NAME

6       df - display status of disk space on file systems

SYNOPSIS

9       /usr/ucb/df [-a] [-i] [-t type] [filesystem...]
10            [filename...]

DESCRIPTION

14       The  df utility displays the amount of disk space occupied by currently
15       mounted file systems, the amount of used and available space,  and  how
16       much of the file system's total capacity has been used.
17
18
19       If  arguments  to  df  are path names, df produces a report on the file
20       system containing the named file. Thus `df   .'  shows  the  amount  of
21       space on the file system containing the current directory.
22

OPTIONS

24       The following options are supported:
25
26       -a         Report  on  all filesystems including the uninteresting ones
27                  which have zero total blocks (that is, auto-mounter).
28
29
30       -i         Report the number of used and free inodes. Print ` * ' if no
31                  information is available.
32
33
34       -t type    Report  on  filesystems of a given type (for example, nfs or
35                  ufs).

EXAMPLES

41
42       A sample of output for df looks like:

44
45         example% df
46         Filesystem   kbytes  used  avail  capacity  Mounted on
47         sparky:/       7445  4714  1986     70%     /
48         sparky:/usr   42277 35291  2758     93%     /usr

53       Note that used+avail is less than the amount of space in the file  sys‐
54       tem  (kbytes);  this  is  because the system reserves a fraction of the
55       space in the file system to allow its file system  allocation  routines
56       to  work  well. The amount reserved is typically about 10%; this can be
57       adjusted using tunefs (see tunefs(1M)). When all the space  on  a  file
58       system except for this reserve is in use, only the super-user can allo‐
59       cate new files and data blocks to existing files. When a file system is
60       overallocated  in  this way, df can report that the file system is more
61       than 100% utilized.
