Hi list!

In an effort to write my scripts in a posix conform way, I try to use
dash instead of bash. One issue I don't understand:

Why does 'echo \\\\' behave different for bash and dash?

It's a bit confusing that one cannot echo two \\ to another file.

15:46:25-johannes@e13-v21:~$ dash
$ echo \\
\
$ echo \\\\
\

15:46:25-johannes@e13-v21:~$ bash
ech15:46:29-johannes@e13-v21:~$ echo \\\\
\\
15:46:32-johannes@e13-v21:~$ echo \\
\

Thanks for clarifications 8-)

Johannes
