Ignore Changes To A Tracked File

Files that should never be tracked are listed in your .gitignore file. But what about if you want to ignore some local changes to a tracked file?

You can tell git to assume the file is unchanged

$ git update-index --assume-unchanged <some-file>

Reversing the process can be done with the --no-assume-unchanged flag.
