The best way of learning Git is practicing it. While practicing, it is beneficial to monitor the index, the status, the objects database and the working copy in some cases. A set of bash/groovy/ruby scripts are created to monitor and analyze Git internals and collected in this repository.
The scrips in this repository are written in Bash, Groovy and Ruby and execute native Git commands. So in order to run all the scripts, the following applications should already be installed on your machine.
- Git 1.7+
- Groovy 2+
- Ruby 2+
Just clone this repository to a folder (e.g. /usr/local/bin) which is in the list of PATH environment variable.

#### git-config-sampleNAME
git-config-sample - Updates your git configuration with the ones we advice
SYNOPSIS
git-config-sample
DESCRIPTION
git-config-sample updates your git configuration with a set of config commands that we
advice to use without fear. I also includes detailed explanation for each config entry.
USAGE
You can directly call the script and let it update the configuration.
git-config-sample
In order to check whether the configurations are updated or not, you can check
`~/.gitconfig` file.
DISCUSSIONS
The content of this script is gathered after using Git for years with many tweaks.
We also made a good search to learn how git-geeks use on their systems.
NAME
git-find-repos - Finds all existing git repositories
SYNOPSIS
git-find-repos [-h | --help] [-d | --dirty] <path>
DESCRIPTION
git-find-repos is a Bash script that searches .git folders recursively under the given folder
path.
OPTIONS
<path>
Path of a folder to run the recursive search. If it is not provided, th directory that
you are in is used for doing the search.
-d, --dirty
Checks the status of detected git repositories. Whenever it finds a repository having
updates that hasn't been push to upstream (these are the updates not added yet, the
updates added but not committed yet, and the updates committed but not pushed yet), it
marks the repository as dirty. With this option, only the dirty repositories are printed,
not all of them.
-h, --help
Prints usage information for help.
USAGE
Typically you can search for all available git repositories. Do not provide the path if you
want to search in your current directory.
git-find-repos
git-find-repos /path/to/search
In order to run the search just the dirty repositories, use -d option.
git-find-repos -d
git-find-repos -d /path/to/search
git-find-repos --dirty /path/to/search
DISCUSSIONS
We clone git repositories to our machines. We use many different source directories to clone
into. For instance, sometimes we clone repositories to our home folder, sometimes to our
`/usr/local/` folder. From time to time we lose track of what we changed in these
repositories. This script is mainly designed for searching git repositories having local
modifications (i.e. -d option). It can also be used to list all git repositories in your
machine to see the overall picture of what you cloned so far.
It might be not possible to search git repositories in some directories due to missing access
rights. On those directories, this script does not warn you.
NAME
git-generate-changes - Generates random file changes and commits to Git repository
SYNOPSIS
git-generate-changes [-h | --help] [-g | --commit] [(-p | --prefix) <prefix>]
[(-c | --count) <number of files>] [(-e | --extension) <extension>]
DESCRIPTION
git-generate-changes is a Bash script for creating bulk random commits in repository.
OPTIONS
-g, --commit
Commit all newly created files to the repository as one file per commit.
-p, --prefix
The prefix of the filename used in the new files. If not given, "temp" is used.
-c, --count
Number of files to create. If not given, count is set to 1.
-e, --extension
The extension of the filename used in new files. If not given, "txt" is used.
-h, --help
Prints usage information for help.
USAGE
If no parameters are entered, the script creates 1 file with the default prefix and extension.
The file is created in the root of the git repository. The number in filename is randomly
selected between 1 and 100.
$ git-generate-changes
temp27.txt ... created
You can define your own file name convention and decide to commit these files as one file
per file.
$ git-generate-changes -g -p catalina -e log -c 3
catalina84.log ... created, committed
catalina17.log ... created, committed
catalina19.log ... created, committed
If the random file name already exists in the same directory, the script updates it.
$ git-generate-changes -g -p catalina -e log -c 3
catalina63.log ... created, committed
catalina17.log ... modified, committed
catalina19.log ... modified, committed
DISCUSSIONS
This script is mainly used when you need random commits while practicing Git. It speeds up
your exercise if your aim is trying -for instance- merge or rebase, not commit.
NAME
git-wtf - Displays the state of your repository in a readable, easy-to-scan format
SYNOPSIS
git-wtf [branch+] [options]
DESCRIPTION
git-wtf is a Ruby script. It displays the state of your repository in a readable, easy-to-scan
format. It's useful for getting a summary of how a branch relates to a remote server, and for
wrangling many topic branches.
OPTIONS
-l, --long
include author info and date for each commit
-a, --all
show all branches across all remote repos, not just those from origin
-A, --all-commits
show all commits, not just the first 5
-s, --short
don't show commits
-k, --key
show key
-r, --relations
show relation to features / integration branches
--dump-config
print out current configuration and exit
USAGE
git-wtf uses some heuristics to determine which branches are integration branches, and which
are feature branches. (Specifically, it assumes the integration branches are named "master",
"next" and "edge".) If it guesses incorrectly, you will have to create a .git-wtfrc file.
To start building a configuration file, run "git-wtf --dump-config > .git-wtfrc" and edit it.
The config file is a YAML file that specifies the integration branches, any branches to
ignore, and the max number of commits to display when --all-commits isn't used. git-wtf will
look for a .git-wtfrc file starting in the current directory, and recursively up to the root.
IMPORTANT NOTE: all local branches referenced in .git-wtfrc must be prefixed with heads/, e.g.
"heads/master". Remote branches must be of the form remotes/<remote>/<branch>.

NAME
gitanalyzer - Analyzes the index and object database of git repositories
SYNOPSIS
gitanalyzer
DESCRIPTION
gitanalyzer is a Groovy script using native Git commands. It analyzes the index (staging area)
and the object database (i.e. .git/objects directory) and produces a report.
The script checks all the objects in object database, compares them with the entries in index
and detects the obsolete ones. As a result, the script creates a report listing all the blobs,
trees, commits and tags with a mark implying the unreferenced objects.
OPTIONS
-d, --debug
prints debug log information on the report
USAGE
The script should be called in a git repository.
gitanalyzer
The report displays all objects including files, folders, commits and tags as a list. At the
end a summary is displayed.
*** INDEX vs OBJECT DATABASE:
index count : 117597
object count : 117597
obsolete count : 0
*** OBJECT TYPES:
commit : 5315
tree : 89948
blob : 22308
tag : 26
*** TIMINGS:
execution time : 1185894.095 ms (20 min)
DISCUSSIONS
The initial aim of this script was to see the impact of garbage collection on objects. But
then the report extended a little bit to prepare overall picture of the index and the object
database.
The script runs slow for big projects due to analysis per object. We plan to improve the
performance in the coming releases.
NAME
git-practice-platform - Creates a bare repo and multiple users for practicing git
SYNOPSIS
git-practice-platform
[-f | --folder <folder>]
[-r | --repository <repository>]
[-u | --usercount <count>]
DESCRIPTION
git-practice-platform is a Bash script that creates a bare repository for simulating remote
repositories, multiple clients cloning the bare repository simulating a teamwork on the
repository.
OPTIONS
-f | --folder <folder>
The name of the root folder where all users clone the repository in it
-r | --repository <repository>
The name of the repository which is created for testing purposes
-u | --usercount <count>
Number of cloning users. If not defined, 2 users are created by default.
USAGE
In order to create 3 users, the following command can be used.
$ git-practice-platform -u 3 -f practicegit -r uberproject
Root folder >>
Created as /Users/user/practicegit
Bare repository >>
Created under server/uberproject.git
User1 repository >>
Created folder server/uberproject.git
Cloned under clients/user1/uberproject.git
Applied initial git configurations
Created file .gitignore
User2 repository >>
Created folder server/uberproject.git
Cloned under clients/user2/uberproject.git
Applied initial git configurations
Created file .gitignore
User3 repository >>
Created folder server/uberproject.git
Cloned under clients/user3/uberproject.git
Applied initial git configurations
Created file .gitignore
1 bare repository and 3 clients are created. Ready for practicing.
And the following folder structure is created.
practicegit/
|-- clients
| |-- user1
| | `-- uberproject.git
| |-- user2
| | `-- uberproject.git
| `-- user3
| `-- uberproject.git
`-- server
`-- uberproject.git
DISCUSSIONS
The best way of learning git is practicing it. We've been practicing git by creating bare
and cloning repositories on our locals for a long time. This script automatises the whole
create folders process and lets you initialize the practicing platform with one command.
NAME
live-findfiles - Continuously displays the files with their paths as a list under the current
folder
SYNOPSIS
live-findfiles [<path>]
DESCRIPTION
live-findfiles is a Bash script that runs find command on every second and displays the files
with their paths (including hidden files and folders)
USAGE
The script runs `find` command and displays the content as a list. By default, it displays
content of the current directory.
live-findfiles
live-findfiles .
It also displays the content of any given directory continuously.
live-findfiles /home/user/project/logs
live-findfiles ~/data
live-findfiles ../../items
DISCUSSIONS
The script can be used to monitor the contents of folders and visualize the impact of git
commands. We use it to monitor object warehouse (.git/objects folder) while using git
commands (add, commit and gc).
NAME
gitcatfile - Displays the raw content of a git object
SYNOPSIS
gitcatfile [-e <path>]
DESCRIPTION
gitanalyzer is a Groovy script. It inflates git objects and displays the raw content. The
objects could be any files under `.git/objects/` directory.
OPTIONS
-e, --extracts
Extracts the object in the given path
USAGE
A valid git object file should be passed to display the raw content.
$ gitcatfile -e .git/objects/1e/8a2b3dcc1092004df16fd151334a963815f4d5
tree 38\0
100644 readme.txt\0 aba8d507fce75a7b9e7b98f800618695c483608b
DISCUSSIONS
Normally we can also view the content of each object by using `git cat-file -p` command.
However it formats the output and does not let you see the raw content. This script
inflates the file via ZLib inflator and parses the content byte by byte. Then converts it
into human-friendly form.
The following the the output of git cat-file command.
$ git cat-file -p 1e8a2b
100644 blob aba8d507fce75a7b9e7b98f800618695c483608b readme.txt
And the following is the output for the same object by our script.
$ gitcatfile -e .git/objects/1e/8a2b3dcc1092004df16fd151334a963815f4d5
tree 38\0
100644 readme.txt\0 aba8d507fce75a7b9e7b98f800618695c483608b
We see null character as "\0" and 20 byte SHA-1 of referencing objects as hex string. New
lines are added between entries to visualize better.
NAME
live-git-index - Generates random file changes and commits to Git repository
SYNOPSIS
live-git-index [-a]
