GIT : How to ignore changes in Git

To ignore changes in Git, you can use the following methods:

1. Ignore changes to specific files:
   • Create a file named .gitignore in the root directory of your Git repository (if it doesn’t exist already).
   • Open the .gitignore file and add the names of the files or directories you want to ignore, each on a separate line.
   • Save the .gitignore file.
   • Git will now ignore any changes made to the specified files or directories.
2. Ignore changes to all files matching a pattern:
   • Open the .gitignore file.
   • Add a line with a pattern to match the files you want to ignore. You can use wildcards like * to match multiple characters, and / to match directories.
   • Save the .gitignore file.
   • Git will ignore any files that match the specified pattern.
3. Ignore changes to an already tracked file:
   • If you want to ignore changes to a file that is already being tracked by Git, you can use the git update-index command.
   • Run the following command: git update-index --assume-unchanged <file>
   • This tells Git to treat the file as unchanged, and it will no longer show up in the list of modified files.

It’s important to note that ignoring changes does not remove the files from the Git repository. It only tells Git to disregard any modifications made to those files.
