How to find out mount/partition a directory or file is on? (Linux Server)

Question

Is there a Linux command to easily find out which partition/mount a directory or file is on?

(This is probably a RTM question, and I feel guilty for asking it, but somehow, I can't find a good answer on google just yet..)

@ErdemEce that's my point. ina mentioned RTFM, but Google (and what it links to) counts as a manual now :-) — Tyler Collier, Dec 12 '14 at 23:47

getting the mount for a directory to troubleshoot a low diskspace error in order to restart a jenkins node that runs the CI loop for your team's web stack seems awfully like a tool used primarily in programming... — worc, Apr 09 '15 at 18:07
@worc Agree. I have exactly the same issue and got my solution here as the accepted answer below. — Metric Crapton, Jun 16 '15 at 17:51

I get following when I run above command. /dev/mapper/vg_mymachine-lv. how do I know on which primary partition it belongs too. i.e. sda1, sda2, hda1 etc? – nir Apr 20 '15 at 19:33

By looking at your LVM configuration. – Ignacio Vazquez-Abrams Apr 20 '15 at 22:57

Great command! I wouldn't use the piping though. Getting to know information about space (at the same time you get to know about which partition your folder/file is on) is quite amusing as well :) – Matheus Felipe Jun 03 '15 at 17:48

Very nice; here's the same thing done with awk: `df -P /home | tail -1 | awk '{ print $1}'` – scrat.squirrel Feb 05 '18 at 00:09

Gotta admit, I really dislike pure command answers, can you make an edit and explain the options/params used? – John Von Neumann Mar 15 '18 at 00:36
to check websites which are located on /var/www/html `df -P /var/www/html | tail -1 | cut -d' ' -f 1` – Yuseferi Jan 21 '19 at 04:09
