Older 'ls' commands (not Gnu) might do this, if the file name contained a literal carriage return character, but the 'ls' on my system prints a question mark for non-printing/graphic characters. You could try the '-b' option and see what that prints. The Gnu ls uses backslash escapes (\r, \b, \octnum etc.). This might help in searching strace output, if you do try Bob Proulx's suggestion, since you would know the actual character to look for. Also, you ran the above as root. Since the original file is readable by all, what happens if you do the copy as a regular user? -- Bob McGowan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
