title: How to find out the free disk space for a given path on a linux shell?
body: <p>1) I am in some directory
  2) I want to find out how much free space is left there</p>
  
  <p>Is there a simple command that does this? I don't want to look in fstab or whatever, having to map the devices &amp; mount points in my mind in order to determine how much free space I have left.</p>
