df

 

NAME
　　df - report file system disk space usage

SYNOPSIS
　　df [OPTION]... [FILE]...

DESCRIPTION 
　　This manual page documents the GNU version of df. df displays the amount of disk 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. Disk 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 disk 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 re‐
　　quires very nonportable intimate knowledge 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 (pow‐
　　ers of 1024) or KB,MB,... (powers of 1000).

　　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).
