The editor will share with you how to use the df command in Linux. I hope you will get something after reading this article. Let's discuss it together.

The Linux common command df is used to display the available disk space on a disk partition. The default display unit is KB. You can use this command to get information such as how much space the hard disk is occupied and how much space is left.

Df displays information about the disk

Syntax df (option) (parameter) option-an or-- all: contains all file systems;-- block-size=: displays the number of chunks in a specified chunk size;-h or-- human-readable: displays information in a more readable manner;-H or-- si: same as the-h parameter, but is calculated in 1000 Bytes conversion units instead of 1024 Bytes;-I or-- inodes: displays inode information -k or-- kilobytes: specify a chunk size of 1024 bytes;-l or-- local: display only the file system on the local side;-m or-- megabytes: specify a chunk size of 1048576 bytes;-- no-sync: do not execute the sync instruction, which is the default value before getting disk usage information;-P or-- portability: use the POSIX output format;-- sync: execute the sync instruction before getting disk usage information -t or-- type=: displays only disk information of the specified file system type;-T or-- print-type: displays the type of file system;-x or-- exclude-type=: does not display disk information of the specified file system type;-- help: displays help;-- version: displays version information. Parameter file: specifies the file on the file system.

The size format displays values in units of-- block-size and the first available SIZE in the DF_BLOCK_SIZE,BLOCK_SIZE and BLOCKSIZE environment variables. Otherwise, the unit defaults to 1024 bytes (512 if POSIXLY_CORRECT is set).

SIZE is an integer and an optional unit (for example: 10m is 10 * 1024 * 1024). The unit is K ·M ·G ·T ·P ·E ·Z ·Y (the power of 1024) or KB,MB, … (power of 1000).
