Index NAME
df - report file system disk space usage
SYNOPSIS
df[
,OPTION/]... [
,FILE/]...
DESCRIPTION
This manual pagedocuments the GNU version of
df.
dfdisplays the amount of disk space available on the file systemcontaining each file name argument. If no file name is given, thespace available on all currently mounted file systems is shown. Diskspace is shown in 1K blocks by default, unless the environmentvariable POSIXLY_CORRECT is set, in which case 512-byte blocks areused.
If an argument is the absolute file name of a disk device node containing amounted file system,dfshows the space available on that file system rather than on thefile system containing the device node. This version ofdfcannot show the space available on unmounted file systems, because onmost kinds of systems doing so requires very nonportable intimateknowledge of file system structures.
OPTIONS
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. Validfield names are: 'source', 'fstype', 'itotal', 'iused', 'iavail', 'ipcent','size', 'used', 'avail', 'pcent', 'file' and 'target' (see info page).
