Hello prof.
My Linux system will display the number of blocks using 1024 as the
default block size if there is on BLOCKSIZE environment value is set.
If I set the BLOCKSIZE environment value, it will display the result
based on that number.
In our project, the only difference is we use 512 as the default block
size. Am I correct?
In addition, if I change the BLOCKSIZE environment value, the total
number of blocks used by the directory will also change based on that
value.
But, our project requires that
"In addition, for each directory whose contents are displayed, the
total number of 512-byte blocks used by the
les in the directory is displayed on a line by itself immediately
before the information for the les in the
directory.
"
Does that means no matter what environment value I gives, the output
just calculate the number of blocks by using the 512 block size?
However, in such way, it will obey the Linux manual page.
Which calculation method should we use?
I prefer the first method which is based on the environment values.(If
it is not given, then use the default value which is 512)
Thanks
