Hi,
I am running ls -lsh on kubuntu 14.04, here is the output:

gemfield@gemfield-ThinkPad-Edge:~$ ls -ls
4 -rw-rw-r-- 1 gemfield gemfield    9  9 18 23:12 test

gemfield@gemfield-ThinkPad-Edge:~$ ls -lsh
4.0K -rw-rw-r-- 1 gemfield gemfield    9  9 18 23:12 test

the "4" colored by green means 4 blocks, so why becomes 4.0K blocks when add -h option to ls -ls?

gemfield@gemfield-ThinkPad-Edge:~$ uname -a
