Git

Initial Setup

git config --global user.name "Harry Truman"
git config --global user.email "harry.truman@example.com"
git config --global --list

May need to set up SSH-key authentication for gitlab.

Clone Repository

git clone git@gitlab.com:scottcamacmartin/my_project.git

Upload Existing Code Directory as Gitlab Repository

First, creat a new project on gitlab. Then, on the local dev machine:

git clone git@gitlab.com:scottcamacmartin/my_project.git
cd my_project
# then copy code into new folder my_project
# DELETE ANY SENSITIVE PASSWORDS, ETC
# also set up .gitignore file
git status
git add .
git commit -m "initial commit"
git push -u origin master

Overwrite local from repository

git fetch --all
git reset --hard origin/master

As root on git server:

cd ~git

cd project.git
git init --bare
cd ..
chown -R git.git project.git

As developer on developer PC:

cd project
emacs .gitignore  # include a line with "**/.hg" to exclude .hg content
git init

git commit -m 'Initial commit'
git remote add origin git@irc-git-host:project.git
git push origin master

As another user:

git clone git@irc-git-host:project.git
