[问题] UNIX file system: Block size

[胡说之]

A quick question:

How to determin the block size of a file system in hard disk? In legacy system it's 512 bytes in most cases. Is there a shell command doing the checking?

df .

how about "wc". Need to do some calculation though.

2K are most the cases.

[(df -k ) kbytes column] / [(df) blockes ] = 0.5

Just figuered a work around:

use "mkdir" to set an empty directory, which should use 1 block, then "ls -l [directory]" to see the bytes.
