Ignore Changes To A Tracked File
July 24, 2015 ยท View on GitHub
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.
