The "4" in the ls  output means there are 4 file names which reference 
the same file (i.e. it's a hard link).

For example:
[javoskam at amnesia ~]$ mkdir z
[javoskam at amnesia ~]$ cd z
[javoskam at amnesia z]$ touch abc
[javoskam at amnesia z]$ ln -f abc def
[javoskam at amnesia z]$ touch ghi
[javoskam at amnesia z]$ ls -l
total 0
-rw-rw-r--. 2 javoskam javoskam 0 2010-01-27 10:49 abc
-rw-rw-r--. 2 javoskam javoskam 0 2010-01-27 10:49 def
-rw-rw-r--. 1 javoskam javoskam 0 2010-01-27 10:49 ghi
[javoskam at amnesia z]$ echo "hello there" >>abc
[javoskam at amnesia z]$ ls -l
total 8
-rw-rw-r--. 2 javoskam javoskam 12 2010-01-27 10:50 abc
-rw-rw-r--. 2 javoskam javoskam 12 2010-01-27 10:50 def
-rw-rw-r--. 1 javoskam javoskam  0 2010-01-27 10:49 ghi
