To help determine what the characters are, I would use the '-b' option with ls.
-b, --escape
print octal escapes for nongraphic characters
For filenames with special characters, I think it's easiest to use a typeglob. Do you have any other files that start with "personnel"? If not,
cd personnel*
would probably place you in that directory. Then just use 'ls' to see if it has files.
rmdir personnel*
would attempt to delete the directory, and would complain if it contained any files. Just make sure you don't have any other directories that start with "personnel".
Unfortunatly I do have another folder called personnel hence cannot do rmdir personnel*
ls -b
personnel\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D\033[D
Do you have Perl? Something like this might work. You would have to uncomment the rmdir line, but I would recommend this only after you know it's printing only the directory name you want to delete.
I'm sure there's a way to escape octal characters in the shell, but I'm not sure how. Another alternative would be to move off all the 'normal' directories to a temporary location until the only one left is the "personnel\033[D.." file. Then rmdir personnel* as above.
tez,
The easiest way to remove it is to do a rm -ri personnel*, this should prompt you for every file/directory, find if there is anything in the directory, just use find, ie if there is not much in the parent directory just do a find . -print.
