![]() PCRE2 support can be enabled with -P/-pcre2 (use PCRE2always) or -auto-hybrid-regex (use PCRE2 only if needed). ripgrep has optional support for switching its regex engine to use PCRE2.Among other things, this makes it possible to use look-around andbackreferences in your patterns, which are not supported in ripgrep's defaultregex engine.Unlike GNU grep, ripgrep stays fast whilesupporting Unicode (which is always on). ripgrep supports many features found in grep, such as showing the contextof search results, searching multiple patterns, highlighting matches withcolor and full Unicode support.ripgrep can be taught aboutnew file types with custom matching rules. ripgrep can search specific types of files.For example, rg -tpy foo limits your search to Python files and rg -Tjsfoo excludes JavaScript files from your search.Automatic filtering can bedisabled with rg -uuu. rgignore files, it won't searchhidden files and it won't search binary files. Namely, ripgrep won't search filesignored by your. Like other tools specialized to code search, ripgrep defaults to recursive search and does automaticfiltering.(See the FAQ for more details on whether ripgrep can trulyreplace grep.) It can replace many use cases served by other search toolsbecause it contains most of their features and is generally faster.ugreptimes 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. | Tool | Command | Line count | Time || - | - | - | - || ripgrep | rg -uuu -tc -n -w '+_SUSPEND' | 388 | 0.096s || ugrep | ugrep -r -n -include='*.c' -include='*.h' -w '+_SUSPEND' | 388 | 0.493s || GNU grep | egrep -r -n -include='*.c' -include='*.h' -w '+_SUSPEND' | 388 | 0.806s |Īnd finally, a straight-up comparison between ripgrep, ugrep and GNU grep on asingle large file cached in memory(~13GB, .gz): The corpus is the same as in theprevious benchmark, and the flags passed to each command ensure that they aredoing equivalent work: Here's another benchmark on the same corpus as above that disregards gitignorefiles and searches with a whitelist instead. Please remember that a single benchmark is never enough! See my blog post on ripgrepfor a very detailed comparison with more benchmarks and analysis. Timings were collected on a system with an Inteli7-6900K 3.2 GHz. This example searches the entire Linux kernel source tree(after running make defconfig & make -j8) for +_SUSPEND, whereall matches must be words. Please see the CHANGELOG for a release history. ripgrep is similar toother popular search tools like The Silver Searcher, ack and grep.ĭual-licensed under MIT or the UNLICENSE. (To disableall automatic filtering by default, use rg -uuu.) ripgrep has first classsupport on Windows, macOS and Linux, with binary downloads available for everyrelease. By default, ripgrep will respect gitignore rulesand automatically skip hidden files/directories and binary files. Ripgrep is a line-oriented search tool that recursively searches the currentdirectory for a regex pattern. ![]() Ripgrep recursively searches directories for a regex pattern while respecting your gitignore
