Usage: ag [FILE-TYPE] [OPTIONS] PATTERN [PATH]
Recursively search for PATTERN in PATH.
Like grep or ack, but faster.
Example:
ag -i foo /bar/
Output Options:
--ackmate Print results in AckMate-parseable format
-A --after [LINES] Print lines after match (Default: 2)
-B --before [LINES] Print lines before match (Default: 2)
--[no]break Print newlines between matches in different files
(Enabled by default)
-c --count Only print the number of matches in each file.
(This often differs from the number of matching lines)
--[no]color Print color codes in results (Enabled by default)
--color-line-number Color codes for line numbers (Default: 1;33)
--color-match Color codes for result match numbers (Default: 30;43)
--color-path Color codes for path names (Default: 1;32)
--column Print column numbers in results
--[no]filename Print file names (Enabled unless searching a single file)
-H --[no]heading Print file names before each file's matches
(Enabled by default)
-C --context [LINES] Print lines before and after matches (Default: 2)
--[no]group Same as --[no]break --[no]heading
-g --filename-pattern PATTERN
Print filenames matching PATTERN
-l --files-with-matches Only print filenames that contain matches
(don't print the matching lines)
-L --files-without-matches
Only print filenames that don't contain matches
--print-all-files Print headings for all files searched, even those that
don't contain matches
--[no]numbers Print line numbers. Default is to omit line numbers
when searching streams
-o --only-matching Prints only the matching part of the lines
--print-long-lines Print matches on very long lines (Default: >2k characters)
--passthrough When searching a stream, print all lines even if they
don't match
--silent Suppress all log messages, including errors
--stats Print stats (files scanned, time taken, etc.)
--stats-only Print stats and nothing else.
(Same as --count when searching a single file)
--vimgrep Print results like vim's :vimgrep /pattern/g would
(it reports every match on the line)
-0 --null --print0 Separate filenames with null (for 'xargs -0')
Search Options:
-a --all-types Search all files (doesn't include hidden files
or patterns from ignore files)
-D --debug Ridiculous debugging (probably not useful)
--depth NUM Search up to NUM directories deep (Default: 25)
-f --follow Follow symlinks
-F --fixed-strings Alias for --literal for compatibility with grep
-G --file-search-regex PATTERN Limit search to filenames matching PATTERN
--hidden Search hidden files (obeys .*ignore files)
-i --ignore-case Match case insensitively
--ignore PATTERN Ignore files/directories matching PATTERN
(literal file/directory names also allowed)
--ignore-dir NAME Alias for --ignore for compatibility with ack.
-m --max-count NUM Skip the rest of a file after NUM matches (Default: 10,000)
--one-device Don't follow links to other devices.
-p --path-to-ignore STRING
Use .ignore file at STRING
-Q --literal Don't parse PATTERN as a regular expression
-s --case-sensitive Match case sensitively
-S --smart-case Match case insensitively unless PATTERN contains
uppercase characters (Enabled by default)
--search-binary Search binary files for matches
-t --all-text Search all text files (doesn't include hidden files)
-u --unrestricted Search all files (ignore .ignore, .gitignore, etc.;
searches binary and hidden files as well)
-U --skip-vcs-ignores Ignore VCS ignore files
(.gitignore, .hgignore; still obey .ignore)
-v --invert-match
-w --word-regexp Only match whole words
-W --width NUM Truncate match lines after NUM characters
-z --search-zip Search contents of compressed (e.g., gzip) files
File Types:
The search can be restricted to certain types of files. Example:
ag --html needle
- Searches for 'needle' in files with suffix .htm, .html, .shtml or .xhtml.
For a list of supported file types run:
ag --list-file-types
