+df [OPTION]... [FILE]...

+
+Show information about the file system on which each FILE resides,
+or all file systems by default.
+
+## After Help
+
+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).
