- Recursively search the current directory for a regular expression:

`rg {{regular_expression}}`

- Search for regular expressions recursively in the current directory, including hidden files and files listed in `.gitignore`:

`rg --no-ignore --hidden {{regular_expression}}`

- Search for a regular expression only in a subset of directories:

`rg {{regular_expression}} {{set_of_subdirs}}`

- Search for a regular expression in files matching a glob (e.g. `README.*`):

`rg {{regular_expression}} --glob {{glob}}`

- Search for filenames that match a regular expression:

`rg --files | rg {{regular_expression}}`

- Only list matched files (useful when piping to other commands):

`rg --files-with-matches {{regular_expression}}`

- Show lines that do not match the given regular expression:

`rg --invert-match {{regular_expression}}`

- Search a literal string pattern:

`rg --fixed-strings -- {{string}}`
