df
df [OPTION]... [FILE]...
Show information about the file system on which each FILE resides, or all file systems by default.
Options
--help-
Print help information.
--all,-a-
include dummy file systems
--block-size=<SIZE>,-B <SIZE>-
scale sizes by SIZE before printing them; e.g. ‘-BM’ prints sizes in units of 1,048,576 bytes
--total-
produce a grand total
--human-readable,-h-
print sizes in human readable format (e.g., 1K 234M 2G)
--si,-H-
likewise, but use powers of 1000 not 1024
--inodes,-i-
list inode information instead of block usage
-k-
like –block-size=1K
--local,-l-
limit listing to local file systems
--no-sync-
do not invoke sync before getting usage info (default)
--output=<FIELD_LIST>-
use output format defined by FIELD_LIST, or print all fields if FIELD_LIST is omitted.
--portability,-P-
use the POSIX output format
--sync-
invoke sync before getting usage info (non-windows only)
--type=<TYPE>,-t <TYPE>-
limit listing to file systems of type TYPE
--print-type,-T-
print file system type
--exclude-type=<TYPE>,-x <TYPE>-
limit listing to file systems not of type TYPE
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 1010241024). 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.
Examples
Display all filesystems and their disk usage (using 512-byte units):
df
Display the filesystem containing the specified file or directory:
df {{path/to/file_or_directory}}
Use [k]ibibyte (1024 byte) units when showing size figures:
df -k
Display information in a portable way:
df -P
