deleting directories with ??? in name
I've written a command line utility to deal with this type of thing. It's called duc. You can get it at: http://ed.lexingrad.net/duc/ duc takes out unprintables, extended ascii set chars, spaces and punctuations, with options to allow you to take out some while leaving others. Also there is a test only option as well as an option to restore spaces. By default it replaces chars with an underscore, but it can optionally delete the offending chars directly. duc is written in assembly. I hope it helps some people out.

Re: deleting directories with ??? in name
Hi Parv, It looks like another directory structure has appeared in the ftp directory that Lynx does not see and that find . -inum inode -delete does not delete. It does have a dot as the first character, with some other non-printing characters, but no /. I haven't yet tried to delete it with emacs or Midnight Commander. Do you still want to look at it?? If so, as I'm not overly conversant with tar (or too much else that's *nix), please send me the 'tar' command you'd like me to archive the directory structure with, and I'll send the result.

[Fwd: Re: deleting directories with ??? in name]
I managed to delete the files by recreating the directory. Not to seem ungrateful, but isn't it a Bad Thing that it is not straightforeward to delete any file on the system (as root, and thwarted merely because of the characters in the name of the file/directory)? I'm not in a position to mangle lynx, but oughtn't it to be able to zap ANY file regardless of its name? (emacs is obtuse to me.) Is this worthy of a PR? Or are there other ways to kill a malconforming file? Why should an annonomous FTP user be able to create a directory tree that the root account of the machine can't traverse and delete normally?

Nah, nevermind; it was probably a bot As a point of discussion, when was the last time you attempted to remove a file dropped by a Windows virus, and were told, no way, Jose` ... (?) I'm guessing that there is more to it than the characters in the name of the file/directory. Remember that the characters we see are ultimately a symbolic representation of another type of data, and it is possible to construct code that would deceive us, or our programs To attempt to answer the issue you describe, on the surface we must assume that this is a limitation of the interface, i.e. whatever shell you are using, whatever shell/API/whatever your application is using. Obviously if it can be created, it can be deleted, under the right circumstances. But your removal tool must be at least as powerful as the one that placed it there; and it's quite possible that whatever did this is a tad more powerful than tcsh or bash I'm sure if you wanted to write a better shell, you'd be told to go right ahead :-) Of more concern to me in this situation would be if this anonymous FTP user put this weird file on your system ... what *else* did he put there? Are you sure he wasn't able to traverse the chrooted ftp homedir? If access was gained to the filesystem at some lower level ... hmm I think you should definitely attempt to analyze whether this machine has been totally compromised...and quite possibly treat it as such...of course, I'm a little overcautious (read A**l) re: security issues like this... ;-) Maybe the security list; or, perhaps better, another thread here to solicit opinions on whether you have aught to fear from this...but, maybe I'm just plain wrong.
