Bash directory name completion is different in 13.2

Bash directory name completion is different in 13.2, and not in a good way. There is something unusual about the alii for “ls”.

In .bashrc:

LS_OPTIONS="--literal --color --tabsize=0 --classify"
alias ls="/bin/ls `echo $LS_OPTIONS`"
alias del="rm"
alias ll="ls -lh"

When I enter a partial directory name and hit TAB, I expect the directory name to be completed. Because I have ‘–classify’, the name has a trailing “/”. I like it like that. Now, though, sometimes it does not do that; instead it puts a space after the name rather than the slash, or removes backslashes and quotes.

If I type (<TAB> is the TAB key to auto-complete)
ll 1\ r<TAB>
I get
ll 1 rk forms-front folder
instead of
ll 1\ rk\ forms-front\ folder/

If, however I type
/bin/ls --literal --color --tabsize=0 --classify 1\ r<TAB>
I get
/bin/ls --literal --color --tabsize=0 --classify 1\ rk\ forms-front\ folder/

Also, if I do this:
ll “1 rk forms-front folder”<ENTER>
it works as expected, directory listing.

If I do this instead:
ll “1 rk forms-front folder”<TAB>
I get
ll 1 rk forms-front folder

If I type:
/bin/ls --literal --color --tabsize=0 --classify “1 rk forms-front folder”<TAB>
I get
/bin/ls --literal --color --tabsize=0 --classify 1\ rk\ forms-front\ folder/

I do not understand why there is a difference.
Or how to correct it.

Ok i have 13.2 installed here but i can’t seem to find that alias.

grep -i ls_options ~/.bashrc

grep -i ll ~/.bashrc

grep -i del ~/.bashrc

grep -i ll ~/.bashrc

and

grep -i ls_options /etc/skel/.bashrc

grep -i ll  /etc/skell/.bashrc

grep -i del  /etc/skel/.bashrc

grep -i ll /etc/skel/.bashrc

Checking the value of those aliases

type -a del ll ls
-bash: type: del: not found
ll is aliased to `ls -l'
ls is aliased to `_ls'
ls is /usr/bin/ls
ls is /bin/ls
ls is /usr/bin/X11/ls

Also checking /etc for the value of LS_OPTIONS

echo "$LS_OPTIONS"
-A -N --color=tty -T 0

find /etc -type -exec grep -i ls_options {} +

So is this your own aliases and variable that works for the previous openSUSE version?

Also why the echo and command substitution?

alias ls="/bin/ls `echo $LS_OPTIONS`"

Without those hack simply adding the options to /bin/ls will do.

alias ls="/bin/ls $LS_OPTIONS"

[QUOTE=jetchisel;2678289]Ok i have 13.2 installed here but i can’t seem to find that alias.

find /etc -type -exec grep -i ls_options {} +

Sorry it should be, with the f so find will not complain :slight_smile:

find /etc -type f -exec grep -i ls_options {} +

Yes, and it worked until the upgrade to 13.2.

I have done some more research, here it is.

I have pasted the 13.2 complete.bash in paste.opensuse.org

http://paste.opensuse.org/view/raw/24031469

Now on your 13.2 install compare the output of that link using diff and curl.

diff /etc/profile.d/complete.bash <(curl -Lsf http://paste.opensuse.org/view/raw/24031469)

echo $?

If zero is the output that means the file matches. (Actually diff will print something on your terminal if the file is not identical.)

Here is the complete.bash on 13.1

http://paste.opensuse.org/view/raw/91567219

If you can get your hands (or if you still have a 13.1 install) compare the complete.bash to that url

diff /etc/profile.d/complete.bash <(curl -Lsf http://paste.opensuse.org/view/raw/91567219)

echo $?

Again if zero is the output that means it that file is identical.

Now compare those 2 files and you will see if there has been some changes between the 2.
You can put those url in a variable or you can use curl directly on that url.

thirteen_point_two='http://paste.opensuse.org/view/raw/24031469'
thirteen_point_one='http://paste.opensuse.org/view/raw/91567219'


diff <(curl -Lsf "$thirteen_point_one) <(curl -Lsf "$thirteen_point_two)

And the output is

681a682,685
>       local -i init=$(grep -c _init_completion "${dir}/${cmd}" 2>/dev/null)
>       if ((init > 0)) && ! type -t _init_completion &> /dev/null ; then
>           complete -o default -o bashdefault "${cmd}" &>/dev/null && return 124
>       fi

Which means that there has been some changes in the complete.bash file in 13.2. ( diff output from both file.)

and complete.bash belongs to the package aaa_base-extras which you can get from

rpm -qf /etc/profile.d/complete.bash

That is all what i can tell since i’m not a fan of completion to begin with ( i’m fine with the default ).

Thank you for the discussion about bash completion. I have gotten the same results as you have shown.

I do not think that is the issue, though. I have what should be two identical methods of completing a directory name based on the “alias” function. Yet the result is NOT the same.

The directory name is "1 rk forms-front folder".

LS_OPTIONS="--literal --color --tabsize=0 --classify"
alias ls="/bin/ls $LS_OPTIONS" 
alias ll="ls -lh"

ls 1\ r<TAB>
yields
ls 1\ rk\ forms-front\ folder/

ll 1\ r<TAB>
yields
ll 1 rk forms-front folder

The result using "ls ..." and "ll ..." should have been the same with the "ls" result the desired one.

I have also tried

LL_OPTIONS="--literal --color --tabsize=0 --classify -lh"
alias ll="/bin/ls $LL_OPTIONS"

to get a single alias-ing. It gives the same undesirable result.

FYI,

I tried your aliases in a 13.2 vm and it works as what you would expect (ie your desired result) so maybe some other aliases that is messing with your tab completion.

type -a ll ls 

ll is aliased to `ls -lh'
ls is aliased to `/bin/ls --literal --color --tabsize=0 --classify'
ls is /usr/bin/ls
ls is /bin/ls

is what i have, if you’re running an X server you might have more results.

Well, yes. That was my assumption.

The question has been: What is doing the messing?

$ type -a ll ls
ll is aliased to `/usr/bin/ls --literal --color --tabsize=0 --classify -lh'
ls is aliased to `/usr/bin/ls --literal --color --tabsize=0 --classify'
ls is /usr/bin/ls
ls is /bin/ls
ls is /usr/bin/X11/ls

$ ll /bin/ls
lrwxrwxrwx 1 root root 11 Nov 14 21:17 /bin/ls -> /usr/bin/ls*
$ ll /usr/bin/ls
-rwxr-xr-x 1 root root 112K Oct 15 08:35 /usr/bin/ls*
$ ll /usr/bin/X11/ls
-rwxr-xr-x 1 root root 112K Oct 15 08:35 /usr/bin/X11/ls*

$ diff /usr/bin/ls /usr/bin/X11/ls
