How many commands did you run that actually *open* dir/foobar?

$ cd /tmp/f
$ l
total 4
drwxrwxr-x  2 guenther  wheel  512 Sep  7 23:18 .
drwxrwxrwt  7 root      wheel  512 Sep  7 22:26 ..
$ mkdir dir dir1
$ echo "this is dir1" > dir1/foobar1
$ mkdir dir/dir1
$ echo "surprise, this is dir/dir1" > dir/dir1/foobar1
$ ln -s dir1/foobar1 dir/foobar
$ ls -d dir*
dir  dir1
$ ls -l dir/foobar
lrwxrwxr-x  1 guenther  wheel  12 Sep  7 23:19 dir/foobar -> dir1/foobar1
$ cat dir/foobar
surprise, this is dir/dir1
$ cd dir
$ cat foobar
surprise, this is dir/dir1
$ cd ../..
$ cat f/dir/foobar
surprise, this is dir/dir1
$


So, what EFFECTIVE FULL PATH does dir/foobar point to?  Is that what
you intended it to point to?
