to clone a repository:

git clone my_git_address

Branches

list local branches:

git branch

list remote branches:

git branch --remote

Checkout and track a remote branch:

git checkout --track origin/xyz

Push a local branch to a new remote branch name

git push --set-upstream origin <remotebranchname>

delete local git branch

git branch -d <local name>

delete remote branch

git push origin --delete <remote/branch-name>

Status

Sometimes you want to see what has changed. git status can be used to see which files have changed since the last commit. Otherwise, you can use git diff to more closely inspect file changes line by line

git status

git diff

git diff --color=always <commit hash> | less -r

Pushing

Push a quick commit:

If you created a local branch and need to link it to a remote:

git push --set-upstream origin <localbranchname>

git add *
git commit -m "commit message"
git push

or combined:

git add * && git commit -m "update" && git push

log

git log

use this to find the commit hash for prior commits. you can use this to reset

reset

reset to head

git reset

reset to specific commit

git reset <hash>

reset index to head and reset files

git reset --hard

clean

interactive clean

git clean -i

force the removal of all untracked files

git clean -dxf

restore

git restore <path/to/file>

restore all files of the type .c

git restore '*.c'

Submodules

create

git submodule add <repo_address> <your/local/path>

from here

to pull submodules

git submodule update --init --recursive

git submodule update --recursive --remote

cd into the proper subdirectory ensure you are attached to a branch:

git branch

if not check one out

git checkout [branchname]

feetch all remote tags

git fetch --all --tags

check out tag to a new branch

git checkout tags/<tag> -b <branch>
