+For very rare situations this git command is very handy. I use this on my
+_dotfiles_ repository on a config file that I don't need to update recent
+changes (like htoprc).
+
+## Ignore an already tracked file
+
+```console
+$ git update-index --assume-unchanged <filename>
+```
+
+## Start tracking again
+
+```console
+$ git update-index --no-assume-unchanged <filename>
+```
