It solves the ping problem, but doesn't solve "executing another program WITHOUT stoping mine".

This ping thing came into my mind, because where I'm living now I have a BAD ISDN connection that needs to be controlled, so I started opening a window and ping perlmonks -t and just look at it.

After, as a good programmer, I saw so many data passing in the screen and the only thing that I could think about was "ANALYSE!!!!!", so I changed the ping -t into a log file, and started to make a little program that got a little bit bigger, and bigger, and finally, I wanted to put all toghether, and then... the rest you know...

So my main question is not how to ping and log, or how to ping and analyse, is how to execute something else without worying about it after started...

I got a lot of answers that worked below like as for example system "open ping -t perlmonks.org >ping.log".

That one worked perfeclty for what I needed, like that I can open a text editor, I can open a Browser, and in windows, I can say the file that I want to open, or the site (in the case of the browser)...
