HSH is designed to let you mix and match shell expressions with Haskell programs. With HSH, it is possible to easily run shell commands, capture their output or provide their input, and pipe them to/from other shell commands and arbitrary Haskell functions at will.
Here are a few examples to get you started:
run $ "echo /etc/pass*" :: IO String -> "/etc/passwd /etc/passwd-" runIO $ "ls -l" -|- "wc -l" -> 12 runIO $ "ls -l" -|- wcL -> 12 runIO $ ("ls", ["-l", "file with spaces.txt"]) glob "~jgoerzen" >>= cd . head
wcL is a pure Haskell function defined in HSH.ShellEquivs.wcL

Downloads: Source and Binaries
- Source downloads are available from the HSH Hackage page
- The latest development trees are available via the Github project page
- You can find Debian packages from the HSH Debian Page.
- RPMs and packages for many other Linux and BSD distributions are also included with your distribution.
You can always download the source from the Downloads page and attach diffs. But it’s far better, both for you and for me, if you use Git.
