What is the "total" number returned by ls?


What is the "total" number signify? For instance, "total 4" and "total 12". For the record, I did read the man before asking this question, and I couldn't find anything about it (Centos 6 distro). Thank you

Code:
[Michael@devserver NewFolder1]$ man ls
[Michael@devserver NewFolder1]$ ls -l
total 4
-rwxrwxr-x. 1 phped phped 15 Jan  5 07:02 noname3.php
[Michael@devserver NewFolder1]$ ls -la
total 12
drwxrwxr-x. 2 phped phped 4096 Jan  5 07:02 .
drwxrwxr-x. 3 phped phped 4096 Jan  5 07:01 ..
-rwxrwxr-x. 1 phped phped   15 Jan  5 07:02 noname3.php
[Michael@devserver NewFolder1]$

total parameter shows how many blocks occupied by files (at filesystem level).
Try this:
Code:
ls -h -l
it will show output in human-readable form. Blocks count will be replaced with real size.

Thank you Teufel,

Funny how the man doesn't explain this.

It does describe the -h option:

Quote:
-h, --human-readable
with -l, print sizes in human readable format (e.g., 1K 234M 2G)
And give a quick blurb at the bottom but doesn't indicate that the returned "total" value was size:
Quote:
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.
Without having to ask the question, how could I have figured this out by myself?
