Yes, but if you're not careful you can have some of your scripts break
when Ubuntu or Debian change the default non-interactive shell to dash,
then again I don't think that's even backwards compatible with vanilla
Bourne, let alone bash (echo -e).

My scripts are for my consumption, I'd never dream of foisting my
rubbish on the rest of the world! Sounds like Ubuntu/Debian are doing
something daft if they do indeed change their shell to an uncommon
one. I'm a gentoo user though, not sure what they're doing.

I think Ubuntu have already done it, which is daft, AFAIK Debian are
thinking of switching over, hopefully not until issues with dash are
fixed. As well as the echo -e problem [1] I've also had another problem
I can't remember properly, something to do with IFS.

[1] (starting with bash):
~ $ echo '\tHello'
\tHello
~ $ echo -e '\tHello'
Hello
~ $ dash
$ echo '\tHello'
Hello
$ echo -e '\tHello'
-e Hello
$
