Df

NAME

df - report filesystem 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 filesystem containing each  file name argument. If no file name is given, the space available on all currently mounted filesystems 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 contain- ing a mounted filesystem, df shows the space available on that filesys- tem rather than on the filesystem containing the device node (which is       always  the root filesystem). This version of df cannot show the space available on unmounted filesystems, because on most kinds  of  systems doing so  requires  very  nonportable intimate knowledge of filesystem structures.

OPTIONS

Show information about the filesystem on which each FILE  resides,  or       all filesystems by default.

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

-a, --all include filesystems having 0 blocks

-B, --block-size=SIZE use SIZE-byte blocks

-h, --human-readable print sizes in human readable format (e.g., 1K 234M 2G)

-H, --si likewise, but use powers of 1000 not 1024

-i, --inodes list inode information instead of block usage

-k    like --block-size=1K

-l, --local limit listing to local filesystems

--no-sync do not invoke sync before getting usage info (default)

-P, --portability use the POSIX output format

--sync invoke sync before getting usage info

-t, --type=TYPE limit listing to filesystems of type TYPE

-T, --print-type print filesystem type

-x, --exclude-type=TYPE limit listing to filesystems not of type TYPE

-v    (ignored)

--help display this help and exit

--version output version information and exit

SIZE may be (or may be an integer optionally followed by) one of  fol- lowing: kB 1000, K 1024, MB 1,000,000, M 1,048,576, and so on for G, T,      P, E, Z, Y.
