Questo comando mostra la quantita' di spazio in un determinato file system. Se non ne viene indicato uno, mostra lo spazio disponibile su tutti i file system presenti nel sistema, mostrato in blocchi da 1K.

  • OPTIONS

Show information about the file system on which each FILE resides, or all file systems by default.

Mandatory arguments to long options are mandatory for short options too.

-a, --all include dummy file systems -B, --block-size=SIZE use SIZE-byte blocks

-h, --human-readable print sizes in human readable format (e.g., 1K 234M 2G)

-H, --si likewise, but use powers of 1000 not 1024

-i, --inodes list inode information instead of block usage

-k like --block-size=1K

-l, --local limit listing to local file systems

--no-sync do not invoke sync before getting usage info (default)

-P, --portability use the POSIX output format

--sync invoke sync before getting usage info

-t, --type=TYPE limit listing to file systems of type TYPE

-T, --print-type print file system type

-x, --exclude-type=TYPE limit listing to file systems not of type TYPE

-v (ignored)

--help display this help and exit

--version output version information and exit

SIZE may be (or may be an integer optionally followed by) one of following: kB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y.
