SYNOPSIS

df [ −t ] [ −f ] [ file-systems ]

HP-UX COMPATIBILITY

Level: HP-UX/EXTENDED

Origin: HP

DESCRIPTION

Df prints out the number of free 512-byte blocks and free i-nodes available for on-line file systems by examining the counts kept in the super-block(s); file-systems may be specified either by device name (e.g., /dev/hd7914) or by mounted directory name (e.g., /usr).  If the file-systems argument is unspecified, the free space on all of the mounted file systems is printed. 

The −t flag causes the total allocated block figures to be reported as well. 

If the −f flag is given, only an actual count of the blocks in the free list is made (free i-nodes are not reported).  With this option, df will report on raw devices. 

The file space reported is the space available to the ordinary user.  For more details see MINFREE in fs(5).
