An alternative syntax is provided via the -engine (default|pcre2|auto-hybrid) option. PCRE2 support can be enabled with -P/-pcre2 (use PCRE2 always) or -auto-hybrid-regex (use PCRE2 only if needed). Among other things, this makes it possible to use look-around and backreferences in your patterns, which are not supported in ripgrep's default regex engine. ripgrep has optional support for switching its regex engine to use PCRE2.Unlike GNU grep, ripgrep stays fast while supporting Unicode (which is always on). ripgrep supports many features found in grep, such as showing the context of search results, searching multiple patterns, highlighting matches with color and full Unicode support.ripgrep can be taught about new file types with custom matching rules. For example, rg -tpy foo limits your search to Python files and rg -Tjs foo excludes JavaScript files from your search. ripgrep can search specific types of files.Automatic filtering can be disabled with rg -uuu. rgignore files, it won't search hidden files and it won't search binary files. Namely, ripgrep won't search files ignored by your. Like other tools specialized to code search, ripgrep defaults to recursive search and does automatic filtering.(See the FAQ for more details on whether ripgrep can truly replace grep.) It can replace many use cases served by other search tools because it contains most of their features and is generally faster.ugrep times are unaffected by the presence or absence of -n. In the above benchmark, passing the -n flag (for showing line numbers) increases the times to 3.423s for ripgrep and 13.031s for GNU grep. LC_ALL=en_US.UTF-8 egrep -w 'Sherlock \w+' Ugrep -r -n -include='*.c' -include='*.h' -w '+_SUSPEND'Įgrep -r -n -include='*.c' -include='*.h' -w '+_SUSPEND'Īnd finally, a straight-up comparison between ripgrep, ugrep and GNU grep on a single large file cached in memory (~13GB, .gz): Tool The corpus is the same as in the previous benchmark, and the flags passed to each command ensure that they are doing equivalent work: Tool Here's another benchmark on the same corpus as above that disregards gitignore files and searches with a whitelist instead. LC_ALL=en_US.UTF-8 git grep -E -n -w '+_SUSPEND' Ugrep -r -ignore-files -no-hidden -I -w '+_SUSPEND' Please remember that a single benchmark is never enough! See my blog post on ripgrep for a very detailed comparison with more benchmarks and analysis. Timings were collected on a system with an Intel i7-6900K 3.2 GHz. This example searches the entire Linux kernel source tree (after running make defconfig & make -j8) for +_SUSPEND, where all matches must be words. Please see the CHANGELOG for a release history. ripgrep is similar to other popular search tools like The Silver Searcher, ack and grep.ĭual-licensed under MIT or the UNLICENSE. (To disable all automatic filtering by default, use rg -uuu.) ripgrep has first class support on Windows, macOS and Linux, with binary downloads available for every release. By default, ripgrep will respect gitignore rules and automatically skip hidden files/directories and binary files. Try browsing this page with examples.Ripgrep is a line-oriented search tool that recursively searches the current directory for a regex pattern. Honestly, the list of possibilities how you can use it is really endless. Remember the rupa/z script? Fzf integrates with it nicely, so if you run z without arguments you can fuzzy search among your most frequently used directories. While searching for a file, Fzf can give you a nice preview (see the screenshot), you just need to specify the preview command: fzf -preview="bat -color=always" You can now fuzzy search among your commands, then press enter to execute it. Or, you try pressing Ctrl+R (the command that runs the command history in the shell). After you press enter, the selected file will open in Vim. You'll be prompted with a list of files, and you can search among those. While that may not sound too impressive, the fun part begins with the applications. Fzf (fuzzy finder) is a super fast tool written in Go which does just one thing: It takes a list of lines as an input and then let's a user fuzzy search in them for some text.
