 ## Cheat Sheet
 
 > Ripgrep (`rg`) is smart. It's like grep if grep were built for code. It
-> respects `.gitignore` and `.ignore`, has all of the sensible options you
-> want (colors, numbers, etc) turned on by default, is written in Rust, and
-> typically outperforms grep in many use cases.

+### Inverse Search

+Use `-v` to filter out all matches so that only non-matches are left.

+rg 'bar' | rg -v 'foobar'

+### Disable Smart Filtering
+
+By default `rg` respects `.gitignore`, `.ignore`, `.git/info/exclude` and
+ignores many types of hidden files, dot files, etc.

+You can use `-uu` to set all of the `--no-ignore-*` options and others.

+rg -uu 'SECRET='
