![]() When this flag is used, ripgrep will dynamically choose between supported regex engines depending on the features used in a pattern. ![]() This overrides the -context and -passthru flags. In all cases, the flag specified last takes precedence. Each flag’s documentation notes whether an inverted flag exists. These flags are useful for overriding a ripgrep configuration file on the command line. For example, the -no-ignore flag (listed below) disables ripgrep’s gitignore logic, but the -ignore flag (not listed below) enables it. For example, the -column flag (listed below) enables column numbers in ripgrep’s output, but the -no-column flag (not listed below) disables them. In some cases, those flags are not listed in a first class way below. Note that many options can be disabled via flags. File paths specified explicitly on the command line override glob and ignore rules. To match a pattern beginning with a dash, use the -e/ -regexp option. Positional Arguments PATTERNĪ regular expression used for searching. If you’re using ripgrep with the -pcre2 flag, then please consult or the PCRE2 man pages for documentation on the supported syntax. This makes them very similar to the "extended" (ERE) regular expressions supported by egrep, but with a few additional features like Unicode character classes. To a first approximation, ripgrep uses Perl-like regexes without look-around or backreferences. Ripgrep uses byte-oriented regexes, which has some additional documentation: */regex/bytes/index.html#syntax Ripgrep uses Rust’s regex engine by default, which documents its syntax: */regex/#syntax Tip: to disable all smart filtering and make ripgrep behave a bit more like classical grep, use rg -uuu. To turn off stdin detection explicitly specify the directory to search, e.g. In some environments, stdin may exist when it shouldn’t. Ripgrep will automatically detect if stdin exists and search stdin for a regex pattern, e.g. For more details, see the man page or the README. The file can specify one shell argument per line. Set RIPGREP_CONFIG_PATH to a configuration file. However, if ripgrep is built with PCRE2, then the -pcre2 flag can be used to enable backreferences and look-around. Because of this, features like backreferences and arbitrary look-around are not supported. Ripgrep’s default regex engine uses finite automata and guarantees linear time searching. gitignore and automatically skip hidden files/directories and binary files. ![]() ![]() Ripgrep (rg) recursively searches the current directory for a regex pattern. Search a literal string pattern: rg -fixed-strings - string.Show lines that do not match the given regular expression: rg -invert-match regular_expression.Only list matched files (useful when piping to other commands): rg -files-with-matches regular_expression.Search for filenames that match a regular expression: rg -files | rg regular_expression.README.*): rg regular_expression -glob glob Search for a regular expression in files matching a glob (e.g.Search for a regular expression only in a subset of directories: rg regular_expression set_of_subdirs.gitignore: rg -no-ignore -hidden regular_expression Search for regular expressions recursively in the current directory, including hidden files and files listed in.Recursively search the current directory for a regular expression: rg regular_expression.Recursively search the current directory for lines matching a pattern Examples (TL DR) ![]()
