The DF command is a commonly used command for viewing hard disk information. The main parameters are as follows:

 

DF-A: displays the disk usage of all file systems, including 0 block file systems.
DF-I: displays the I node information, not the disk block.
DF-T: displays the disk space usage of each specified type of file system.
DF-X: List disk space usage of a file system of a specified type.
DF-T: displays the file system type.
DF in 512 bytes DF-K: in 1024 bytes
DF-M: In megabytes

 

Note 1: Is there a limit on the maximum number of files in the Unix/Linux directory? This can be viewed through DF-I. Because each file has its own inode node, you can determine it.
