Usage: ag [FILE-TYPE] [OPTIONS] PATTERN [PATH]

  Recursively search for PATTERN in PATH.
  Like grep or ack, but faster.

Example:
  ag -i foo /bar/

     --[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 PATTERN              Print filenames matching PATTERN
  -l --files-with-matches Only print filenames that contain matches
                          (don't print the matching lines)

                          Only print filenames 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)
