NAME

df − disk free

SYNOPSIS

df [ −i ] [ −l ] [ filesystem ... ] [ file ... ]

DESCRIPTION

Df prints out the number of free blocks available on the specified filesystem, e.g. "/dev/rw0a".  If no file system is specified, the free space on all of the normally mounted file systems is printed. 

The reported numbers are in file system block units.  Each filesystem block is 512 bytes long. 

Other options are:

−i Report also the number of inodes which are used and free. 

−l examines also the free list, double checking that the summary number in the filesystem superblock is correct. 

EXAMPLE

df /dev/rw0a

would report the number of free disk blocks [512 bytes each] on /dev/rw0a. 

FILES

/etc/checklistlist of normally mounted filesystems
