Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have a stubborn folder that someone must have created accidentally and that has persisted all this time. I can see it with:

# find /var/www/html -maxdepth 1 -type d

which gives me:

/var/www/html
/var/www/html/files
/var/www/html/.?

unfortunately the question mark there is not the actual character ?, it merely seems to denote that there is no proper glyph and/or translation for that character. So something like rmdir is out of the question. My system has UTF-8 as the default locale as so many modern Ubuntu systems, but admittedly the folder in question may have originated on a RHEL or CentOS box (tared up and unpacked).

# env|grep LANG
LANG=en_US.UTF-8

When trying to cd .\? (as mentioned before it is not actually ?) I get auto-corrected to . by bash and actually end up in /var/www/html/. for some reason. Now if I can't "name" this folder usefully, I cannot access it in any way. How can I get rid of it without putting the whole system in jeopardy?

Now I installed detox already but that only seems to act on files, not folders, according to its documentation and besides it still requires that I be able to name the object somehow to do something with it.

If you change directories to /var/www/html and type ls -aldo any hidden directories show up starting with a .? Like .cache or .config or someting with a . in front –  Scott Stookey Feb 29 '12 at 19:08

rm -i makes rm prompt for confirmation of any file. Just press n for all but that one. –  Rinzwind Feb 29 '12 at 19:15
    
@ScottStookey: the folder in question shows up as .? just like before. Observe: drwxr-xr-x 2 user user 4096 2007-09-03 10:08 .? –  0xC0000022L Feb 29 '12 at 19:17

@Rinzwind: spot on. Thanks so much. Could you please write this up as an answer? Did # rm -ir * then got asked: rm: remove directory .\n'?` which I responded to with a y :) –  0xC0000022L Feb 29 '12 at 19:19

A few suggestions, first try using tab completion

cd /var/www

rm -rf ./.TabTab

Or use find

cd /var/www
find -maxdepth 1 -type d -exec rm -ri '{}' \;

If that fails, try running fsck (from a live CD).

Post any error messages or odd behavior you get

sorry, the first one wouldn't work either way because it uses the same mechanisms I mentioned before rm -rf ./.<TAB><TAB> gives me ./ ../ as options. The second would also remove all other other subfolders. –  0xC0000022L Feb 29 '12 at 19:15
    
the second one does not remove all other subfolders. the i in rm -rfi will invoke a yes/no question before deleting ;) –  Rinzwind Feb 29 '12 at 19:17
    
@Rinzwind: got you, because of the i in there ... so he was slightly earlier then. Will accept this answer then. –  0xC0000022L Feb 29 '12 at 19:20

rm -i * makes rm prompt for confirmation of any file. Just press n for all but that one and press y for the one you want removed.

You can also guess the amount of chars with rm -i .??? for 3 chars (so you do not risc pressing y once too many).

Thanks. Also thanks for pointing out my misconception about the other answer :) –  0xC0000022L Feb 29 '12 at 19:22
    
you are welcome! just keep bodhi.zazen's answer. It's a bit longer than needed as you can see but it's a good answer :) –  Rinzwind Feb 29 '12 at 19:23

If you have only this two directories

/var/www/html/files
/var/www/html/.?

under /var/www/html/, you can remove the one not named files with the command

find . -mindepth 1 -maxdepth 1 ! -name files -exec rm -rf {} \;

Hehe, I am aware of this ugly workaround, but I think the question itself is interesting, because in many cases you may not have a single folder in there ... –  0xC0000022L Feb 29 '12 at 19:21
