NAME

bdf − report number of free disk blocks (Berkeley version)

SYNOPSIS

bdf [-b] [-i] [-l|-L] [-t type | [filesystem| file] ... ]

DESCRIPTION

bdf prints out the amount of free disk space available on the specified filesystem (/dev/dsk/c0d0s0, for example) or on the file system in which the specified file ($HOME, for example) is contained.  If no file system is specified, the free space on all of the normally mounted file systems is printed.  The reported numbers are in kilobytes. 

Options

bdf recognizes the following options:

-b Display information regarding file system swapping. 

-i Report the number of used and free inodes. 

-l In the HP Clustered environment, display information for only HFS and CDFS file systems mounted on the local cnode ( NFS mounts are not displayed). 

-L In the HP Clustered environment, display information for file systems that can be unmounted from the local cnode (includes file systems mounted on the local node and cluster-wide NFS mounts). 

-t type Report on the filesystems of a given type (for example, nfs or hfs). 

WARNINGS

If file system names are too long, the output for a given entry is displayed on two lines. 

bdf does not account for any disk space reserved for swap space, or used for the HFS boot block (8k bytes, 1 per file system), HFS superblocks (8k bytes each, 1 per disk cylinder), HFS cylinder group blocks (1k-8k bytes each, 1 per cylinder group), and inodes (currently 128 bytes reserved for each inode).  Non- HFS file systems may have other items that this command does not account for. 

In the HP Clustered environment, device and mountpoint pathnames are displayed with CDF s expanded.
