Manpages DFSection: FSF (1)Updated: March 2002 Index Return to Main Contents NAMEdf - report filesystem disk space usageSYNOPSISdf [OPTION]... [FILE]...DESCRIPTIONThis 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 containing a mounted filesystem, df shows the space available on that filesystem 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. OPTIONSShow information about the filesystem on which each FILE resides, or all filesystems by default.
