Running a Perl script from another Perl script

[Bob MacBob]

Hi all,

I have two scripts:

1/ parser.pl which parses a text file and stuffs the relevant data into a
mySQL DB - works fine no probs there

2/ importer.pl which I want to run through all the relevant files in a
directory and run them through parser.pl

I've got importer.pl to the stage where it can run through a directory and
select the correct files to be processed, but I'm not sure how to pass each
file over to parser.pl. I also need it to wait until parser.pl has finished
processing a file before it passes it another file to process.

I've read the fantastic Perl Cookbook but sadly it's leaving me more
confused than enlightened on this particular issue. :(

Cheers,

Bob

1) Post to comp.lang.perl. misc instead of this group (comp.lang.perl ).

2a) Use system() for one file at a time.

system './parser.pl',$_ foreach @files;

2b) Use system() for all files at once (assuming that parser.pl is
written to handle multiple arguments in @ARGV).

system './parser.pl,@file s;

You should rewrite parser.pl so that it implements a subroutine (better
still a subroutine inside a package) and pass the name of the file to
be processed as an argument to the subroutine, rather than a
command-line argument, which is what you might be doing now. Make sure
there are no global variables shared between parser.pl and importer.pl.
Then, it should be easy to execute 'do "parser.pl" ' in importer.pl,
which will make the subroutine(s) in parser.pl available to the
statements in importer.pl.

If you can't get that to work, post some sample programs (not the real
ones, unless they are very short), but post them to comp.lang.perl. misc
(being sure to follow the guidelines for that newsgroup), because this
newsgroup is defunct.

Thanks.

Thanks to both Joe and Jim.

I'll give those solutions a go and if I have any more questions, I'll post
on the misc group.

Cheers,

Bob
