You can try that, but be warned that shell (Unix) syntax in general and bash syntax in particular is a rather mature affair, result of many shaping forces (esp. compatibility to other shells and backward compatibility considerations). At this point in history it has achieved an exquisite equilibrium and there's a huge body of scripts to cater for. So motivation to change syntax at such a basic level is probably pretty low (and with a reason). If you are embedding longer scripts in your shell, consider using "here documents", which are more flexible wrt. embedded quotes. For one-liners, Thomas' solution works nicely. regards - -- tomás -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAlcx0gwACgkQBcgs9XrR2kb6TACfYgdtxEWKUq63xrKc8E53Gd/b QHoAn0/3IB0YTKnmSKVV6LDx6sFwR97A =KOjh -----END PGP SIGNATURE-----
