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..)

Answer 1

df -P file/goes/here | tail -1 | cut -d' ' -f 1
