I will try to keep this post updated with useful tips for git usage.
Currently the content is inspired by the excellent book I read recently Pragmatic Version Control Using Git by Travis Swicegood.

#Pushing project folder to git
Commit names are SHA-1 hashes generated by Git to keep track of a commit.
mkdir mysite cd mysite git init git add file git commit -m "added X"
There are three places in Git where your code can be stored. First, the one you work with directly when editing files is the working tree. Second is the index, which I’ll refer to as the staging area. The staging area is a buffer between your working tree and what is stored in the repository, the third and final area in Git. You can use the staging area to stage only the changes you want to commit to the repository.
git add changed.file git status git commit -m "" git log -1
The command has the -a parameter on it. That tells Git to commit all files that it knows about that have changed
git commit -a
You can use Git’s interactive add mode to select which files or parts of files to stage for a commit. You start it by adding the -i option.
git add -i
git branch RB_1.0 master git checkout BR1
You use git branch to delete the branch by adding the -d parameter before the branch name
git branch -d RB_1.0
Create branch + checkout with single command.
git checkout -b alternate master
Rebasing takes the changes from a branch and replays them on top of another branch
git checkout master git rebase BR1
Calling git diff with no parameters shows you the changes in your working tree that you haven’t staged or committed yet.
View the differences in the staging area and the repository by adding –cached to the call:
git diff --cached
The differences in the working tree (also staged) and your repository
git diff HEAD
Change statistics since tag 1.0
git diff --stat 1.0</pre>
Straight merging - pulls the entire history of one branch inyo another
git merge alternate_branch</pre>
Squashing commits - all the history of one branch compressed into one commit (f.e. doing bugfix)
git merge --squash emailfix
Cherry-picking commits - if we need only selected commit(s) from branch
git cherry-pick 4f3f42b
git log git log 5435dgfd git log --since="5 hours" git log 80fd599c5499055ba799969c6fdc8b09cc734843..HEAD git log --pretty=format:"%h %s" 1.0..HEAD - since particular tag git log --pretty=oneline 1.0.. git log -1 HEAD^^ git log -1 HEAD~3
git blame README git blame -L 1,2 README git blame -L 1,+2 README</pre>
git revert -n HEAD git reset --soft / --hard HEAD^</pre>
git remote add origin git@git:groovy-study.git git push origin master git config --add branch.master.remote origin git config --add branch.master.merge refs/heads/master</pre>
or edit in .git/config
[branch "master"] remote = origin merge = refs/heads/master</pre>
- Tag milestones
- Branch releases
- Use directory-like structure names
