Re: [Haskell-cafe] Call external program and get stdout

dons did a blog post about a "shell monad" which I think does what you ask. http://cgi.cse.unsw.edu.au/~dons/blog/2007/03 very nice, I use it myself. t. 2007/11/22, Maurí­cio :

Hi,

How can I call a program (like, for instance, 'grep text *') and get the standard output? All actions I found (executeFile, system) do not give me the output of the program.

Thanks, Maurício
