Git Cheat Sheet

I have been working with Git for few months and even if at the start was kind of difficult to grasp it after switching from SVN.

Here is a list of most used commands :


Cloning the repository
> git clone git://url

>  git config --global user.name “Firstname Lastname”

> git config --global user.email “user@email.com”

> git config --global color.ui true

> git config --global alias.st "status" -  define an alias to git status : > git st

List the configuration

> git config --list - list all the configuration

Setup a project in the root directory

>  git init

Look inside the git file

> tree .git

Add all files to repository

> git add .

Commit files to the repository
> git commit -m “First import”

Commit all changes that have done to the project ( ask for a message)

> git commit -a

Add a single file to the commit (is qued up for commit)
> git add {filename} - add the file
> git rm {filename} - delete the file
> git mv {first_file} {second_file} - rename

See prev change ( DIFF between changes)
git diff {filename} - see the difference between changes

get information about the tracked files , changed or new files  
> git status

See log
> git log
> git log --until=2012-06-14
> git log --since=2012-05-12
> git log --author=”James”
> git log --grep=”Init”
> git log --online

HEAD - last state of the repository , what was last checked out

git show {sha} - show the commit information
git diff {sha} - show a diff from a previous commit
git diff {sha1}..{sha2}  show a diff between 2 commits
git diff {sha1}..{sha2}  {filename} - show a diff between 2 commits on a file

git diff --stat --summary
git log --graph --oneline --decorate --all


- master is the main branch ( ~ trunk in the svn)

Branch listing

> git branch

Create a new branch

>  git branch human => (create the “human” branch )

To switch to the human branch we need to log out from the master branch

> git checkout human ( swich to the human branch )

If I want to get the master changes in the human branch

> git rebase master

Merge human to master

First you want to see the changes

1) git checkout master

2) git diff master .. new_feature - compare 2 branches

3) git merge new_feature - merge the branch with the name new_feature ( I am in the master branch)

To check if the branch is merged you can do a diff between branches git diff master..new_feature

If we want to go back before the merge

4) git reset --hard ORIG_HEAD

If we have conflicts on merge make changes and then commit

> git branch --merged - show which branches are merged

> git branch -m {old_branch_name} {new_branch_name}- rename the branch
> git branch -d {branch_name} -
delete a branch

> git push origin :{branch_name} - delete a remote branch

> git push origin --delete {branch_name} - also deletes a remote branch


When you work on the public server you need to push the commit to live server.

> git push

Donwload the last changes

> git pull

Git Architecture:

2-tree architecture - repository & working copy (svn use)
3-tree architecture - repository , stagging index & working copy (git use)

working copy -> git add file.txt ->  staging index -> git commit file.txt -> repository

Undone changes

- undo changes to the working directory

git checkout {filename}  or
git checkout -- {filename}

- unde changes to the staging directory

git reset HEAD {filename}

- change the commit message or add new change to a file that is already on staging directory
git commit --amend -m “Change the files  already staged”

- changes to the older commits
git checkout {hash} -- {filename}

- revert a commit
git revert {hash}

- rever multiple commits ( move the HEAD pointer)
git reset
-- soft (move the pointer but doesn’t change the staging index or working directory)
-- mixed (default) = move the head pointer to the specified commit and change the staging index but doesn’t change the working directory
-- hard - move the HEAD , change the staging index and working directory

git clean -f   - remove the untracked files



- store changes temporary , only visible for you
git stash save “config changes” -
save the files to stash
git stash list
- show the stash lists with the name of the changes
git stash show stash@{0}
- show the file changes in specified stash (to see more add -p option)
git stash pop {stash_item}
- get and remove changes from stash , if a stash item is not specified get the last one
git stash apply {stash_item} -
get the changes from the stash

git stash drop stash@{0} - delete a stash item
git stash clear - remove all stash items

Ignoring files

/proect_dir/.gitignore - add all the files and directories that will be ignored by git.

Sample file:
# comment
test.txt - ignore file test.txt
*.tmp   - ignore all the files that have the extension .tmp

If you want to ignore specific files you need to alter .gitignore_global file located in the user directory

If you want to track an empty directory , create a empty file .gitkeep in that specific directory
