WHAT IS GIT??
Git is free and open source software for
distributed version control tracking changes in
any set of files, usually used for coordinating
work among programmers collaboratively
developing source code during software
development. Git means that a local clone of the
project is a complete version control
repository. These fully functional local
repositories make it easy to work offline or
remotely.

clone basically makes an identical copy of the
latest version of a project in a repository and

WHAT IS GIT DIFF COMMAND?
39
WHAT IS GIT DIFF COMMAND?

• Diff command is used in git to track the
  difference between the changes made on a file.
• Diff Command will produce the changes in all the
  files that are present. For the changes on some
  specific files only, type the name of the file
  after the command name.
• git diff
• git diff filename

WHAT IS GIT DIFF COMMAND?

1. The first line shows the file names that have
   been considered as the input in git diff. You
   can see that they have been marked by a and b
   along with the two different file state that has
   been taken as input.
2. This line is not of use. This shows the metadata
   related to the command and the execution of it
   on the files. As you must be aware by our
   discussion in Dot Git folder, this is the object
   hash value required by Git for internal use.
3. This line defines the symbol, called a legend, to
   tell you what is used to describe the first file
   and what is used to describe the second file. As
   you can see, - is used in front of the first
   file, and is used in front of the second file.
   So whenever diff shows you the changes related to
   the first file, they will be marked by - and the
   changes in the second file will be marked by the
   symbol .
4. The fourth line shows you symbol _at__at_ and symbols
   ahead of it. They are called chunks. Chunks in
   git diff define the change' summary. In our image
   below the following chunk can be seen _at__at_ -1,2 1
   _at__at_
5. This means that lines one and two were changed in
   the first file and line one was changed in the
   second file. Remember the - and symbol used in
   the third point as a symbol to the first and
   second file respectively.
