Or perhaps the Cwd module from perl:

I have tried the following where dpi.txt is a file in /home/user_name
Code:
$ pwd
/home/user_name

realpath dpi.txt
realpath -L dpi.txt
realpath -P dpi.txt

All of these result in /home/user_name/dpi.txt

The perl code output looked a bit odd be seemed to print the same thing. The readlink command gave the same results a realpath.

It looks like findmnt may give me what I need. Skipping allot of stuff,
Code:
├─/mnt/linux_data                     /dev/sdb3   ext4      rw,relatime,seclabel,data=ordered
├─/home                               /dev/sdb3[/01_centos]

This seems to indicate that /home is located on /dev/sdb3/01_centos , which is /mnt/linux_data/01_centos which is expected.
