Displaying Information About Files and Disk Space

Command	Description	Man Page
`df`	Reports the number of free disk blocks and files	`df`(1M)
`du`	Summarizes disk space allocated to each subdirectory	`du`(1)
`find` `-size`	Searches recursively through a directory based on the size specified with the `-size` option	`find`(1)
`ls` `-lh`	Lists the size of a file in the power of 1024 scaling	`ls`(1)

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
