This is HsShellScript, a library which enables you to use Haskell for tasks which are typically done by shell scripts. It requires the Glasgow Haskell Compiler.
More elaborate information can be found on the HsShellScript Homepage.
I've ported HsShellScript to base >= 4.17.0.0 && < 5 (GHC 9.4.4 and up). That's the recommended version (as of 2024-04-02). From what I've learnt, I set the bounds of the version of the base package to ">= 4.17.0.0 && < 5".
Cabal is being used. You can just import the parts of HsShellScript and build your program with cabal. HsShellScript will be downloaded and installed automatically.
The documentation is in the API documentation. There you'll also find some examples.
HsShellScript is released under the terms of the GNU Lesser General Public License (LGPL), version 2.1, or any later version.
