ติดตั้ง Git
Install Git with Yum
sudo yum install git
Install Git with apt
sudo apt install git
ตรวจสอบการติดตั้ง
git --version
Set Up Git
git config --global user.name "Your Name" git config --global user.email "you@example.com"
Checking Your Settings
git config --list
You can view all of your settings and where they are coming from using:
git config --list --show-origin
Your default branch name
By default Git will create a branch called master when you create a new repository with git init. From Git version 2.28 onwards, you can set a different name for the initial branch.
git config --global init.defaultBranch main
Getting a Git Repository
Initializing a Repository in an Existing Directory
cd /home/user/my_project git init
git add *.c git add LICENSE git commit -m 'Initial project version'
Cloning an Existing Repository
You clone a repository with git clone <url>. For example, if you want to clone the Git linkable library called libgit2, you can do so like this:
git clone https://github.com/libgit2/libgit2
If you want to clone the repository into a directory named something other than libgit2, you can specify the new directory name as an additional argument:
git clone https://github.com/libgit2/libgit2 mylibgit
Recording Changes to the Repository
Checking the Status of Your Files
git status
ถ้าจะให้แสดง diff (staged) ด้วยก็
git status -v
หรือถ้าจะดูสรุปสั้นๆก็
git status -s
$ echo 'My Project' > README
$ git status
On branch master
Your branch is up-to-date with 'origin/master'.
Untracked files:
(use "git add <file>..." to include in what will be committed)
README
nothing added to commit but untracked files present (use "git add" to track)
Tracking New Files
git add README
$ git status
On branch master
Your branch is up-to-date with 'origin/master'.
Changes to be committed:
(use "git restore --staged <file>..." to unstage)
new file: README
Ignoring Files
$ cat .gitignore *.[oa] *~
Viewing Your Staged and Unstaged Changes
To see what you’ve changed but not yet staged, type git diff with no other arguments:
git diff
If you want to see what you’ve staged that will go into your next commit, you can use git diff --staged or git diff --cached.
git diff --staged
หรือ
git status -v
Committing Your Changes
git commit -m "Story 182: fix benchmarks for speed"
