Ah, I found that usually ubuntu system use "dash" instead of "bash" for the alias of "sh", and its builtin echo command doesn't accept "-e". So if the first option is "-e", it treats all arguments are output string, including -e. Anyway, still using /bin/echo is the best solution. Thank you, -- Masami Hiramatsu <mhiramat@xxxxxxxxxx>
