In Fish, how do I check that two paths are the same?

Question

I'm trying to write an if statement that checks to see if two variables refer to the same file or directory. I can't simply compare the strings, because I want two different strings that refer to the same path.

For example, I would like to check if ./ and ../foobar/ refer to the same directory.

Simply doing test "$path1" -eq "$path2" won't work in some cases.

The answer is found in the documentation for the test command:

Operators to compare files and directories

FILE1 -ef FILE1

Returns true if FILE1 and FILE2 refer to the same file.

Here's an example:

 if test "$path1" -ef "$path2"
      echo "These two variables refer to the same file"
 end

Note that the two paths have to refer to a file or directory that exists. If foobar does not exist, then test foobar -ef foobar will evaluate to false.
