[Bash-completion-devel] Bug#781404: Processed: Re: Bug#781404: dd: BASH completion overwrites option prefix

[Peter Cordes]

Programmable completion bugs very often get reported in the wrong
place.  Most users aren't aware of how exactly it happens under the
hood.  Also, some packages do ship custom completions for the commands
they provide.

 In this case, dd completion is dynamically loaded from
/usr/share/bash-completion/completions/dd, a file maintained by
the bash-completion package.

$ complete -p dd
complete -o nospace -F _dd dd


Usually un-reproducible broken-behaviour reports come from people with
old cruft in /etc/bash_completion.d.  Every file in there is sourced
when the main bash-completion script loads.  Old acroread packages
were notable for re-defining bash-completion standard functions in a
way that broke things.

So, David, check everything in /etc/bash_completion.d to make sure
apt thinks it SHOULD be there, or that you put it there yourself.

e.g. on my system
$ dpkg -S /etc/bash_completion.d/* > /dev/null
dpkg-query: no path found matching pattern /etc/bash_completion.d/dput.dpkg-old
dpkg-query: no path found matching pattern /etc/bash_completion.d/git.dpkg-old

found files get printed on stdout, hence the redirect.
