NAME

df − report number of free disk blocks

SYNOPSIS

df [ −t ] [ −f ] [ file-systems ]

DESCRIPTION

Df prints out the number of free blocks and free i-nodes available for on-line file systems by examining the counts kept in the super-blocks; file-systems may be specified either by device name (e.g., /dev/rp1) 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.
