Displaying Information About Files and Disk Space

This table summarizes the commands available for displaying information about file size and disk space.

How to Display Information About Files and Disk Space

• Display information about how disk space is used by using the df command.

  $ df [directory]  [-h] [-t]

  df

  With no options, lists all mounted file systems and their device names, the number of 512-byte blocks used, and the number of files.

  directory

  Specifies the directory whose file system you want to check.

  -h

  Displays disk space in the power of 1024 scaling.

  -t

  Displays the total blocks as well as the blocks used for all mounted file systems.

Example 13-1 Displaying Information About File Size and Disk Space

In the following example, all the file systems listed are locally mounted except for /usr/dist.
