df

Report free disk space (POSIX)

Syntax:

df [-gknP] [device|directory|file]*

Runs on:

Neutrino

Options:

-g

Display all statvfs() information.

-k

Use 1024-byte units (the default is 512-byte).

-n

Display the filesystem mountpoints and types only.

-P

Display headings for the columns. (Output conforms to POSIX 1003.2/5.8.6.1 format.)

Description:

The df utility displays the amount of free disk space for the given devices, directories, and files.

---

By default, df reports its figures in 512-byte units; if you specify the -k option, is uses 1024-byte units. Any block counts reported by the filesystem are rounded into 512- or 1024-byte units, and df always rounds down (i.e. to reflect whole blocks available). For a filesystem that doesn't use native 512-byte (or multiples thereof) blocks, this will result in round-off errors.
