I can print current directory using pwd, but this gives me the path I navigated to get to where I am.
I need to know which disk/partition current directory is on.

For example, if I create symlink user@pc:~$ ln -s /media/HD1 hard_disk and then navigate to ~/hard_disk and run pwd it will print /home/user/hard_disk.

I would like to get the actual path I'm currently on or better just the actual filesystem I'm currently on, which corresponds to one in df.

pwd -P will give you the physical directory you are in, i.e. the pathname of the current working directory with the symbolic links resolved.

Using df . would give you the df output for whatever partition the current directory is residing on.

Example (on an OpenBSD machine):

$ pwd

/usr/ports

$ pwd -P

/extra/ports

$ df .

Filesystem  512-blocks      Used     Avail Capacity  Mounted on

/dev/sd3a    103196440  55987080  42049540    57%    /extra

To parse out the mountpoint from this output, you may use something like

$ df -P . | sed -n '$s/[^%]*%[[:blank:]]*//p'

/extra

To parse out the filesystem device used, use

$ df -P . | sed -n '$s/[[:blank:]].*//p'

/dev/sd3a

I believe some Linux systems also supports

findmnt --target .

(where --target . can be replaced by -T .) or, for more terse output,

findmnt --output target --noheadings --target .

(where --noheadings may be replaced by -n, and --output target may be replaced by -o target) to get the mountpoint holding the filesystem that the current directory is located on.

Use --output source to get the mounted device node.

As said by Ignacio here, you can use df -P file/goes/here | tail -1 | cut -d' ' -f 1
