the short answer:
my @logData = `program1 -log $data1 $data1 2>&1`;
but since i don't know how windows (i see that you are using Outlook so i
assume you are running Windows) will handle that, it's probably not very
portable. a slightly better solutions would be:
#!/usr/bin/perl -w
use strict;
use IPC::Open3;
my ($r,$w,$e);
waitpid(open3($w,$r,$e,"ls -l"),0);
print "Get $_" while(<$r>);
__END__
prints:
Get f1.pl
Get f2.pl
Get f3.pl
... etc
at best, you should avoide going to the shell all together.
