It seems like you might be referring to the 'df' command in Unix-like operating systems.

'df' stands for "disk free" and is a command used to display information about the disk space usage of file systems. It shows the total, used, and available disk space for each mounted file system.

The basic syntax of the 'df' command is:

```
df [options] [filesystem]
```

Some common options used with 'df' include:

* '-h' : displays the output in a human-readable format (e.g., KB, MB, GB)
* '-a' : includes all file systems, including those with 0 blocks (e.g., pseudo file systems)
* '-T' : displays the file system type
* '-i' : displays the number of inodes (file system metadata) instead of disk space

Here's an example of how you might use the 'df' command:

```bash
df -h
```

This would display the disk space usage of all mounted file systems in a human-readable format.

Is there something specific you'd like to know about the 'df' command, or would you like help with a related topic?
