Set up your user name + email. +----------------------------------- + + $ git config --global user.name "you" + $ git config --global user.email "you@yourserver.org" + +This will create ~/.gitconfig. + +0x1. Centralized workflow - basic notions +----------------------------------------- + +Git avoids touching the network as much as possible. The few basic +commands that require network access are as shown below. + + * git-clone(1) # clone a repo for the first time + * git-push(1) # push your branch + * git-pull(1) # fetch compressed deltas and merge into current branch + +In git you can have tracked and untracked files. In git you have 3 +types of changes. If you modify a tracked file you have `modified' +the file. When you do `git add <file>' you stage the file. Finally +with `git commit' you commit your change into your local branch. + +Staging is important if you have modified one or many files and you +want to select a subset of those changes to commit. This makes it +easy to break down your patches and organize them as needed. Ideally +each patch is useful on its own and unrelated changes are grouped in +separate patches. For more information look at the -p flag for +git-add(1). + +For more advanced operations you should *always* know what state git +is in. You can query that with git-status(1). If you are in the +middle of a merge and you forgot about it, git-status(1) will remind +you. Use git-status(1) frequently. + +0x2. Centralized git workflow +----------------------------- + +To clone a repo: + + $ git clone you@yourserver.org:myrepo.git + +To update your repo: + + $ git pull + + If you have local changes the fetch/merge will proceed as expected. + You can retain your local changes even if they are not committed. + If you have a merge conflict, resolve it by hand and use git-add(1) + and git-commit(1). The history will continue to be linear in case + of a fast-forward merge. + +To look at the commit history and the contents of each patch: + + $ git log -p + +To commit your changes: + + $ git commit -am 'Initial import' + + This will add all modified/deleted files and commit them locally. + New files are not added. To add new files/directories: + + $ git add <file|dir> + $ git commit -m 'awesome' + +To push your changes to the remote branch: + + $ git push + +To push a specific branch: + + $ git push origin mybranch + +To show a diff between your modified files and the HEAD commit in your branch: + + $ git diff + +To show the staged changes (the changes to be committed upon git-commit(1)): + + $ git diff --cached + +To unstage changes: + + $ git reset <file|dir> + +To remove a tracked file/dir: + + $ git rm -r <file|dir> + + This will also stage the change. You can just git-commit(1) at this point. + +To rename a tracked file/dir: + + $ git mv <src> <dst> + + This will also stage the change. You can just git-commit(1) at this point. + +For a simple workflow you can avoid using the staging area completely. +Just use the -am option for git-commit(1) so you can stage and commit +everything in one step. + +0x3. Set up a server-side bare repo for your project +---------------------------------------------------- + +To create a new repo in your home directory: + + $ cd + $ cp -r /tmp/myproject myrepo + $ cd myrepo + $ git init + Initialized empty Git repository in /home/you/myrepo/.git/ + $ git add * + $ git commit -m 'Initial import' + $ cd + $ # We do not need an unpacked repo, just a bare one + $ # no need to waste disk space + $ git clone --bare myrepo myrepo.git + $ rm -rf myrepo + +Assuming your ssh-keys are in place, you can now clone `myrepo.git' +just by doing: + + $ git clone you@yourserver.org:myrepo.git
