marked as a duplicate of bug 336081 *** I don't think they are the same...
I looked into it a little bit.
The problem is that when you type "sudo cmd <TAB>", bash-completion will run "complete -p ${cmd##*/}" to get the completion information.
So when typing "sudo /etc/init.d/XXX", it prompts with the options for the command "XXX" instead of "/etc/init.d/XXX".

Mind trying bash-completion-1.2 and finding out what the problem is? Aha, bash-completion-1.2 works.
I will stick to 1.2 for a while then.
I guess the developers switched from "complete -p $cmd"(1.2) to "complete -p ${cmd##*/}"(1.3) to handle the cases like "/bin/xxx <TAB>".
One easy fix may be running "complete -p $cmd" first and running "complete -p ${cmd##*/}" one more time in case the first checking fails.

Thanks for the analysis, could you open a bug report upstream and see what they have to say? Please add the link here. bash-completion-1.2 will be removed from gentoo soon. filed a bug there. https://alioth.debian.org/tracker/index.php?func=detail&aid=313065&group_id=100114&atid=413095 thx It has been fixed upstream in the git tree. James I don't think /etc/init.d/* completion is going to work at all with the modern bash-completion versions. |
