df is a target utility.
This utility displays statistics about the amount of free disk space on the filesystem specified, or on the filesystem of which file is a part. Values are displayed in 512-byte per block block counts. If neither a file nor a filesystem operand is specified, statistics for all mounted filesystems are displayed (subject to the -t option below).
The following options are available:
Include statistics on the number of free inodes.
Print out the previously obtained statistics from the filesystems. This option should be used if there is a possibility that one or more filesystems are in a state such that they will not be able to provide statistics without a long delay. When this option is specified, df will not request new statistics from the filesystems, but will respond with the (possibly) stale statistics that were previously obtained.
Only print out statistics for filesystems of the specified types. The recognized types are: ufs, nfs, mfs, lfs, msdos, fdesc, portal, kernfs, procfs, afs and isofs. The aggregates are: all (the default), local (ufs, mfs, lfs, msdos, isofs), and misc (fdesc, portal, kernfs, procfs). The string ``no'' may be prepended to a type to get its complement (for example, ``nonfs'' to get non-NFS filesystems). The first -t option overrides the default, additional such options will add to (or subtract from) the current set of types; for example, either df -t ufs -t lfs or df -t local -t nomfs will display statistics for UFS and LFS filesystems. On top of ChorusOS ufs and nfs are only supported for df.
If the environment variable BLOCKSIZE is set, the block counts will be displayed in units of the size specified.
The -n and -t flags are ignored if a file or filesystem is specified.
