10 documents the GNU version of
13 displays the amount of disk space available on the file system
14 containing each file name argument. If no file name is given, the
15 space available on all currently mounted file systems is shown. Disk
16 space is shown in 1K blocks by default, unless the environment
17 variable POSIXLY_CORRECT is set, in which case 512-byte blocks are
20 If an argument is the absolute file name of a disk device node containing a
23 shows the space available on that file system rather than on the
24 file system containing the device node. This version of
26 cannot show the space available on unmounted file systems, because on
27 most kinds of systems doing so requires very nonportable intimate
28 knowledge of file system structures.
31 Show information about the file system on which each FILE resides,
32 or all file systems by default.
34 Mandatory arguments to long options are mandatory for short options too.
36 \fB\-a\fR, \fB\-\-all\fR
37 include pseudo, duplicate, inaccessible file systems
39 \fB\-B\fR, \fB\-\-block\-size\fR=\fI\,SIZE\/\fR
40 scale sizes by SIZE before printing them; e.g.,
41 \&'\-BM' prints sizes in units of 1,048,576 bytes;
44 \fB\-h\fR, \fB\-\-human\-readable\fR
45 print sizes in powers of 1024 (e.g., 1023M)
47 \fB\-H\fR, \fB\-\-si\fR
48 print sizes in powers of 1000 (e.g., 1.1G)
50 \fB\-i\fR, \fB\-\-inodes\fR
51 list inode information instead of block usage
54 like \fB\-\-block\-size\fR=\fI\,1K\/\fR
56 \fB\-l\fR, \fB\-\-local\fR
57 limit listing to local file systems
60 do not invoke sync before getting usage info (default)
62 \fB\-\-output\fR[=\fI\,FIELD_LIST\/\fR]
63 use the output format defined by FIELD_LIST,
64 or print all fields if FIELD_LIST is omitted.
66 \fB\-P\fR, \fB\-\-portability\fR
67 use the POSIX output format
70 invoke sync before getting usage info
73 elide all entries insignificant to available space,
74 and produce a grand total
76 \fB\-t\fR, \fB\-\-type\fR=\fI\,TYPE\/\fR
77 limit listing to file systems of type TYPE
79 \fB\-T\fR, \fB\-\-print\-type\fR
80 print file system type
82 \fB\-x\fR, \fB\-\-exclude\-type\fR=\fI\,TYPE\/\fR
83 limit listing to file systems not of type TYPE
89 display this help and exit
92 output version information and exit
94 Display values are in units of the first available SIZE from \fB\-\-block\-size\fR,
95 and the DF_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment variables.
96 Otherwise, units default to 1024 bytes (or 512 if POSIXLY_CORRECT is set).
98 The SIZE argument is an integer and optional unit (example: 10K is 10*1024).
99 Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (powers of 1000).
101 FIELD_LIST is a comma\-separated list of columns to be included. Valid
102 field names are: 'source', 'fstype', 'itotal', 'iused', 'iavail', 'ipcent',
103 \&'size', 'used', 'avail', 'pcent', 'file' and 'target' (see info page).
