IO.popen

Can any body tell me how to convert "Windows command" IO.popen("start
example.pdf") in to Linux or Unix so that the Linux box will open the
"example.pdf" file application.

regards
Eko

IO.popen("xpdf example.pdf")

Doesn't "start" on Windows function as sort of a dispatcher? It knows what
application goes with the file type? Linux/Unix doesn't have any such thing
built in AFAIK. You need to run the program that displays the pdf file yourself.

KDE has "kfmclient exec URL". Gnome probably has something similar.

Thanks

I don't know so much about "start" on windows. Personally it's quite
dangerous function. I accidently find it.
Because:

something.exe ---rename---> something.pdf ----> C:\start something.pdf
---> will executed as something.exe

Is it possible for ruby to find out what is the pdf reader application
installed in the target Computer

In Linux/UNIX? Generally no, unless you know distribution &
installation specific information.

But do try the program "see". It comes from the same package that
provides /etc/mailcap, and so it should be quite common.

Other than that, allow users to specify their own pdf reader.
