size -- show size of file or directory
|
|
|
|
syntax: size <pathname>
|
|
|
|
ex: size this
|
|
size =:sys
|
|
size .61=:dir

For a non-directory file, prints file size in blocks and in
|
|
bytes. For a directory, compute and print the sum of the
|
|
sizes of all the files and directories within the directory.
|
|
Wildcards are allowed.
|
|
|
|
The total size in BYTES of a directory is often MUCH smaller
|
|
than 512 times its size in BLOCKS, even though all blocks
|
|
are 512 bytes long. This is because not all the bytes of a
|
|
file's last block are used. As an extreme example, a
|
|
directory containing 12 files of one byte each would have a
|
|
size of 13 blocks (1 for the directory and 1 each for the
|
|
files), but only 524 bytes (512 for the directory block and
|
|
1 each for the files).
|
|
|
|
(Note that the size reported for a volume directory includes
|
|
actual directory blocks but omits the 2 boot blocks and the
|
|
bitmap block(s). There is one bitmap block for every 4096
|
|
blocks on the volume.)
