Thanks. I'm marking this as a wish-list item. If we are to add a section dedicated to options parsing, it's worth noting related discussion about using two dashes to stop processing ( http://bugs.gnu.org/33942 ), and some similar section in the guile manual: https://www.gnu.org/software/guile/manual/html_node/Command-Line-Format.html regards, - assaf

The same is true for short options: 'touch -rfile' and 'touch -r file' are almost identical, except for 'touch -r~file' and 'touch -r ~file'. So it is NOT a case of long options not being as good as short options. Note that bash defaults to doing ~ expansion after =3D, but that this is = a bash extension and is disabled by default when bash is in POSIX mode. But not even bash can tell that you want tilde expansion if you write the argument of a short option adjacent to the option rather than as a separate argument. So in _that_ regards, if you want to pass as small of an argv[] as possible, the long option form with =3D is BETTER than th= e short option form of concatenation, if you use bash as your shell. Spelling long options with a space instead of =3D is fine for all long options that have a mandatory option, and we try to avoid long options with optional arguments (where you have to use =3D). That said, I agree that having some mention in the manual of the effects of =3D~ having different behaviors depending on the shell would be helpful. Remember, if you want tilde expansion it is best to present that option argument as a standalone argument so that the tilde starts the word; when that is not possible (such as for the less common case of an optional argument to a long option), you can use $HOME/ instead of ~/, or else have to resort to a temporary variable to perform the tilde expansion separately, as in: tmp=3D~user; touch --reference=3D$tmp/.pcmanx/pcmanx /cf/pcmanx_time --=20 Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org --OzdPQvmPud3emNryFaFlUN5TKMo1Uq9e9-- --hKwyTdv9CGAFGGwDSqa47GBu7hMTTp4hf Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEY3OaSlgimHGqKqRv3g5py3orov0FAlw2xc8ACgkQ3g5py3or ov3Gdwf6A+EHnwFfj/MHjfvIgFV32yIurs1sO2eimIqM9+IKFJiPy3BsxUHk8kDK WRW+J0xDELOcU23bK2pRNiXOIFhVyyT8RuOCBnIjdYg/kWUoSvjk+X6l/2mV0AT3 zfcxE+Bb5Bo3PgNp3jq6HaYHfB7XyaT+OaN7ZOdfGHaFpRH0UWfjpx9DL4Fft3LH Vhm8UxCbCUjI/WwaRDazcklkH15Bty5oAfsdKQyMNB+pAqS8XFp/nuPhnjNxt+pD saHv1h0KbpmeHWrXMcQ0FthP6BeqX1A3FF5FUFSCzRY0uP34I4LsxR0fm6cYEspj l8cdYI6V06K2AO2Ugt8trzZzRP0BrA== =Gogu -----END PGP SIGNATURE----- --hKwyTdv9CGAFGGwDSqa47GBu7hMTTp4hf--
