Executable, ki je dolg 104 byte in izpi\u0161e besedo Pozdrav. Stvar bi bila lahko \u0161e kraj\u0161a, vendar potem ELF header datoteke ne bi bil ve\u010d prepoznaven, zmutiliral bi ga lahko do amena! \ud83d\ude1b Sedaj pa je ELF header skoraj ((V prvih nekaj bytov ELF headerja sem stla\u010dil besedo Pozdrav, tam so bile sicer same ni\u010dle. What a waste of space! ;))) nedotaknjen.<\/p>\n
