df

$ df

Display all filesystems and their disk usage in human-readable form

$ df -h

Display the filesystem and its disk usage containing the given file or directory

$ df [path/to/file_or_directory]

Display statistics on the number of free inodes

$ df -i

Display filesystems but exclude the specified types

$ df -x [squashfs] -x [tmpfs]

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

This manual page documents the GNU version of df. df displays the amount of space available on the file system containing each file name argument. If no file name is given, the space available on all currently mounted file systems is shown. Space is shown in 1K blocks by default, unless the environment variable POSIXLY_CORRECT is set, in which case 512-byte blocks are used.

If an argument is the absolute file name of a device node containing a mounted file system, df shows the space available on that file system rather than on the file system containing the device node. This version of df cannot show the space available on unmounted file systems, because on most kinds of systems doing so requires very nonportable intimate knowledge of file system structures.

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.

-a, --all

include pseudo, duplicate, inaccessible file systems

-B, --block-size=SIZE

scale sizes by SIZE before printing them; e.g., '-BM' prints sizes in units of 1,048,576 bytes; see SIZE format below

-h, --human-readable

print sizes in powers of 1024 (e.g., 1023M)

-H, --si

print sizes in powers of 1000 (e.g., 1.1G)

-i, --inodes

list inode information instead of block usage

-k

like --block-size=1K

-l, --local

limit listing to local file systems

--no-sync

do not invoke sync before getting usage info (default)

--output[=FIELD_LIST]

use the output format defined by FIELD_LIST, or print all fields if FIELD_LIST is omitted.

-P, --portability

use the POSIX output format

--sync

invoke sync before getting usage info

--total

elide all entries insignificant to available space, and produce a grand total

-t, --type=TYPE

limit listing to file systems of type TYPE

-T, --print-type

print file system type

-x, --exclude-type=TYPE

limit listing to file systems not of type TYPE

-v

(ignored)

--help

display this help and exit

--version

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).
