Display Free Disk Space Statistics

In Unix, to display how much disk space is free on mounted file systems, use the df command. To do so, at the Unix prompt, enter:

df 

This is not the same as your quota; rather, this displays how much space is left on the device or devices designated. The output and capabilities of the df command vary depending on which variety of Unix you are using, so consult the man pages for specifics. However, typically, you can see information about all mounted file systems, including total space, used space, and free space.

To output information on a specific device or file system node, you may also specify the device or node, as in the following example:

df /node_or_dirname 

Replace /node_or_dirname with the name of your chosen file system node or mounted directory name.
