tutorial% df Filesystem kbytes used avail capacity Mounted on /dev/ip0a 7445 4714 1986 70% / /dev/ip0g 42277 35291 2758 93% /usr
Note that used+avail is less than the amount of space in the file system (kbytes); this is because the system reserves a fraction of the space in the file system to allow its file system allocation routines to work well. The amount reserved is typically about 10%; this may be adjusted using tunefs. When all the space on a file system except for this reserve is in use, only the super-user can allocate new files and data blocks to existing files. When a file system is overallocated in this way, df may report that the file system is more than 100% utilized.
If arguments to df are disk partitions (for example, /dev/ip0a) or UNIX path names, df produces a report on the file system containing the named file. Thus "df ." shows the amount of space on the file system containing the current directory.
