Notes

GIT: -

Git is a distributed version-control system for tracking changes in
source code during software development. It is designed for
coordinating work among programmers, but it can be used to track
changes in any set of files. Its goals include speed, data integrity,
and support for distributed, non-linear workflows.
Git was created by Linus Torvalds in 2005 for development of the Linux
kernel, with other kernel developers contributing to its initial
development. Its current maintainer since 2005 is Junio Hamano. As
with most other distributed version control systems, and unlike most
client–server systems, every Git directory on every computer is a fullfledged repository with complete history and full version-tracking
abilities, independent of network access or a central server.
Install git: -
You should be running a server with any Ubuntu 16.04 LTS
release. You will need to log in to SSH via the root user.
First, as always, we should start out by running general OS and
package updates. On Ubuntu we’ll do this by running:
>>
apt-get update
>> apt-get install git-core
>> git --version
Installing GIT - apt-get install git
Telling the GIT to track this folder - git init
Colours – Red colour = Files in working directory
Green colour = Files in staging / cache Area
Status Check – git status (for checking the tracking of files)
Commit Id’s – generally called as SHAW1 number
Git init: -
To track the particular folder and git will only take care about the files
but not folders For checking whether it is installed or not check the
hidden files
>> ls –a (or) ls –al
>> git config –-global user.name “XXnameXX”
>> git config –-global user.email “XXemail IDXX”
>> git add filename (or) .[for adding complete files]
>> git commit –m “message for that task”
>> git commit –am “message for the task”
>> git log - -oneline
>> git show commitid
>> vi .gitignore
*.html
*.jpg
! filename.html
>> “git add –f filename”
>> “git checkout filename”
Git Server:-
Development of the GitHub platform began on October 19, 2007.
Projects on GitHub can be accessed and manipulated using the
standard Git command-line interface and all of the standard Git
commands work with it. GitHub also allows registered and
unregistered users to browse public repositories on the site. Multiple
desktop clients and Git plugins have also been created by GitHub and
other third parties that integrate with the platform.
The site provides social networking-like functions such as feeds,
followers, wikis (using wiki software called Gollum) and a social
network graph to display how developers work on their versions
("forks") of a repository and what fork (and branch within that fork) is
newest.
A user must create an account in order to contribute content to the site,
but public repositories can be browsed and downloaded by anyone.
With a registered user account, users are able to have discussions,
manage repositories, submit contributions to others' repositories, and
review changes to code. GitHub began offering unlimited private
repositories at no cost in January 2019 (limited to three contributors
per project). Previously, only public repositories were free.
Installation :-
>> JAVA 8 version need to be installed
>> Terminal should be updated
>> Should have gitbucket .war should be downloaded
>> IP Address should be Reserved and should fix manually
>>
>> Change to Root user - sudo su –root
>> Install the Vim software – apt-get install vim
apt–get install software –properties –common
>> apt-get update
>> apt-get install default-jre
>> apt-get install default-jdk
>> add-apt-repository – rppa:webupdsteam/java
>> apt-get update
>> apt-get install oracle-java8-installer
>> java --version
>> Download Gitbucket.war
>> Go to the path were the gutbucket.war file was situated
>> Java –jar gutbucket.war
>> java –jar gutbucket.war --port =8018
>> apt – get install git
Using local Git bucket :-
>> mkdir myproject – Create a directory
>> cd myproject – navigate to directory
>> git init – initialize the git
>> touch tarun – create a file in myproject
>> git status
>> git add tarun
>> git commit –m ‘commit message’
>> git log
>> gibucket – sign In – root/root (username & password)
>> Goto system Adminstration – New user – Create user with
credentials – sign out - sign in with newly created user >> New
repository - Create a repository
>> git remote add origin URL
>> git push –u origin master
>> View the file called “.gitbucket” (hidden folder)
>> Give the command “- tree .gitbucket “ to view the files in the
repository
Git Branches:-
Branching, in version control and software configuration management,
is the duplication of an object under version control (such as a source
code file or
a directory tree) so that modifications can occur in parallel along
multiple branches.
Branches are also known as trees, streams or codelines. The
originating branch is sometimes called the parent branch, the
upstream branch (or simply upstream, especially if the branches are
maintained by different organizations or individuals), or the backing
stream. Child branches are branches that have a parent; a branch
without a parent is referred to as the trunk or the mainline.
>> git branch
>> git branch newbranchname
>> git checkout branchtochange
>> git merge branchnametomerge
>> git checkout master
>> git branch –D branchname
>> git push origin --delete branchname
Stash Area:-
>> git add .
>> git stash save filename
>> git stash list – To view the stashed files
Play with data in Stash Area
>> Copy + paste = Take a copy from stash area and use it in normally
git stash apply stashID
>>
>> Cut + paste = Move a file from stash and use it normally git stash
pop stashID
>> Delete = Remove files from stash
Area >> git stash drop stashID
Creating Version tags:-
>> git tag version number = Creating a version tag
>> git tag = Wrapping the files and pushing into version
>> git push –u myproject version number = Pushing into github
>> git tag –d version number = Remove versions locally
git push –u myproject --delete version number = Delete the release
in the git hub
Email Notification
>> Whatever happens in the github will be notified through email
>> Steps to activate email notification
>> Login into Git Hub - myproject – Settings – Notifications – Add -
Email Address
Backup and Restore
>> For taking the backup of the files of the git bucket .It is a hidden folder.
>> ls –a (View hidden files)
>> open the .gitbucket fil
>> we can see the files which were pushed
