Hi,
There is a bug in a vfat drivers:
vvv:/dosc/test# echo aaa > filename vvv:/dosc/test# echo bbbb > filename. vvv:/dosc/test# echo ccc > longfilename vvv:/dosc/test# echo dddd > longfilename. vvv:/dosc/test# ls -l total 32 -rw-r--r-- 1 root root 5 Jun 1 17:21 filename -rw-r--r-- 1 root root 5 Jun 1 17:21 filename -rw-r--r-- 1 root root 4 Jun 1 17:21 longfilename -rw-r--r-- 1 root root 5 Jun 1 17:21 longfilename. vvv:/dosc/test# cat filename bbbb vvv:/dosc/test# cat filename. cat: filename.: No such file or directory vvv:/dosc/test# rm filename. rm: filename.: No such file or directory vvv:/dosc/test# rm filename vvv:/dosc/test# ls -l total 24 -rw-r--r-- 1 root root 5 Jun 1 17:21 filename -rw-r--r-- 1 root root 4 Jun 1 17:21 longfilename -rw-r--r-- 1 root root 5 Jun 1 17:21 longfilename. vvv:/dosc/test# cat filename bbbb
I.e. Linux lets one to create a two files with the same name in one directory. This happens when filenames have the form of short MS-DOG filename without and with a period. To correct this bug, the vfat drivers should treat names like `file.' as long filenames with trailing period at the end, and should distinguish these filenames from names like `file.'.
-- With best regards, Vladimir.
