[Haskell-cafe] Execution of external command

[Bulat Ziganshin]

Hello haskell-cafe,

please help me with selection of proper function to use

i need to run external command with parameter and get its stdout, smth
like this:

output <- system "cmd param"

the code should be compatible with unix and windows, and it should be
possible to execute scripts (so afaiu it should execute command via
cmd/sh). i use ghc 6.6.1 and it will be great if this function will
not require any non-bundled libs and be compatible with later ghc
versions
