Re: http://lists.freebsd.org/pipermail/freebsd-questions/2013-June/251607.html This has nothing to do with FreeBSD 9.0 vs. 9.1 other than the fact that the package on 9.0 is older than 9.1. Instead, this has everything to do with the difference between bash versions you're using. Remember: packages and ports 99% of the time are third-party software (in this case GNU), and therefore any changes in behaviour between versions are entirely independent of FreeBSD. The feature you like from bash 4.1 was removed in some manner of speaking in bash 4.2. This prompted a user to complain -- please read the thread (not just the post) in full, because you will see there are others who *do not* like this behaviour: http://lists.gnu.org/archive/html/bug-bash/2011-02/msg00274.html In bash 4.2.29 -- which is technically "patch 029 for bash 4.2" -- the feature you desire got moved into a shopt feature called "direxpand", with the default being disabled. Because bash 4.3 is not out yet, you will not find any mention of this in the official bash CHANGES file at this time. Instead, you will find the answer in the official bash42-029 patch itself (read the top): ftp://ftp.gnu.org/gnu/bash/bash-4.2-patches/bash42-029 If you do not like this default, or feel strongly about this whole thing and want to discuss it, the GNU bug-bash mailing list is the place: http://www.gnu.org/software/bash/ To enable direxpand, use "shopt -s direxpand". You can put this command in your ~/.bashrc. -- | Jeremy Chadwick jdc@koitsu.org | | UNIX Systems Administrator http://jdc.koitsu.org/ | | Making life hard for others since 1977. PGP 4BD6C0CB |
