  -c --count              Only print the number of matches in each file.
                          (This often differs from the number of matching lines)

     --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

                          (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)
