Ripgrep

A faster alternative to grep.
Can also perform search/replace.

ripgrep is restricted to single-lines, and does not support lookahead/lookbehind.
If you need these features checkout universal code grep or silversearcher.

Usage

rg --pretty search | less -Ri  # pipe rg to less
rg -g '*.md' search            # search files matching '*.md' for text 'email'
rg -g '!*/test/*' search       # exclude paths matching */test/* (-g can be used multiple times)
rg -i search                   # case insensitive search
rg -uuu search                 # ignore .gitignore, .ignore, ...

# search files from rg
rg 'search' $(rg -l other_search)

# search files from `find`
find . -type f -path '*/mutations/*.rb' -print0 \
  | xargs -0 rg 'search'

Configuration

.ripgreprc

Any arguments you'd like to always be passed to ripgrep, dump in a ripgreprc.
This is not read automatically, you must point to it with the envvar $RIPGREP_CONFIG_PATH.

example

# ./.ripgreprc
