Thanks! I'll give that a try (what I found interesting of using getEnv, though, is that it seems simple to use arbitrary variables I set for ad-hoc needs in .profile, even if it is kind of a kludge).
Best,
R.

Using environment variables to get hostname feels a bit unstable. I personally read /etc/hostname to determine the hostname, like this:
hostname <- fmap trimString (readFile "/etc/hostname")
where `trimString` is:
trimString :: String -> String trimString = f . f where f = reverse . dropWhile isSpace
There's also `hostname` package, which uses proper library functions to determine hostname: https://hackage.haskell.org/package/hostname
