  • Search for files containing a string or regular expression in the current directory recursively:
    ack "search_pattern"
  • Search for a case-insensitive pattern:
    ack --ignore-case "search_pattern"
  • Search for lines matching a pattern, printing [o]nly the matched text and not the rest of the line:
    ack -o "search_pattern"
  • Limit search to files of a specific type:
    ack --type=ruby "search_pattern"
  • Do not search in files of a specific type:
    ack --type=noruby "search_pattern"
  • Count the total number of matches found:
    ack --count --no-filename "search_pattern"
  • Print the file names and the number of matches for each file only:
    ack --count --files-with-matches "search_pattern"
  • List all the values that can be used with `--type`:
    ack --help-types
