The daemon helper, dh is its name.

It's a small C program that starts any program or shell command as a
daemon, then gets out of the way.

Yes I know there are various others. But this is one I wrote, and I
gave it an Apache license.

If you don't like the name "dh" for whatever reason, you can patch the
Makefile and source to give it whatever name you like. Perhaps "dprime"
(daemon primer), or "dp" for a short name.

Yes I know you can fork,setsid,exec in Perl too. But the daemon helper
covers some bases you might not think of, when throwing your Perl script
together. And a tool that already does the job for you, saves time.

because he doesn't like how i paTROL the group?

but a good question that he is not likely to answer. asking him
questions about his reasoning is taken as a personal insult.

Because it can start a Perl script as a daemon, without any need to
fork,setsid,exec in your perl script. I use it myself, to start Perl
scripts as never ending daemons.

Not every post must answer a question. People like to read news too,
though I understand why control freaks hate news, as it threatens their
territorial domain.

I bet it can start a Haskell or C# or Lisp program, too. Did you post in
the corresponding groups for those languages too?

Not yet.

It's topical for a Perl group, because Perl provides sockets and other
features typically used in daemons. The daemon helper lets you omit the
Perl code required for daemon bootstrapping, and focus more readily on
your application, saving time and work.

I don't think it's relevant to Perl specifically as it does not offer
any features Perl does not have, does not extend or contribute to
existing Perl code, and has no Perl interfaces. It's like posting here
about your new car because it can drive you to work where you could
write Perl code.

You should try to popularize your software but this way you will just
annoy people. Try reddit.com for instance.

How would you know that without using it.

So I can't discuss awk, sed, or shell features, and compare or contrast
them to Perl features, because they don't have "Perl interfaces"?

That's a stretched analogy.

Maybe. But popularity is not my goal. It's a niche tool, not many
people attempt to write daemons of any kind, much less in Perl. I put
it out there for the few who may. It helps me save work and time, and
it can help other people too.

If you're not interested in a thread, or it seems off topic to you, why
not ignore it. Every complaint is another opportunity for me to discuss
it.

Thanks, but it looks too noisy to be helpful.

I believe not.

Some people use newsgroups as a social structure where they hang out and
meet friends. So they expect newcomers to behave like themselves. But
I don't use newsgroups that way. To me they are an information resource
and little more. I'm not interested in your social group's approval.

The complainers are making more noise than my original post. If you
can't ignore me, you have no one but yourselves to blame.

newsgroups _are_ social structure. treat them as such.

How can you be sure.

Well I don't mean to belittle anyone who has few other social outlets,
so let me apologize if my words caused offense. But I just can't get
into the spirit of group think online. I need face to face contact for
that.

For those who want to continue discussing psychology, please change the
subject. By now, we are far more off topic than the daemon helper ever
was.
