NAME

df -- display free disk space

SYNOPSIS

df [-b | -h | -H | -k | -m | -g | -P] [-ailn] [-t] [-T type] [file | filesystem ...]

DESCRIPTION

The df utility displays statistics about the amount of free disk space on the specified filesystem or on the filesystem of which file is a part.
Values are displayed in 512-byte per block counts. If neither a file or a filesystem operand is specified, statistics for all mounted filesystems are displayed (subject to the -t option below).

The following options are available:

  • -a
  • -h
    • "Human-readable" output.
      Use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte in order to reduce the number of digits to three or less using base 2 for sizes.
  • -T
    • Only print out statistics for filesystems of the specified types. More than one type may be specified in a comma separated list.
  • -k
    Use 1024-byte (1-Kbyte) blocks, rather than the default.
  • -m
    Use 1048576-byte (1-Mbyte) blocks rather than the default.
