If it is not, should it be removed from dash? No, it is not standard POSIX (yet). There has been talk on the Austin Group mailing list of standardizing local (perhaps by the name typeset) for the next revision; the biggest issue is that ksh uses typeset only for statically scoped variables, while bash uses it only for dynamically scoped variables, so a consensus has to be reached among shell writers which scoping rules to standardize. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org [-- Attachment #2: OpenPGP digital signature --] [-- Type: application/pgp-signature, Size: 619 bytes --] ^ permalink raw reply [flat|nested] 2+ messages in thread
