searchPath :: [FilePath] -> FilePath -> IO (Maybe FilePath)

Search for a file in the search paths.

Catches PermissionDenied and NoSuchThing and returns Nothing.

isShadowed :: FilePath -> IO (Maybe FilePath)

Check wether a binary is shadowed by another one that comes before it in PATH. Returns the path to said binary, if any.

Check whether the binary is in PATH. This returns only True if the directory containing the binary is part of PATH.

expandFilePath :: [Either FilePath Regex] -> IO [FilePath]

Follows the first match in case of Regex.
