UNIX Gem 3: How to display, segreggate file types:

We have several types of files in a directory (txt,pdf,.pl,.c etc) and we want UNIX to seggregate the file based on their types. How can we achieve this. UNIX has a command file. If we want to display the file type for txt file, just type in
>file filename.txt

If we want to display types for entire files:
file *

If we want to display set of files:

file file1 file 2 file 3

sample output:

file *
