Shell program

ruby-talk

Hi, rubyists

I'm using system() to execute a shell program under Windows. I wonder
how I can get the result of the external program as a string, since
the system() returns either true or false. I also try to use the Dos
pipeline to save the result to a file, but it doesn't work like this:
system(" program.exe >result.txt"). I can't find anything to explain
why in ruby document. Anyone can help me a bit?

Thanks,

Sky

string = `program.exe`

(See also: IO.popen for another way.)

Hope this helps,

Thanks, Bill.

The yet another ruby shortcut works.
