ripgrep is a line-oriented search tool that recursively searches your current directory for a regex pattern. By default, ripgrep will respect your .gitignore and automatically skip hidden files/directories and binary files. ripgrep has first class support on Windows, macOS and Linux, with binary downloads available for every release. ripgrep is similar to other popular search tools like The Silver Searcher, ack and grep.

This example searches the entire Linux kernel source tree (after running
make defconfig && make -j8) for
[A-Z]+_SUSPEND, where all matches must be
words. Timings were collected on a system with an Intel i7-6900K 3.2 GHz, and
ripgrep was compiled with SIMD enabled.
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.

Here's another benchmark that disregards gitignore files and searches with a whitelist instead. The corpus is the same as in the previous benchmark, and the flags passed to each command ensure that they are doing equivalent work:
And finally, a straight-up comparison between ripgrep and GNU grep on a single
large file (~9.3GB,
In the above benchmark, passing the
-n flag (for showing line numbers)
increases the times to
2.640s for ripgrep and
10.277s for GNU grep.
- It can replace many use cases served by other search tools because it contains most of their features and is generally faster. (See the FAQ for more details on whether ripgrep can truly replace grep.)
- Like other tools specialized to code search, ripgrep defaults to recursive
directory search and won't search files ignored by your
.rgignorefiles. It also ignores hidden and binary files by default. ripgrep also implements full support for
.gitignore, whereas there are many bugs related to that functionality in other code search tools claiming to provide the same functionality.
- ripgrep can search specific types of files. For example,
rg -tpy foolimits your search to Python files and
- 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. Unlike GNU grep, ripgrep stays fast while supporting Unicode (which is always on).
- ripgrep has optional support for switching its regex engine to use PCRE2.
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. PCRE2 support can be enabled with
-P/--pcre2(use PCRE2 always) or
--auto-hybrid-regex(use PCRE2 only if needed).
- ripgrep supports searching files in text encodings other than UTF-8, such
as UTF-16, latin-1, GBK, EUC-JP, Shift_JIS and more. (Some support for
automatically detecting UTF-16 is provided. Other text encodings must be
specifically specified with the
- ripgrep supports searching files compressed in a common format (brotli,
bzip2, gzip, lz4, lzma, xz, or zstandard) with the
- ripgrep supports arbitrary input preprocessing filters which could be PDF text extraction, less supported decompression, decrypting, automatic encoding detection and so on.
In other words, use ripgrep if you like speed, filtering by default, fewer bugs and Unicode support.
Despite initially not wanting to add every feature under the sun to ripgrep, over time, ripgrep has grown support for most features found in other file searching tools. This includes searching for results spanning across multiple lines, and opt-in support for PCRE2, which provides look-around and backreference support.
At this point, the primary reasons not to use ripgrep probably consist of one or more of the following:
- You need a portable and ubiquitous tool. While ripgrep works on Windows, macOS and Linux, it is not ubiquitous and it does not conform to any standard such as POSIX. The best tool for this job is good old grep.
- There still exists some other feature (or bug) not listed in this README that you rely on that's in another tool that isn't in ripgrep.
- There is a performance edge case where ripgrep doesn't do well where another tool does do well. (Please file a bug report!)
- ripgrep isn't possible to install on your machine or isn't available for your platform. (Please file a bug report!)
Generally, yes. A large number of benchmarks with detailed analysis for each is available on my blog.
Summarizing, ripgrep is fast because:
- It is built on top of
Rust's regex engine.
Rust's regex engine uses finite automata, SIMD and aggressive literal
optimizations to make searching very fast. (PCRE2 support can be opted into
- Rust's regex library maintains performance with full Unicode support by building UTF-8 decoding directly into its deterministic finite automaton engine.
- It supports searching with either memory maps or by searching incrementally with an intermediate buffer. The former is better for single files and the latter is better for large directories. ripgrep chooses the best searching strategy for you automatically.
- Applies your ignore patterns in
.gitignorefiles using a
RegexSet. That means a single file path can be matched against multiple glob patterns simultaneously.
- It uses a lock-free parallel recursive directory iterator, courtesy of
Note that ripgrep has grown a few significant new features recently that are not yet present in Andy's table. This includes, but is not limited to, configuration files, passthru, support for searching compressed files, multiline search and opt-in fancy regex support via PCRE2.
The binary name for ripgrep is
Archives of precompiled binaries for ripgrep are available for Windows, macOS and Linux. Users of platforms not explicitly mentioned below are advised to download one of these archives.
Linux binaries are static executables. Windows binaries are available either as built with MinGW (GNU) or with Microsoft Visual C++ (MSVC). When possible, prefer MSVC over GNU, but you'll need to have the Microsoft VC++ 2015 redistributable installed.

If you're a Debian user (or a user of a Debian derivative like Ubuntu),
then ripgrep can be installed using a binary
.deb file provided in each
$ curl -LO https://github.com/BurntSushi/ripgrep/releases/download/11.0.2/ripgrep_11.0.2_amd64.deb $ sudo dpkg -i ripgrep_11.0.2_amd64.deb
If you run Debian Buster (currently Debian testing) or Debian sid, ripgrep is officially maintained by Debian.
$ sudo apt-get install ripgrep
If you're an Ubuntu Cosmic (18.10) (or newer) user, ripgrep is available using the same packaging as Debian:
$ sudo apt-get install ripgrep
(N.B. Various snaps for ripgrep on Ubuntu are also available, but none of them seem to work right and generate a number of very strange bug reports that I don't know how to fix and don't have the time to fix. Therefore, it is no longer a recommended installation option.)
If you're a FreeBSD user, then you can install ripgrep from the official ports:
# pkg install ripgrep
If you're an OpenBSD user, then you can install ripgrep from the official ports:
$ doas pkg_add ripgrep
If you're a NetBSD user, then you can install ripgrep from pkgsrc:
# pkgin install ripgrep
If you're a Rust programmer, ripgrep can be installed with
- Note that the minimum supported version of Rust for ripgrep is 1.34.0, although ripgrep may work with older versions.
- Note that the binary may be bigger than expected because it contains debug
symbols. This is intentional. To remove debug symbols and therefore reduce
the file size, run
stripon the binary.
$ cargo install ripgrep
ripgrep is written in Rust, so you'll need to grab a Rust installation in order to compile it. ripgrep compiles with Rust 1.34.0 (stable) or newer. In general, ripgrep tracks the latest stable release of the Rust compiler.
To build ripgrep:
$ git clone https://github.com/BurntSushi/ripgrep $ cd ripgrep $ cargo build --release $ ./target/release/rg --version 0.1.3
If you have a Rust nightly compiler and a recent Intel CPU, then you can enable additional optional SIMD acceleration like so:
RUSTFLAGS="-C target-cpu=native" cargo build --release --features 'simd-accel'
simd-accel feature enables SIMD support in certain ripgrep dependencies
(responsible for transcoding). They are not necessary to get SIMD optimizations
for search; those are enabled automatically. Hopefully, some day, the
simd-accel feature will similarly become unnecessary. WARNING: Currently,
enabling this option can increase compilation times dramatically.
Finally, optional PCRE2 support can be built with ripgrep by enabling the
$ cargo build --release --features 'pcre2'
--features 'pcre2 simd-accel' to also include compile time SIMD
optimizations, which will only work with a nightly compiler.)
Enabling the PCRE2 feature works with a stable Rust compiler and will
attempt to automatically find and link with your system's PCRE2 library via
pkg-config. If one doesn't exist, then ripgrep will build PCRE2 from source
using your system's C compiler and then statically link it into the final
executable. Static linking can be forced even when there is an available PCRE2
system library by either building ripgrep with the MUSL target or by setting
ripgrep can be built with the MUSL target on Linux by first installing the MUSL library on your system (consult your friendly neighborhood package manager). Then you just need to add MUSL support to your Rust toolchain and rebuild ripgrep, which yields a fully static executable:
$ rustup target add x86_64-unknown-linux-musl $ cargo build --release --target x86_64-unknown-linux-musl
--features flag from above works as expected. If you want to
build a static executable with MUSL and with PCRE2, then you will need to have
musl-gcc installed, which might be in a separate package from the actual
MUSL library, depending on your Linux distribution.
ripgrep is relatively well-tested, including both unit tests and integration tests. To run the full test suite, use:
$ cargo test --all
from the repository root.
