Turtle

Depends on 14 packages(full list with versions):

async, base, clock, directory, foldl, managed, process, system-fileio, system-filepath, temporary, text, time, transformers, unix

turtle is a reimplementation of the Unix command line environment in Haskell so that you can use Haskell as both a shell and a scripting language.

Features include:

Batteries included: Command an extended suite of predefined utilities
Interoperability: You can still run external shell commands
Portability: Works on Windows, OS X, and Linux
Exception safety: Safely acquire and release resources
Streaming: Transform or fold command output in constant space
Patterns: Use typed regular expressions that can parse structured values
Formatting: Type-safe printf-style text formatting
Modern: Supports text and system-filepath

turtle is designed to be beginner-friendly, but as a result lacks certain features, like tracing commands. If you feel comfortable using turtle then you should also check out the Shelly library which provides similar functionality.
