read output and store in file

[b83503104 at yahoo.com]

Hi,

I'm a beginner, and what I want to accomplish is this:

1. For all files under several folders, do some processing (using an
existing program).  The program will output one line of text for each
file.

2. Store the output of all files in one file.

It would be great if someone can give me a crash start on accomplishing
this.  If you think there is a definitely better tool than Python for
doing this, please tell me so.  I just heard that Python or Perl are
better in these kind of jobs.

Thanks.
