rg is a line-oriented search tool that recursively searches the current directory for a regex pattern, respecting .gitignore by default and outperforming grep/ack/ag on large trees.
Include Ignored Files
By default rg skips files matched by .gitignore, .ignore, and hidden files. --no-ignore disables that filtering.
rg --no-ignore ...Search Only Files of a Certain Type
-t restricts the search to a known file type (e.g. py, js, md). List all supported types with rg --type-list.
rg -t <type> ...Sort by Date
--sort orders results instead of the default (arbitrary/parallel) traversal — useful when you want the most recently touched matches first.
rg --sort modified ...Cheatsheet
rg <pattern> # basic recursive search
rg --no-ignore <pattern> # include gitignored/hidden files
rg -t <type> <pattern> # restrict to a file type
rg --type-list # list available -t types
rg --sort modified <pattern> # sort results by modification time
