[SOLVED] sudo & bash completion

I have trouble with bash completion and sudo.  e.g. if I type "shut" and hit tab the "shutdown" get autocompleted.  However, "sudo shut" <tab> does not work.  Any ideas?

Re: [SOLVED] sudo & bash completion

I just noticed that adding

complete -cf sudo

to ~/.bashrc breaks completion. As user

$ cd .i
.icons/    .inkscape/ .inputrc   .inputrc~  .irssi/

Who wants to cd to a file? Files are not listed if you remove 'complete -cf sudo' line. Any other way to include the sudo to completion?

Edit:  Don't you get that even without this line...  I just tested both and it seems to happen.

Re: [SOLVED] sudo & bash completion

I thought bash completion was dumb, ie it had no concept of the arguments before in completing a filename. It would be neat if it did though!

Re: [SOLVED] sudo & bash completion

hmm, it worked in ssh connection and now I tested it

$ ssh localhost
$ cd .i
.icons/    .inkscape/ .irssi/

So this is related to ssh then. But still weird and it is not affected by 'complete -cf sudo' line.

Re: [SOLVED] sudo & bash completion

zsh seems to have this clever auto-complete, it doesn't propose files to me on completing cd.

Re: [SOLVED] sudo & bash completion

add this to your .bashrc

complete -cf sudo

Does anyone know the zsh equivalent for this?

Re: [SOLVED] sudo & bash completion

For me, bash doesn't try to cd into files either with bash completion.

Maybe you mean bash' tab completion.
- tab completion is the built-in tab completion in bash (and other shells)
- bash completion is an additional feature for bash (eg package bash-completion ).  I'm not sure if it's installed by default

Re: [SOLVED] sudo & bash completion

What's strange for me is it previously worked in .bashrc. Then it just sort of stopped. Now I have it wrapped in .bashrc and it works:

if [ "$PS1" ]; then
    complete -cf sudo
fi

Actually, i meant sudo completion when going back in the zsh history, but now i'm getting more offtopic..

Re: [SOLVED] sudo & bash completion

Is there a way to enable bash completion with aliases .
I use 'Q' as an alias for 'pacman -Q' .

In zsh  :
$ Q lx (then tab)

$ Q lx
lxappearance    lxlauncher      lxrandr         lxsplit         lxterminal      
lxde-common     lxpanel         lxsession-lite  lxtask

'completion works '

In bash :
$ pacman -Q lx (then 2 tabs)

$ pacman -Q lx
lxappearance    lxlauncher      lxrandr         lxsplit         lxterminal      
lxde-common     lxpanel         lxsession-lite  lxtask

'completion works '
but with :
$ Q lx (then 2 tabs)
'It doesn't work'

At the risk of necro-bumping, I want to add a comment that this is completely incorrect. This thread led me astray. The above command will prevent bash from using the correct completion for commands that follow sudo. It will instead try suggest files as the completion for any commands that follow sudo. See this stack overflow answer.

"the risk"? You've just made a new record by reviving a 12-year old thread.
