SYNOPSIS

df [OPTION]... [FILE]...

DESCRIPTION

Show information about the file system on which each FILE resides, or all file systems by default.

Mandatory arguments to long options are mandatory for short options too.

include pseudo, duplicate, inaccessible file systems
scale sizes by SIZE before printing them; e.g., '-BM' prints sizes in units of 1,048,576 bytes; see SIZE format below
print sizes in powers of 1024 (e.g., 1023M)
print sizes in powers of 1000 (e.g., 1.1G)
list inode information instead of block usage
like --block-size=1K
limit listing to local file systems
do not invoke sync before getting usage info (default)
use the output format defined by FIELD_LIST, or print all fields if FIELD_LIST is omitted.
use the POSIX output format
invoke sync before getting usage info
elide all entries insignificant to available space, and produce a grand total
limit listing to file systems of type TYPE
print file system type
limit listing to file systems not of type TYPE
(ignored)
display this help and exit
output version information and exit

Display values are in units of the first available SIZE from --block-size, and the DF_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment variables. Otherwise, units default to 1024 bytes (or 512 if POSIXLY_CORRECT is set).

The SIZE argument is an integer and optional unit (example: 10K is 10*1024). Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (powers of 1000). Binary prefixes can be used, too: KiB=K, MiB=M, and so on.

FIELD_LIST is a comma-separated list of columns to be included. Valid field names are: 'source', 'fstype', 'itotal', 'iused', 'iavail', 'ipcent', 'size', 'used', 'avail', 'pcent', 'file' and 'target' (see info page).
