Temporary ignore any changes done to a file in git

When you are working with a project that uses git, and for some reason you need to temporary modify one of the files being managed by git, and you don’t want to bother adding it to the .gitignore config file, one trick that I found was to use the following command

git update-index --assume-unchanged [path/to/file] 

here’s an example of how to actually use it

vulcansmithy@auth-service ~ %> git update-index --assume-unchanged  app/controller/susers_controller.rb

And once you’re good and wanted to revert back to the previous behavior, just use the command below to have git monitor again any changes for the file you specified

git update-index --no-assume-unchanged [path/tofile]

Here’s an actual example of how the above command could be used

vulcansmithy@auth-service ~ %>  git update-index --no-assume-unchanged app/controller/susers_controller.rb
