIRECTLY CLONE A GIT BRANCH:
git clone -b branch remote_repo
Example:
git clone -b my-branch git@github.com:user/myproject.git
With Git 1.7.10 and later, add --single-branch to prevent fetching of all branches. Example, with OpenCV 2.4 branch:
git clone -b opencv-2.4 --single-branch https://github.com/Itseez/opencv.git

IF YOU ARE FACING ISSUE WITH ACCESS ON WINDOWS AFTER CHANGING YOUR CREDENTIALS ON GITHUB, DO THE FOLLOWING:
Go to: Control Panel -> User Accounts -> Credential Manager ->
Choose account for GitHub, proceeding to "Edit Generic Credential"
And set the password that you had set on GitHub.
================================================
TO VIEW WHAT IS YOUR USERNAME CONFIGURED FOR GIT LOGS:
C:\Users\ashish\Desktop\workspace>git config --list
user.name=ashishjain1547
user.email=ashishjain1547@gmail.com
You can also see your Git username in the Git configuration file in your HOME directory on Unix systems, i.e., this file:
~/.gitconfig
OR on Windows PC, at this location: "C:\Users\ashish", you will find the file ".gitconfig" that you can open in editors like Notepad++. You can change the name and email here.
It has contents like:
[filter "lfs"]
clean = git-lfs clean -- %f
smudge = git-lfs smudge -- %f
process = git-lfs filter-process
required = true
[user]

HEAD is now at 10f5fae technology, guest interviews
Suppose I add following lines in the file "Index of Lessons in Technology.html":
HREF = "https://survival8.blogspot.com/p/install-and-set-up-kubectl-on-rhel.html"
TEXT = Install and Set Up kubectl on RHEL
Then on doing "git reset", both of these lines will be removed from the file.
Note: "git reset" does not delete any newly created files that have not been "added and committed" yet.

A scenario when we have a changed file and a newly added file in the local filesystem:
(base) D:\workspace\VisualStudioCode>git pull
Already up to date.
According to "git pull", the local filesystem is "Already up to date" but "git status" will tell you about the changes.
(base) D:\workspace\VisualStudioCode>git status
On branch master
Your branch is up to date with 'origin/master'.
Changes not staged for commit:
(use "git add [file]..." to update what will be committed)
(use "git checkout -- [file]..." to discard changes in working directory)
modified: Personal Postings Index.html
Untracked files:
(use "git add [file]..." to include in what will be committed)

ADDING COLLABORATORS TO A PRIVATE REPOSITORY ON GITHUB
You can add upto 3 collabotors to a repository with the free GitHub account (as of Jan 2020).
The image given below shows how you can add a collaborator from the 'Settings' of a repo.
Once you have added a collaborator, the collaborator will be notified of this addition through mail in account linked with GitHub.
================================================
IF YOUR REPOSITORY CONTAINS WORK THAT YOU DO NOT HAVE LOCALLY, YOU WILL NOT BE ABLE TO PUSH YOUR CHANGES.
But you will still be able to commit as 'commit' is done offline.
E:\Workspace\GitHub\omocron>git commit -m "fixes in code"
[master c5ddab7] fixes in code 20180401
38 files changed, 2610 insertions(+), 50 deletions(-)
E:\Workspace\GitHub\omocron>git push
To https://github.com/ashishjain1547/omocron.git
! [rejected] master -> master (fetch first)
error: failed to push some refs to 'https://github.com/ashishjain1547/omocron.git'
hint: Updates were rejected because the remote contains work that you do not have locally. This is usually caused by another repository pushing to the same ref. You may want to first integrate the remote changes (e.g., 'git pull ...') before pushing again.
See the 'Note about fast-forwards' in 'git push --help' for details.
================================================
IF GIT IS NOT ABLE TO RECOGNIZE THE USER ON THE SYSTEM, IT WILL PROMPT YOU FOR YOUR LOGIN DETAILS:
(base) ashish@ashish-vBox:~/Desktop/VSCode$ git commit -m "bits"
*** 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 'ashish@ashish-vBox.(none)')
