View disk and directory capacity under Linux--df, du

DF: Lists the overall disk usage of the file system;

Du: Evaluating the disk usage of the file system (commonly used to estimate the capacity of the catalog)

DF parameter:

-A: List all file systems, including system-specific/proc and other file systems

-K: Displays each file system in KB capacity

-M: Display the file system in MB capacity

-H: Self-display in GB,MB,KB and other formats that are easier for people to read

-H: Replace m=1024k's carry mode with m=1000k

-T: Along with the file system name for the partition (for example, Ext3) is also listed

-I: Do not use the hard disk capacity, but the number of inode to display

Example:

① under Linux, if DF does not have any parameters, the default is to list all of the system (the file system without special memory and swap) in 1KB capacity.

Filesystem: Indicates which partition the file system is on, so list the device name

1k-blocks: Note that the following number unit is 1KB, can use- h or- m to change the capacity

Used: Unused hard disk space

Available: The remaining disk space size

use%: Disk usage

Mountedon: The directory where the disk is mounted (mount point)

② display of capacity results in an easy-to-read capacity format

③ all special file formats and names in the system are listed

④ the available disk capacity below/etc is displayed in a readable capacity format

⑤ Lists the number of inode numbers currently available in each partition

Du parameters:

- A: Lists all files and directory capacity, because the default is only the amount of files under the statistics directory;

-H: displayed in a more readable capacity format (g/m);

-S: lists the total, not each individual directory that occupies the capacity;

-S: does not include totals under subdirectories, and is somewhat different from-s;

-K : Displays the capacity in kilobytes;

-M : Displays the capacity in megabytes .

Example:

① List all file sizes in the current directory

② with example one, but also lists the file's capacity

③ check the capacity of each directory below the root directory

Unlike DF ,du will find all the file data directly in the file system.

Du-s Displays the total file size (without subdirectories) in the current directory, and du displays the total capacity (including subdirectories) for all files in that directory at the end.
