From: "Avi Halachmi (:avih)" <avihpit@yahoo.com>

Here-documend is standard, and works in all shells.

Shells which support here-string:
- bash, zsh, mksh, ksh93, yash (non-posix-mode).

shells which don't, and got fixed:
- ash-derivatives (dash, free/net bsd sh, busybox-ash).
- pdksh, openbsd sh.
- All Schily Bourne shell variants.
