Initializing GIT

Configuration

1. Name,

1

git config --global user.name "Your Name" 

2. Email,

1

git config --global user.email "email@example.com" 

📜 “….” - words in this note mean variable. You have to change ‘em!

Initialization

1. Initialize on a empty directory,

1

git init 

2. Clone from a GitHub/ similar repository,

1

 git clone "repo-user/repo-name"

3. Clone with all sub-modules,

1

git clone --recurse-submodules user/name          

📜 -j8 can be used to boost performance!

4. For an already cloned repository,

1

git submodule update --init --recursive 

Working with GIT

Commit

1. Check status

1

git status 

2. Add a (file|folder) | Work → Stage

1

git add "file|folder"

📜 file = file | folder = folder/

3. Add everything (except files in the .gitignore )

1

git add --all 

or,

1

git add . 

4. Git commit, | Stage → Commit

1

git commit -m "message" 

5. Git commit with tracked file changes,

1

git commit -am "message" 

📜 git add . will track untracked files (not ignored) but git add -u won’t!

Reset

1. reset staged changes | Stage → Work

1

git reset "file|folder"

📜 or, try git reset . to reset everything or, git reset --hard, which may fix errors regarding git pull!

2. To remove files that are listed in the .gitignore but still on the repository,

1

git rm -r --cached .

Then a commit should do the trick for you.

Restore

1. restore one file with

1

git restore file/folder            

2. restore everything with,

1

git restore . 

Logging

1

git log -p  path/to/file_or_directory  

3. Show an overview of which file(s) changed in each commit:

1

git log --stat 

4. Show a graph of commits in the current branch using only the first line of each commit message:

1

git log --oneline --graph 

5. Show a graph of all commits, tags and branches in the entire repository:

1

git log --oneline --decorate --all --graph 

6. Show only commits whose messages include a given string (case-insensitively):

1

git log -i --grep  search_string  

7. Show the last N commits from a certain author:

1

git log -n  number  --author= author

Large file

1. Install git-lfs first. Available on most of official repository of various Linux distributions.
