in thread How can I run a piece of code asyncronously in Perl?

t won't work... Thread would be terminated, I suppose.

Why "suppose"? Did you try it?

C:\test>perl -Mthreads -E"async{ qx{perl -E\"sleep 5; die q[Now I'm do +ne];\"} }->detach; select'','','',0.1; die 'I\'m done'" I'm done at -e line 1. C:\test>Now I'm done at -e line 1.

So long as you give the thread chance to start the command running, it will complete even if the thread dies.

Ie. "t1.pl runs completely independently of t2.pl".

It's probably not how I would do it; but then 'it' -- as you've defined it so far -- is so completely pointless, I probably wouldn't do it at all.

But if I did, on Windows I'd probably use system 1, 't1.pl arg1 arg2 arg3';


With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

[erix]: that should be "to an already-too-late- project" I think
[ambrus]: oh yes, we have a pretty good example of that when they reorganized the grill place in the restaurant nearby.
[ambrus]: it now has two more people working there, and they're serving slower and more expensive.
[ambrus]: It used to be just a master cook who takes the order and puts the meat and eggs on the open grill plate table, and an assistant who removes them to a plate, adds the side dish, and gives the plate to the people in the queue, plus a cashier.
[ambrus]: Now it has five people instead of three, some sort of call number ticket system where people wait a lot for their food to get ready (it's the same kinds of grilled meat and fish on the same equipment, it won't actually fry slower),
[ambrus]: it's slow as hell, and the food costs significantly more.
[ambrus]: We no longer eat there.
LanX Everybody quotes it, some people read it, and a few people go by it
[ambrus]: LanX: why would I read it? isn't it a book for managers? I don't want to be a manager.
[ambrus]: I don't quote it either.
