Commit and upload

Commit changings by:

git add -A
git commit -m "message for commit"

Push to GitHub by:

git push origin master

Then type in usename and password.

Establish remote connection

git remote add origin https://github.com/Shoreshen/Hello.git

Ignore

To ignore files under git workspace, create ignore file:

touch ./.gitignore

Add entries to ignore:

.vscode-ctags #specific file

/edk2/ #Ignore all files under directory ./edk2

To remove already tracked file, need to reset cache

git rm -r --cached .
git add .
git commit -m"update .gitignore"

Submoduel

If there exists submodule, git will not automatically clone them.

To clone all submodules using the following command:

git submodule update --init --recursive

To add submodule using

git submodule add <URL> <PATH>

To remove submodule:

1. Remove relative entries in ./.gitmodules
2. Stage change git add .gitmodules
3. Remove relative entries in .git/config
4. Run git rm --cached <path/to/submodule>
5. Remove file rm -rf .git/modules/<path/to/submodule>
6. Commit all changes git commit -m "Removed submodule"
7. Delete the now untracked submodule files rm -rf <path/to/submodule>

Command

submodual

Documentation in this link.

To first time recursively (including submoduals of submodual) download submoduals:

git submodule update --init --recursive

To set defualt submodule branch:

git submodule set-branch --branch <branch name> <submodule path>

To execute command for each submodual recursively:

git submodule foreach --recursive '<git command>'

The following command pull the submodules to the latest commit of parent reporsitoy. Not the latest commit of submodule repositories.

git pull --recurse-submodules=yes origin master

e.g.: For commit A_1 of rep A, submodule B is at B_1. If rep B has newer commit B_2 and rep A remains, the command will only pull A_1 for rep A and B_1 for rep B.4 Which is the same commit as of A to submodule B.

Compare

Documentation in this link.

Disable scroll and diff session:

git config --global core.page cat

List all commit IDs:

git log

Compare same file in different commits:

git diff <CommitID> <CommitID> <Path/to/File>

Output to file:

git diff --output=<Path/to/log> <CommitID> <CommitID> <Path/to/File>
