corrupted directories, problem in deleting them
linux;directory;rm;character encoding
ls will print non-ASCII characters (or rather, characters not supported in the current locale) as ?.  This is one of the reasons why parsing the output of ls is a bad thing to do.  The output from ls is meant to be looked at.  In some cases, like this, those are not the actual names that exist in the filesystem.Try instead something like (these will delete all files and directories, including /path/to/dir)rm -rf /path/to/dirorfind /path/to/dir -deleteorfind /path/to/dir -exec rm -rf {} +orfind /path/to/dir -print0 | xargs -0 rm -rfModify to fit your needs. To only delete files, add -type f after the path in the find examples, for example.Doing just rm -rf * inside that directory (that's important, the current working directory must be the directory whose files and directories you want to delete) may also be enough.See also Why not parse ls?
