It means "the number of links". $ pwd /tmp/z $ touch a $ ln a b $ ls -la total 4 drwxr-xr-x 2 dan wheel 512 Apr 12 12:09 . drwxrwxrwt 8 root wheel 512 Apr 12 12:09 .. -rw-r--r-- 2 dan dan 0 Apr 12 12:09 a -rw-r--r-- 2 dan dan 0 Apr 12 12:09 b "a" and "b" both have a link count of 2. "." has a link count of 2 because it also exists in /tmp as "z". ".." has a link count of 8 because it also exists as "." in /tmp, plus as "tmp" in /, plus as ".." in 5 other subdirectories off /tmp. -- Dan Nelson dnelson@allantgroup.com
