Hi,

From: man:ls
............................................................................
SIZE may be (or may be an integer optionally followed by) one of following:
kB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y.
............................................................................

From: info:/coreutils/Block size
............................................................................
...
With human-readable formats, output sizes are followed by a size letter such
as `M' for megabytes. `BLOCK_SIZE=human-readable' uses powers of 1024; `M'
stands for 1,048,576 bytes. `BLOCK_SIZE=si' is similar, but uses powers of
1000 and appends `B'; `MB' stands for 1,000,000 bytes.
...

 `MB'
      megabyte: 10^6 = 1,000,000.

 `M'
 `MiB'
      mebibyte: 2^20 = 1,048,576.
............................................................................

Commands:
............................................................................
#1 ls -l  file.ogg
-r--r--r-- 1 user group 59802045 2010-07-01 20:37 file.ogg

#2 ls -l --si  file.ogg
-r--r--r-- 1 user group 60M 2010-07-01 20:37 file.ogg

#3 ls -l --human-readable  file.ogg
-r--r--r-- 1 user group 58M 2010-07-01 20:37 file.ogg

#4 ls -l --block-size=si  file.ogg
-r--r--r-- 1 user group 60M 2010-07-01 20:37 file.ogg

#5 ls -l --block-size=human-readable  file.ogg
r--r--r-- 1 user group 58M 2010-07-01 20:37 file.ogg
............................................................................

Given the above:

SI Decimal (Matches #2):
59802045/(1000*1000) = roundup(59.80,0) = 60 MB

IEC Binary (Matches #3):
59802045/(1024*1024) = roundup(57.03,0) = 58 M

Shouldn't the `ls -l --si` output (#2 or #4) be display as 60MB vs 60M or
am I just missing a `ls` option for formatting the different display units?

Thank you.
Peggy Russell

That would be more consistent, yes.  But it would also take up an extra
column of output, and those columns are precious.
