As scottn and alister suggested. Just use printf instead.
Code:
printf "Hello,world\a\n"

printf is standardized, whereas Posix echo does not include the -e option.

Thank you very much.This help me a lot.Smilie
And one more thing that puzzle me is when typing the following commands in bash
Code:
echo --version

screen output --version
Code:
echo --help

screen output --help
Code:
echo -h

screen output -h

You seem to have a penchant for non-standard commands. First echo -e, now print!

Code:
# echo $0
-bash

# print test
-bash: print: command not found

Why not just use printf and be done with it? In addition to portability you add flexibility.
