With fresh 9.1 install, bash completion no longer expands $HOME
On my 9.0-based machines, if I typed $HOME[tab] when typing a command in bash, the $HOME would be overwritten by the actual path to my home directory (the value of $HOME) and tab completion would work as expected. After a fresh 9.1 install, this does not work as well. $HOME is still detected by completion, but it is not expanded after pressing tab (this does not matter to me), but also an extra space is inserted after tab. For example, if I have a directory named src under my home directory, and my working directory is an unrelated directory, and I type cd $HOME/sr[tab]: Under 9.0: cd /home/dcaldwell/src/[cursor] Under 9.1: cd $HOME/src [cursor] So under 9.1 I lose the slash and see a space instead, essentially, which renders this not very useful. If I use ~ rather than $HOME, it works correctly under both. Obviously I could probably learn to type ~ rather than $HOME but it would be a hard habit to break after years. :) For bash (and for most software) I am using binary packages from the -release distribution, so my 9.0 machines have 4.1.11 and my 9.1 machines have 4.2.37. I don't know enough about all the moving parts to know where to start tracking this down, so can someone point me in the right direction? (Unless there's an known problem or change I'm missing.) I can't figure out where completion is configured in bash outside the /usr/local/etc/bash_completion.d/ directory, which incidentally on my 9.1 setup contains: $ ls /usr/local/etc/bash_completion.d/ dbus-bash-completion.sh*gdbus-bash-completion.sh* gsettings-bash-completion.sh* Thanks, -- David Caldwell http://www.davidpcaldwell.com/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

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 j...@koitsu.org | | UNIX Systems Administratorhttp://jdc.koitsu.org/ | | Making life hard for others since 1977.
