rg man page

rg — recursively search current directory for lines matching a pattern


rg [options] -e PATTERN ... [<path> ...]

rg [options] <pattern> [<path> ...]

rg [options] --files [<path> ...]

rg [options] --type-list

rg [options] --help

rg [options] --version


rg (ripgrep) combines the usability of The Silver Searcher (an ack clone) with the raw speed of grep.

Common Options

-a, --text
Search binary files as if they were text.
-c, --count
Only show count of line matches for each file.
--color WHEN
Whether to use coloring in match. Valid values are never, always or auto. [default: auto]
-e, --regexp PATTERN ...
Use PATTERN to search. This option can be provided multiple times, where all patterns given are searched.
-F, --fixed-strings
Treat the pattern as a literal string instead of a regular expression.
-g, --glob GLOB ...
Include or exclude files for searching that match the given glob. This always overrides any other ignore logic. Multiple glob flags may be used. Globbing rules match .gitignore globs. Precede a glob with a '!' to exclude it.
-h, --help
Show this usage message.
-i, --ignore-case
Case insensitive search.
-n, --line-number
Show line numbers (1-based). This is enabled by default at a tty.
-N, --no-line-number
Suppress line numbers.
-q, --quiet
Do not print anything to stdout. If a match is found in a file, stop searching that file.
-r, --replace ARG
Replace every match with the string given. Capture group indices (e.g., $5) and names (e.g., $foo) are supported.
-t, --type TYPE ...
Only search files matching TYPE. Multiple type flags may be provided. Use the --type-list flag to list all available types.
-T, --type-not TYPE ...
Do not search files matching TYPE. Multiple not-type flags may be provided.
-u, --unrestricted ...
Reduce the level of 'smart' searching. A single -u doesn't respect .gitignore (etc.) files. Two -u flags will search hidden files and directories. Three -u flags will search binary files. -uu is equivalent to grep -r, and -uuu is equivalent to grep -a -r.
-v, --invert-match
Invert matching.
-w, --word-regexp
Only show matches surrounded by word boundaries. This is equivalent to putting \b before and after the search pattern.

Less Common Options

-A, --after-context NUM
Show NUM lines after each match.
-B, --before-context NUM
Show NUM lines before each match.
-C, --context NUM
Show NUM lines before and after each match.
Show column numbers (1 based) in output. This only shows the column numbers for the first match on each line. Note that this doesn't try to account for Unicode. One byte is equal to one column.
--context-separator ARG
The string to use when separating non-continuous context lines. Escape sequences may be used. [default: --]
Show debug messages.
Print each file that would be searched (but don't search).
-l, --files-with-matches
Only show path of each file with matches.
-H, --with-filename
Prefix each match with the file name that contains it. This is the default when more than one file is searched.
Never show the filename for a match. This is the default when one file is searched.
Show the file name above clusters of matches from each file. This is the default mode at a tty.
Don't show any file name heading.
Search hidden directories and files. (Hidden directories and files are skipped by default.)
-L, --follow
Follow symlinks.
Search using memory maps when possible. This is enabled by default when ripgrep thinks it will be faster. (Note that mmap searching doesn't currently support the various context related options.)
Never use memory maps, even when they might be faster.
Don't respect ignore files (.gitignore, .ignore, etc.) This implies --no-ignore-parent.
Don't respect ignore files in parent directories.
Don't respect version control ignore files (e.g., .gitignore). Note that .ignore files will continue to be respected.
Whenever a file name is printed, follow it with a NUL byte. This includes printing filenames before matches, and when printing a list of matching files such as with --count, --files-with-matches and --files.
-p, --pretty
Alias for --color=always --heading -n.
-S, --smart-case
Search case insensitively if the pattern is all lowercase. Search case sensitively otherwise.
-j, --threads ARG
The number of threads to use. Defaults to the number of logical CPUs (capped at 6). [default: 0]
Show the version number of ripgrep and exit.
Show results with every match on its own line, including line numbers and column numbers. (With this option, a line with more than one match of the regex will be printed more than once.)

File Type Management Options

Show all supported file types and their associated globs.
--type-add ARG ...
Add a new glob for a particular file type. Only one glob can be added at a time. Multiple --type-add flags can be provided. Unless --type-clear is used, globs are added to any existing globs inside of ripgrep. Note that this must be passed to every invocation of rg.

Example: --type-add html:*.html

--type-clear TYPE ...
Clear the file type globs previously defined for TYPE. This only clears the default type definitions that are found inside of ripgrep. Note that this must be passed to every invocation of rg.
