There you go. You have "history" enabled in SHELLOPTS, which is a non-POSIX extension, and explains why /bin/sh is not doing what you expected. Your shell scripts are inheriting interactive behavior, and trying to do history expansion when they encounter !. I still hope to find time to getting around and trying to teach bash which options in SHELLOPTS should be ignored when starting a non-interactive session. In the meantime, I would recommend turning history off, or at least changing the history expansion character, if you absolutely must set SHELLOPTS. And if all else fails, and you are still running scripts with history enabled, then according to bash documentation, the only way to bypass the history character is to quote it, but that in double quotes, "\!" preserves the \, so you have to write something like: echo "Hello world"\! - -- Don't work too hard, make some time for fun as well!
