Hi, I've a problem with sed when using the --in-place option in a mounted
NTFS partition;
$ sed --version

$ echo " test string teste" > x

$ sed --in-place=.bak 's <at> tes.*string <at> TESTE <at> g' x

$ ls -l
-rw-r--r-- 1 maiko users   13 jun  6 23:39  x
-rw-r--r-- 1 maiko users   19 jun  6 23:39  x.bak

$ cat x
 TESTE teste

$ cat x.bak
 test string teste

 So far, so good.

 my /etc/fstab

UUID=1CACB8ABACB88136 /media/FILES ntfs defaults,permissions,noatime 0 0


$ cd /media/FILES

$ echo " test string teste" > x

$ sed --in-place=.bak 's <at> tes.*string <at> TESTE <at> g' x

$ ls -l
---------- 1 maiko users   13 jun  6 23:42  x
-rw-r--r-- 1 maiko users   19 jun  6 23:42  x.bak

$ sudo cat x
 TESTE teste

$ cat x.bak
 test string teste
