RE: how to use .section command in asm code?

[Robert Plantz <plantz@xxxxxxxxxx>]

Actually, the terminology is "assembler directive", "assembly directive", "pseudo opcode", "pseudo-operation", or "pseudo-op". They direct the assembler to do things as it assembles the source file. For example, as Sofiane points out, ".section .text" tells the assembler to place what follows in the .text segment of the object code. I recommend reading http://en.wikipedia.org/wiki/Assembly_language

(I recognize that computer programming language terminology is largely English-centric, and that English is not the native language for (probably) most programmers in the world.)

This is not a command.
.section is a keyword related to your assembler syntax, probably gas
in your case.
A binary should have a section containing the code.
with gas we declare it with: .section .text with nasm we declare it
with section .text
We write below this tag all the executable code.
A binary could need data of course we create a section containing all
the data with .section .data with gas.
Your asm source file should be like this:
#some headers here
.section .data
    #initialized data here

.section .text
    global _start
    _start:
           #the executable code
