Process module:System -package:unix -package:Win32 -package:clock -package:cmdargs is:exact

Operations for creating and interacting with sub-processes.
A module adapting the functions from System.Process to work with io-streams.
A running process. The three type parameters provide the type of the standard input, standard output, and standard error streams. To interact with a Process use the functions from the section Interact with a process.
Use OS processes just like native Haskell functions - to generate, transform or consume streams. See Streamly.System.Command module for a higher level wrapper over this module. See also: Streamly.Internal.System.Process for unreleased functions.
