From: "Avi Halachmi (:avih)" <avihpit@xxxxxxxxx> Here-documend is standard, and works in all shells. Both here-string and here-doc add final newline, which is important in this case, because $output is without final newline, but we do want "read" to succeed on the last line as well. 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.
