Re: [Haskell-cafe] Trouble with readProcess

I've found my mistake: I was calling readProcess cmd ["-p -t"] instead of readProcess cmd ["-p","-t"] Not sure what are the semantics of quotation in this case, though. And I'm pretty sure my analysis is wrong because of that :) -- Cp On Thu, Aug 11, 2011 at 16:05, Donn Cave wrote:

readProcess cmd [opt1,opt2] seems to execute the following: $ cmd "opt1" "opt2"

That is usually fine, but I'm using an external program that doesn't understand the quotes, so I need to execute instead: $ cmd opt1 opt2

How should I do that?

I think your analysis is wrong.  I don't know what to suggest, though if you follow up you probably should mention what platform you're running on.  Maybe you could devise a simple test program that illustrates the problem?
