df [options] [name]Report the number of free disk blocks and inodes available on all mounted filesystems or on the given name. (Unmounted filesystems are checked with -F.) name can be a device name (e.g., /dev/dsk/0s9), the directory name of a mount point (e.g., /usr), a directory name, or a remote filesystem name (e.g., an NFS filesystem). Besides the options listed, there are additional options specific to different filesystem types or df modules.
-aProvide information about all filesystems, even ones usually marked in /etc/mnttab to be ignored. Solaris only.
-bPrint only the number of free kilobytes.
-ePrint only the number of free files.
-F typeReport on an unmounted filesystem specified by type. Available types can be seen in the file /etc/vfstab.
-gPrint the whole statvfs structure (overriding other print options).
-i/usr/ucb/df only. Show the number of used and available inodes in a format similar to df -k.
-kPrint allocation in kilobytes (typically used without other options). This option produces output in the format traditionally used by the BSD version of df.
-lReport only on local filesystems.
-nPrint only the filesystem type name; with no other arguments, -n lists the types for all mounted filesystems.
-o suboptionsSupply a comma-separated list of type-specific suboptions.
-tReport total allocated space as well as free space.
-VEcho command line but do not execute command.
