in reply to Best practice for sychronous output handling using open3()?

with only skimming over the code, i wonder why you have three variables assigned to the same thing? 
my $cmdin=gensym;
my $cmdout=gensym;
my $cmderr=gensym;

Why not just $cmdstuff = gensym?

That said, it seems like this would be a job for something that's probably been written already. I know for sure there are a lot of cron scripts out there...have you looked on CPAN?

meh.

    gensym (in Symbol) returns a ref to a new glob every time it's called. 

    my $cmdin=gensym;
my $cmdout=gensym;
my $cmderr=gensym;
open3($cmdin, $cmdout, $cmderr, $cmd);

    is like 

    my $cmdin=gensym;
my $cmdout=gensym;
my $cmderr=gensym;
open3(\*IN, \*OUT, \*ERR, $cmd);

    without the risk of conflicting names.
