## git-extras
The main `git-extras` command.
Output the current `--version`:
```bash
$ git extras
```
List available commands:
```bash
$ git extras --help
```
Update to the latest `git-extras`:
```bash
$ git extras update
```
## git-gh-pages
Sets up the `gh-pages` branch. (See [GitHub Pages](http://pages.github.com/) documentation.)
## git-[feature|refactor|bug] [finish] <name>
Create the given feature, refactor, or bug branch `name`:
```bash
$ git feature dependencies
```
Afterwards, the same command will check it out:
```bash
$ git checkout master
$ git feature dependencies
```
When finished, we can `feature finish` to merge it into the current branch:
```bash
$ git checkout master
$ git feature finish dependencies
```
All of this works with `feature`, `bug`, or `refactor`.
## git-contrib <author>
Output `author`'s contributions to a project:
```bash
$ git contrib visionmedia
visionmedia (18):
Export STATUS_CODES
Replaced several Array.prototype.slice.call() calls with Array.prototype.unshift.call()
Moved help msg to node-repl
Added multiple arg support for sys.puts(), print(), etc.
Fix stack output on socket error
...
```

## git-effort [file ....]
Displays "effort" statistics, currently just the number of commits per file, showing highlighting where the most activity is. The "active days" column is the total number of days which contributed modifications to this file.
```
node (master): git effort --above 15 {src,lib}/*
```
![git effort](http://f.cl.ly/items/0b0w0S2K1d100e2T1a0D/Screen%20Shot%202012-02-08%20at%206.43.34%20PM.png)
If you wish to ignore files with commits `<=` a value you may use `--above`:
```
$ git effort --above 5
```
By default `git ls-files` is used, however you may pass one or more files to `git-effort(1)`, for example:
```
$ git effort bin/* lib/*
```
## git-repl
GIT read-eval-print-loop:
```bash
$ git repl
git> ls-files
History.md
Makefile
Readme.md
bin/git-changelog
bin/git-count
bin/git-delete-branch
bin/git-delete-tag
bin/git-ignore
bin/git-release
git> quit
```
## git-commits-since [date]
List commits since `date` (defaults to "last week"):
```bash
$ git commits-since
... changes since last week
TJ Holowaychuk - Fixed readme
TJ Holowaychuk - Added git-repl
TJ Holowaychuk - Added git-delete-tag
TJ Holowaychuk - Added git-delete-branch
$ git commits-since yesterday
... changes since yesterday
TJ Holowaychuk - Fixed readme
```
## git-count
Output commit count:
```bash
$ git count
total 1844
```

## git-fork
Fork the given github &lt;repo&gt;. Like clone but forks first.
```Shell
$ git fork https://github.com/LearnBoost/expect.js
```
or just:
```Shell
$ git fork LearnBoost/expect.js
```
Does the following:
- forks the repo (prompts for github username and pass)
- clones the repo into the current directory
- adds the original repo as a remote so can track upstream changes
- all remotes refs use git over ssh
```Shell
$ cd expect.js && git remote -v
origin git@github.com:<user>/expect.js (fetch)
origin git@github.com:<user>/expect.js (push)
upstream git@github.com:LearnBoost/expect.js (fetch)
upstream git@github.com:LearnBoost/expect.js (push)
```
## git-release
Release commit with the given &lt;tag&gt;:
```bash
$ git release 0.1.0
```
Does the following:
- Executes _.git/hooks/pre-release.sh_ (if present)
- Commits changes (to changelog etc) with message "Release &lt;tag&gt;"
- Tags with the given &lt;tag&gt;
- Push the branch / tags
- Executes _.git/hooks/post-release.sh_ (if present)
## git-alias
Define, search and show aliases.
Define a new alias:
```bash
$ git alias last "cat-file commit HEAD"
```
Search for aliases that match a pattern (one argument):
```bash
$ git alias ^la
last = cat-file commit HEAD
```
Show all aliases (no arguments):
```bash
$ git alias
s = status
amend = commit --amend
rank = shortlog -sn --no-merges
whatis = show -s --pretty='tformat:%h (%s, %ad)' --date=short
whois = !sh -c 'git log -i -1 --pretty="format:%an <%ae>
```
## git-ignore [pattern ...]
Too lazy to open up `.gitignore`? Me too!
```bash
$ git ignore build "*.o" "*.log"
... added 'build'
... added '*.o'
... added '*.log'
```
Without any patterns, `git-ignore` displays currently ignored patterns:
```bash
$ git ignore
build
*.o
*.log
```
## git-info
Show information about the repo:
```bash
$ git info
## Remote URLs:
origin git@github.com:sampleAuthor/git-extras.git (fetch)
origin git@github.com:sampleAuthor/git-extras.git (push)
## Remote Branches:
origin/HEAD -> origin/master
origin/myBranch
## Local Branches:
myBranch
* master
## Most Recent Commit:
commit e3952df2c172c6f3eb533d8d0b1a6c77250769a7
Author: Sample Author <sampleAuthor@gmail.com>
Added git-info command.
Type 'git log' for more commits, or 'git show <commit id>' for full commit details.
## Configuration (.git/config):

```
If you wish to omit the config section, you may use `--no-config`:
```bash
$ git info --no-config
```
## git-create-branch &lt;name&gt;
Create local and remote branch `name`:
```bash
$ git create-branch development
```
## git-delete-branch &lt;name&gt;
Delete local and remote branch `name`:
```bash
$ git delete-branch integration
```
## git-delete-submodule &lt;name&gt;
Delete submodule `name`:
```bash
$ git delete-submodule lib/foo
```
## git-delete-tag &lt;name&gt;
Delete local and remote tag `name`:
```bash
$ git delete-tag 0.0.1
```
## git-delete-merged-branches
Deletes branches that are listed in `git branch --merged`.
```bash
$ git delete-merged-branches
Deleted feature/themes (was c029ab3).
Deleted feature/live_preview (was a81b002).
Deleted feature/dashboard (was 923befa).
...
```
## git-fresh-branch &lt;name&gt;
Create empty local branch `name`:
```bash
$ git fresh-branch docs
```
## git-graft &lt;src-branch&gt; [dest-branch]
Merge commits from `src-branch` into `dest-branch`. (`dest-branch` defaults to `master`.)
```bash
$ git graft new_feature dev
$ git graft new_feature
```
## git-squash &lt;src-branch|commit ref&gt; [msg]
Merge commits from `src-branch` into the current branch as a _single_ commit.
Also works if a commit reference from the current branch is provided.
When `[msg]` is given `git-commit(1)` will be invoked with that message. This is
useful when small individual commits within a topic branch are irrelevant and
you want to consider the topic as a single change.
```bash
$ git squash fixed-cursor-styling
$ git squash fixed-cursor-styling "Fixed cursor styling"
$ git squash 95b7c52
$ git squash HEAD~3
$ git squash HEAD~3 "Work on a feature"
```
## git-changelog
Populate a file whose name matches `change|history -i_` with commits
since the previous tag. (If there are no tags, populates commits since the project began.)
Opens the changelog in `$EDITOR` when set.
```bash
$ git changelog --tag 1.5.2 && cat History.md

## git-local-commits

```

it applies to and do a rebase. For example:
```bash

Trying to find a commit the patch applies to...
