How to filter ack search by files17.06.24

# Example

```

# to find all possible types
```command
ack --help-types 
```

### possible types
```txt  
Usage: ack [OPTION]... PATTERN [FILES OR DIRECTORIES]

The following is the list of filetypes supported by ack.  You can specify a
filetype to include with -t TYPE or --type=TYPE.  You can exclude a
filetype with -T TYPE or --type=noTYPE.

Note that some files may appear in multiple types.  For example, a file
called Rakefile is both Ruby (--type=ruby) and Rakefile (--type=rakefile).
