# ripgrep
> A fast command-line search tool.
- Recursively search the current directory for a regex pattern:
`rg {{pattern}}`
- Search for pattern including all .gitignored and hidden files:
`rg -uu {{pattern}}`
- Search for a pattern only in a certain filetype (e.g., html, css, etc.):
`rg -t {{filetype}} {{pattern}}`
- Search for a pattern only in a subset of directories:
`rg {{pattern}} {{set_of_subdirs}}`
- Search for a pattern in files matching a glob (e.g., `README.*`):
`rg {{pattern}} -g {{glob}}`

- Only list matched files -- useful when piping to other commands:
`rg --files-with-matches {{pattern}}`

- Show lines that do not match the given pattern:
`rg --invert-match {{pattern}}`
