DF !!!DF NAME SYNOPSIS DESCRIPTION OPTIONS AUTHOR REPORTING BUGS COPYRIGHT SEE ALSO ---- !!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 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. !!OPTIONS Show information about the filesystem on which each FILE resides, or all filesystems by default. __-a__, __--all__ include filesystems having 0 blocks __--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__, __--kilobytes__ like __--block-size__=''1024'' __-l__, __--local__ limit listing to local filesystems __-m__, __--megabytes__ like __--block-size__=''1048576'' __--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 !!AUTHOR Written by Torbjorn Granlund, David !MacKenzie, Larry !McVoy, and Paul Eggert. !!REPORTING BUGS Report bugs to !!COPYRIGHT Copyright 2001 Free Software Foundation, Inc.
