There is a performance edge case where ripgrep doesn't do well where another tool does do well.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.The best tool for this job is good old grep. While ripgrep works on Windows, macOS and Linux, it is not ubiquitous and it does not conform to any standard such as POSIX. You need a portable and ubiquitous tool.This includes searching for results spanning across multiple lines, and opt-in support for PCRE2, which provides look-around and backreference support.Īt this point, the primary reasons not to use ripgrep probably consist of one or more of the following: Why shouldn't I use ripgrep?ĭespite 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. In other words, use ripgrep if you like speed, filtering by default, fewer bugs and Unicode support. ripgrep supports arbitrary input preprocessing filters which could be PDF text extraction, less supported decompression, decrypting, automatic encoding detection and so on.ripgrep supports searching files compressed in a common format (brotli, bzip2, gzip, lz4, lzma, xz, or zstandard) with the -z/-search-zip flag.Other text encodings must be specifically specified with the -E/-encoding flag.) (Some support for automatically detecting UTF-16 is provided. ripgrep supports searching files in text encodings other than UTF-8, such as UTF-16, latin-1, GBK, EUC-JP, Shift_JIS and more.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.gitignore, whereas there are many bugs related to that functionality in other code search tools claiming to provide the same functionality. ripgrep also implements full support for. It also ignores hidden and binary files by default. Like other tools specialized to code search, ripgrep defaults to recursive directory search and won't search files ignored by your.(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. 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. Ripgrep is a line-oriented search tool that recursively searches the current directory for a regex pattern.
