08/19/2002 10:37p 4,238 index.html
08/19/2002 10:37p 7,292 ch00_01.htm

Please help,

"help" implies that you have made an attempt and would like assistance
in figuring out why it doesn't meet your specifications.

Please post the code you have written so far, and explain how it does
not function the way you would like it to. That way, we have a chance
of helping you correct your errors.

If you just have no idea where to start, I suggest you begin at
http://learn.perl.org, and read the documentation dealing with opening
files, reading files, splitting lines into separate fields, and
printing to files.
perldoc -f open
perldoc -f readline
perldoc -f split
perldoc -f print

Untested:

perl -le '@ARGV = map /([^ ]+\.htm)$/, <>; print <>' listing.txt

I wonder if the produced file would have <html> </html> all through
it, which would look like a mess?.
