<syntaxhighlight lang="bash">

[rrc@pridd ComandosDeLaTerminal]$ df --help Usage: df [OPTION]... [FILE]... 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  scale sizes by SIZE before printing them.  E.g.,
                          '-BM' prints sizes in units of 1,048,576 bytes.
                          See SIZE format below.
     --total           produce a grand total
 -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)
     --output[=FIELD_LIST]  use the output format defined by FIELD_LIST,
                              or print all fields if FIELD_LIST is omitted.
 -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

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).

FIELD_LIST is a comma-separated list of columns to be included. Valid field names are: 'source', 'fstype', 'itotal', 'iused', 'iavail', 'ipcent', 'size', 'used', 'avail', 'pcent' and 'target' (see info page).
