Hello,
The ls -s argument is documented as such:
ls --help output:
-s, --size print the size of each file, in blocks
LS(1) man page:
-s, --size
print the size of each file, in blocks
This leads one to expect some sort of relationship between the size
colum in ls -l output, perhaps with rounding to the nearest block, but
this is not the case.
The -s argument causes ls to print the st_blocks member of the stat
structure shifted, which is:
blkcnt_t st_blocks; /* number of blocks allocated */
..
The st_blocks field indicates the number of blocks allocated to
the file, 512-byte units. (This may be smaller than st_size/512
when the file has holes.)
Clearly the ls help and manual should instead say:
"Size of space allocated for each file, in blocks"
Perhaps with a notice in the manual further explaining potential for
difference between the file size and size in blocks?
Cheers,
Vito Caputo
