I’m messing around with Sprout still, and looking onto windows compatability.
win32-open3 0.2.5 is required for sprout, but the latest is win32-open3 0.2.6
The main difference I see in the changelog is:
Fixed RubyForge bug #20455 (closed IO stream)
[by the way, is there anyway to search Rubyforge for a bug by ID?]
So I’m looking to see how many file handles I can open in one (ruby) process on Windows, and seeing it it matches up with the 170 listed in the bug.
Anyway, while I’m investigating that, I found a really cool tool that is essentially lsof for windows. The command line version is “handle” but there’s a cool GUI version called “Process Explorer“.
Just thought I’d share in case anyone else is looking for something like it (most likely meaning “me” at some point in the future.)

Okay, process explorer isn’t exactly the same as handle, it’s got a lot more. Think of it more like a task manager on roids.
On the process explorer page is another nice link, to PSTools.

PSList is like PS for unix, and there’s a bunch more.
PSKill, etc.

Very interesting stuff. Of course I haven’t done that much on Windows (not that I’m a unix guru either, but at least the tools are a bit more publicized — and used to be installed by default on Linux)
Okay, finally found the whole sysinternals suite. Just download this, unzip, and add to your path.

so how exactly does one use Process Explorer to find open files like lsof?
