A Suggestion On Bash

[donglongchao]

Dear Sir or Madam:   
       I have a wonderful idea about Bash(GNU bash version 3.2.39(1)-release 
(i486-pc-linux-gnu)).   

        When I use tools like 'cat' or some other commands like this,I find it 
hard to specify where the file that I 'cat' begins because the command I typed 
just now was mixed with the file I want to read and they look like the same.  

        So I think if we could add special color such as red or green to the 
command lines we typed before to mark them,just like the different colors on 
different kinds of files and catalogues,it will be much easier for us to tell 
where the file we want to read begins. 

        I am looking forward to your replay.  
        Wish you happy!                                                         
                                                                        Yours
