NAME

df − report number of free disk blocks and i-nodes

SYNOPSIS

df [-lt] [-f] [-b] [file-system | directory | mounted-resource]

DESCRIPTION

The df command prints out the number of free blocks and free i-nodes in mounted file systems, directories, or mounted resources by examining the counts kept in the super-blocks. 

file-system may be specified either by device name (e.g., /dev/dsk/c1d0s2) or by mount point directory name (e.g., /usr). 

directory can be a directory name.  The report presents information for the device that contains the directory. 

mounted-resource can be a remote resource name.  The report presents information for the remote device that contains the resource. 

If no arguments are used, the free space on all locally and remotely mounted file systems is printed. 

The df command uses the following options:

−l only reports on local file systems. 

−t causes the figures for total allocated blocks and i-nodes to be reported as well as the free blocks and i-nodes. 

−f an actual count of the blocks in the free list is made, rather than taking the figure from the super-block (free i-nodes are not reported).  This option will not print any information about mounted remote resources. 

−b produce output in 4.3 BSD format. 

NOTE

If multiple remote resources are listed that reside on the same file system on a remote machine, each listing after the first one will be marked with an asterisk.
