df
df [-It] [-f] file-system
df shows the number of free blocks and free inodes of any mounted file system, directory or mounted resource. It is similar to the MS-DOS chkdsk command. It examines the data stored in the superblocks. The file system may be specified either by device name ( /dev/dsk/cldOs2) or by a direct directory name ( /usr). It uses the following options:
| -1 | Only report on local file systems. |
| -t | Causes the figures for total allocated blocks and inodes to be reported as well as the free blocks and inodes. |
| -f | An actual count of the blocks in the free list is made, rather than taking the figure from the superblock (free inodes are not reported). This option does not print any information about mounted remote resources and can take some time to execute. |
If multiple remote resources are listed that reside on the same file system or a remote machine, each listing after the first one is marked with an asterisk.
