What is the physical current directory in UNIX or Linux?

So let's say I'm on my iMac and I change into the /var directory.

Guess what? That's not the true or physical location on the file system.

Just try this and you'll be deceived:

pwd

That command returns this:

/var

But that doesn't resolve all of the symbolic links, so it's not the true location.

To do that, pass the -P flag to the command:

pwd -P

Which now returns the true location:

/private/var

This is useful if you're ever deep in a directory structure that is symlinked, you can always check your sanity and be sure of exactly where you are on the system.
