HSH project 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"
runIO $ "ls -l" -|- wcL
runIO $ ("ls", ["-l", "file with spaces.txt"])
glob "~jgoerzen" >>= cd . head
wcL is a pure Haskell function defined in HSH.ShellEquivs.wcL
· GHC 6.6 or above
The first step is to generate your setup file. To do that, run:
Optionally, to run the unit tests, you'll need to install HUnit. Then:
What's New in This Release:
