Subject: Help on I/O pipe

One process of my analysis program uses an external non-linear optimizer.
That optimizer needs a model file as the argument. The current approach I
employ to accomplish this is to create a model file on disk everytime
running the optimizer. The code is simply like

@model =3D File.open("model.mod", "w")
...
@model.close
result  =3D `optimizer.exe model.mod`

The problem is that I have to repeat running optimizer on different models
many many times during the analysis. I wonder if such heavy writing on a
single file will do any harm to my hard disk. My concern of improving it is
to use I/O pipe to feed the optimizer without the needs to create real mode=
l
files. Can anyone give me some tips or examples on using the shell pipe? Th=
e
rdoc isn't so clear.

Thanks
