FreeBSD:

cd /usr/ports/devel/git/ && make install clean

NetBSD:

cd /usr/pkgsrc/devel/scmgit && make install clean

Correct Git version

For submodule support (used by sysless framework) you need at least version 1.5.3.4. Check your version by

git --version

Links for newer version for various distributions:

Basic commands

Initialize a brand new Git repository

$ cd /home/project
$ git init         # with git older than v1.5, use init-db instead of init
$ git add .
$ git commit

First checkout

$ git clone /home/project
$ git clone username@someserver.org:/path/to/repo.git

MinGW port check out project

git clone ssh://username@someserver.org/path/to/repo.git

Browse repository and history using a graphical interface

$ qgit

To be able to do commits from QGIT, check View->Check working dir

Usefull commands

$ git log
$ git log --stat --color

$ git <whatever> --help
$ man git-<whatever>

Before commit

$ git status
$ git diff [--color]
$ git add <file>
$ git commit [-m "message"]

To commit all modified files without the need of
```
git add
```

$ git commit -a [-m "message"]

Send your commits to the central repository

$ git push

Update from server

$ git pull

Pull from others

$ git pull name@1.2.3.4:/path/to/repo.git

Configuration

Global configureation

$ git config --global user.name "Your Name Comes Here"
$ git config --global user.email you@yourdomain.example.com
$ git config --global color.diff auto
$ git config --global color.status auto
$ git config --global color.status auto

You can change it for individual repositories either without --global or in

== Advanced commands ==

Add, move or remove any files

* git add file
* git mv file
* git rm file

Shows the commits which add or remove any file data matching ''string''

$ git log -Sstring

Show what revision and author last modified each line of a file

$ git blame file

Display changes since the last git-update-index:

$ git diff

Display changes since the last commit:

$ git diff HEAD

List all changesets belonging to a specific file

$ git-whatchanged file

Delete all untracked files

$ git clean

Restore a file from the last revision

$ git checkout /file/you/want/to/restore

Force to restore all modified files

$ git checkout -f

== Branches ==

List all branches

$ git branch

Checkout a desired branch

$ git checkout name_of_branch

Create a new branch and make it current

$ git checkout -b new_branch master

Merge changes from one branch into another. Let us suppose that you do work on branch A and branch B,

and after work on those two branches is complete, you merge the work into mainline branch M.

$ git checkout M	# switch to branch M
$ git pull . A		# merge A into M
$ git pull . B		# merge B into M

Delete a branch

$ git branch -d branch_name

Switch to a commit 76ff365f7799e43883d214d7f66a48c5c595c7d2 from the master branch

Setting up a new project and a new remote git repository

On the remote host

$ mkdir /var/git/project
$ cd /var/git/project
$ git --bare init

On your box

$ mkdir /home/project
$ cd /home/project
$ git init                  # with git older than v1.5, use init-db instead of init
$ git add .
$ git commit -a

Put the following lines to your /home/project/.git/config

[remote "origin"]
       url = username@example.com:/var/git/project
       fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
       remote = origin
       merge = refs/heads/master

Push your project onto the host

$ cd /home/project
$ git push origin master

Test if your project has been pushed to the remote host correctly

$ cd /tmp
$ git clone username@example.com:/var/git/project
