sh

Conveniently call external processes from Haskell.

Description

This library makes it convenient to run external processes in your Haskell program.

It offers a single quasi quoter sh to run external processes.

The program's exit code, standard output and standard error can be obtained by parameterizing its output type to ExitCode, (ExitCode, String), (ExitCode, String, String), String, (String, String), respectively. Instead of String, you may chose ByteString or Text, in both lazy and strict variants, as outputs.

Arguments passed to sh are automatically passed to the process in a type-safe way, and appropriately quoted.
