通过ruby从msinfo32.exe创建报告

Question

I would like to silently save out a report from msinfo32.exe using ruby. How can I do so? I tried the following

system "msinfo32.exe /\report c:/\/\temp/\/\fromruby.txt"
exec 'msinfo32.exe /\report c:/\/\temp/\/\fromruby.txt'
IO.popen("msinfo32.exe /\report c:/\/\temp/\/\fromruby.txt")

and all of these open the application instead of silently creating the report.

Thanks in advance.

system "msinfo32.exe /\report c:/\/\temp/\/\fromruby.txt"

\\r is a carriage return, \\t is a tab character, and \\f is a formfeed. none of those have to be escaped at all in the first place.

so instead of executing a single command:

msinfo32.exe /report c:\temp\fromruby.txt

you're executing all of these separate commands:

msinfo32.exe /
eport c://        temp//
romruby.txt
