  • Nome 
      df - mostra lo spazio usato su disco
  • Sintassi 
      df [OPTION]... [FILE]...
  • Descrizione

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. 

      If an argument is the absolute file name of a disk device node containing a mounted file  system,  df  shows  the
      space  available  on  that file system rather than on the file system containing the device node (which is always
      the root file system).  This version of df cannot show the space available on unmounted file systems, because  on
      most kinds of systems doing so requires very nonportable intimate knowledge of file system structures.
  • 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.
