How to Git- Getting older version of project

In this guide, we are going to learn how to getting older version. Going back in history is very simple. The checkout command can copy any snapshot from the repository to the working directory.

View Previous Versions

To Get the list of changes, use git log command.  You should get output that looks something like this:

      commited the deletion of second.txt

 

It displays the list of all the commits to the repository. By default, with no arguments, git log lists the commits made in that repository in reverse chronological order. A huge number and variety of options to the git log command are available to show you exactly what you’re looking for.

To get online history, use --pretty=oneline option with git log. Example

Getting Older Versions

Getting an older version of the project is very simple. The git checkout command can copy any snapshot from the repository to the working directory.

git checkout updates files in the working tree to match the version in the index or the specified tree. Let’s go back to our older version  “Renamed file commit” which is third in our log. Copy the hash from the corresponding log and paste it at the end of checkout command.

 

Git Checkout
  yp@yp-PC MINGW64 ~/lauyou (master)
  $ git checkout 93ec701<br>Note: checking out '93ec701'.

  You are in 'detached HEAD' state. You can look around, make experimental
  changes and commit them, and you can discard any commits you make in this
  state without impacting any branches by performing another checkout.

  If you want to create a new branch to retain commits you create, you may
  do so (now or later) by using -b with the checkout command again. Example:
   git checkout -b <new-branch-name>

  HEAD is now at 93ec701... Renamed file commited

  yp@yp-PC MINGW64 ~/lauyou ((93ec701...))

 

git checkout command checked out the hash (commit number) version from log list.
