What is the DF command?

Df displays the amount of disk space taken or available on a given file system. When no arguements are given, the command lists the memory status on every mounted file system. This information can be useful when examining how much space is still available on a machine. Arguements for this command can be a specific file system, a specific file or no arguements to show all filesystems.
