launch a DOS program from a Perl script?

Can I launch a DOS program from within a Perl script?

____

This is what I need to do:

I have many files like this:
c:\dir\pippo-red.html
c:\dir\paperino-yellow.html
c:\dir\pluto-red.html
c:\dir\gastone-green.html

I have a HTML2TXT.EXE program that converts files from html to txt
(removing the tags etc...).

The syntax of this program is: "HTML2TXT htmlfilename.htm >
txtfilename.txt"

I want to convert all and only the file which path-name match "c:\dir
\*-red.html". The output files must have the suffix "-text" in the
filename and ".txt" as extension.

In a few words the Perl script in this example must execute the
command two times like this:
HTML2TXT c:\dir\pippo-red.html > c:\dir\pippo-red-text.txt
HTML2TXT c:\dir\pluto-red.html > c:\dir\pluto-red-text.txt


Do you know how can I do this?


Thanks in advance for any help

Re: launch a DOS program from a Perl script?

This seems to be the solution:
system "HTML2TXT $_ > ".(/(.*)html/)[0]."txt" for ;

but how can I launch it from command-line?
I tried PERL 'system "HTML2TXT $_ > ".(/(.*)html/)[0]."txt" for dir/*-red.html>;' without success...
sorry for my incompetence..

Well, I am not to argue with you but that is not even valid Perl code:

Bareword found where operator expected at t.pl line 5, near "dir"
(Missing operator before dir?)
Bareword found where operator expected at t.pl line 5, near "*-red"
(Missing operator before red?)
syntax error at t.pl line 5, near "dir"
t.pl had compilation errors.

You may want to fix that first.

It might help if you type in the command correctly when testing.

dir/*-red.html>

is not the same as

Re: launch a DOS program from a Perl script?

The solution was:
perl -e "system qq'HTML2TXT $_ > '.(/(.*)html/)[0].'txt' for red.html>"

Indeed. Copy-and-paste error of the oversized line.
My mistake.

Do you need to use Perl? Use plain old DOS?

for %F in (c:\dir\*-red.html) do HTML2TXT "%F" > "%~dF%~pF%~nF.txt"

execute for /? for information.

Genial!

I'm very happy that there is still someone on this earth that master
DOS/BATCH commands.

Thank you VERY VERY much Len! I'll use your solution!

"for /?" revealed an hidden treasure

BTW are there any active communities/forums/message boards on the web
to discuss DOS/BATCH commands?
