Git- my everyday learnings

Remove git init

rm -rf .git

Folder to new repository in Github?

Go to said folder & :

  git init

  git add .
	
  git commit -m "First commit"

Source: Github

Create a new git repository, and don’t add any files in it. No readme nothing, just an empty repo.

  git remote add origin remote
  https://github.com/username/name-of-repository.git
	
  git push origin master

That’s it… type in your credentials.

Creating a new git repo and connecting to local

Create a new repo on Github

Open Terminal

  git clone https://github.com/YOUR-USERNAME/YOUR-REPOSITORY

Add create files you want
And then sync with online repo
```
  git add -A
  git commit -m "first commit"
  git push
```
That’s it… type in your credentials.

.gitignore

Sometimes you might want to add a .gitignore file to ignore certain folders or files:

Create the file in the main folder

touch .gitignore

For ignoring files add *.filetype. For ignoring folders add /ignore-this-folder/ followed by git add, git commit, git push (Source, and this). Check your github repo online to see if the changes are reflected. Mostly not!

So do the following based of of this question: gitignore not working

git rm -rf --cached .
git add .

Changing name of git repository

Source

Change name of repository by going to settings on the repo page
Change the repo link on the local git cloned folder
```
  git remote set-url origin new_url
```

Creating a new branch

Source

git checkout master

git checkout -b new_branch master

git push origin new_branch

Going back to older commit

Source

git revert --no-commit oldercommit..HEAD
git commit -m "reverted to oldercommit"

Accidentally uploading a large file commit

You get the dreaded git error from remote saying you tried to commit a large file. In this particular case I had uploaded a file “core” which is genenrated by linux in case of wierd crashes. No worries. this shit can be removed peacefully.

I followed the instructions here as it was a recent commit and I had not done anything after that:

git rm --cached core
git commit --amend -C HEAD

lazygit "comment"

and done. :)

Git local folder to new repo

Refer here regarding installation and PATs

create repo (make public or private), should not matter (but not tested on private)

git commands

git init
git add -A
git commit "first commit"

git remote set-url origin
https://user1@github.com/user1/myRepo1.git
git push -u origin main

git large files shabang

manage large files but with traditional way how we ork with git.

Installation of git-lfs

https://packagecloud.io/github/git-lfs/install#bash

curl -s
https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh
| sudo bash

Follwed by,

sudo apt install git-lfs

Initialze and check if git lfs is installed:

git lfs install

To track files in a repo:

git lfs track '*.zip'

Push

git add .
git commit -m "git lfs commit"
git push

This will give error:

error: failed to push some refs to 'https....gitrepo'

try removing .git/hooks/pre-push and then it works as per here.

Check out git lfs tracking

Go to .gitattributes or type git lfs track. And git lfs ls-files to see which files are tracked.
