list inode information instead of block usage

[**-k**](#k)

like --block-size=1K

[**-l**, **--local**](#l)

limit listing to local file systems

[**--no-sync**](#no)

- fstype
- itotal
- iused
- iavail
- ipcent
- size
- used
- avail
- pcent
- file
- target

[**-P**, **--portability**](#P)

use the POSIX output format

[**--sync**](#sync)

invoke sync before getting usage info (non-windows only)

[**-t**, **--type** *<TYPE>*](#t)

limit listing to file systems of type TYPE

[**-T**, **--print-type**](#T)

print file system type

[**-x**, **--exclude-type** *<TYPE>*](#x)

limit listing to file systems not of type TYPE

[**-V**, **--version**](#V)

\[*paths*]

# [EXTRA](#EXTRA)

Display values are in units of the first available SIZE from --block-size, and the DF\_BLOCK\_SIZE, BLOCK\_SIZE and BLOCKSIZE environment variables. Otherwise, units default to 1024 bytes (or 512 if POSIXLY\_CORRECT is set).

SIZE is an integer and optional unit (example: 10M is 10\*1024\*1024). Units are K, M, G, T, P, E, Z, Y (powers of 1024) or KB, MB,... (powers of 1000). Units can be decimal, hexadecimal, octal, binary.
