NAME

df − Displays statistics on free disk space

SYNOPSIS

df [-ikn] [-t type] [file | file_system ...]

The df command displays statistics on the amount of free disk space on file_system or on the file system that contains the specified file.

FLAGS

-iReports the number of free inodes.  The number of inodes controls the number of files that can exist in a file system. 

-kCauses the numbers to be reported in kilobytes.  By default, all reported BSD compatible numbers are in 512-byte blocks. 

-nDisplays the previously obtained statistics from all mounted file systems.  Use this flag if it is possible that one or more file systems are in a state such that they will not be able to provide statistics without a long delay (for example, if you have a remote file system on a server that has crashed).  If you specify the -n flag, the df command does not request new statistics from the file systems; for some remote file systems, the statistics displayed may be too obsolete to be useful. 

-t typeDisplays statistics for only the specified file system type.

DESCRIPTION

If neither a file or a file system is specified, statistics for all mounted file systems are displayed. 

System V Compatibility

The root of the directory tree that contains the commands modified for SVID-2 compliance is specified in the file /etc/svid2_path. You can use /etc/svid2_profile as the basis for, or to include in, your .profile.  The file /etc/svid2_profile reads /etc/svid2_path and sets the first entries in the PATH environment variable so that the modified SVID-2 commands are found first. 

The df command, as modified for SVID-2 compliance, accepts one command line option (-t, print space totals) and an optional file system name or device name.  The command displays the mount point, the mounted device, the number of free blocks (in 512-byte quantities), and the number of free inodes.  If the -t option is specified, the command displays, on a separate line following the free block counts, the total number of blocks and inodes for each mounted device.
