String sadr\u017ei identifikator procesa koji se u izvornom nazivlje zove <b>PID<\/b> ili identifikator procesa. Ovaj identifikator se u UNIX-u koristi za adresiranje procesa. Sljede\u0107a naredba bit \u0107e poziv fork(). U tom trenutku se stvara gotovo to\u010dna kopija procesa. Za OS to izgleda kao da su u sustavu pokrenute kao da postoje 2 kopije iste programa, koje \u0107e na kraju izvr\u0161enja funkcije fork() zavr\u0161iti. Novo stvoreni proces-dijete (u odnosu na roditeljski proces koji ga je stvorio) vi\u0161e ne\u0107e izvr\u0161avati, po\u010dev\u0161i od funkcije main(). Treba imati na umu da proces-dijete nije to\u010dna kopija procesa-roditelja, posebno jer ima vlastiti adresni prostor, vlastite registre, vlastitu oznaku na izvr\u0161ne upute i sli\u010dno. Tako \u0107e vrijednost koju vra\u0107a pozivaocu funkcije fork() biti razli\u010dita. Konkretno, proces-roditelj \u0107e primiti kao povratnu vrijednost PID procesa djeteta, a dijete \u0107e dobiti vrijednost jednaku 0. S obzirom na te kodove povratka kasnije se mogu razdvojiti procesi i prisiliti svaki od njih da izvr\u0161ava svoj posao. U tom slu\u010daju, izvr\u0161enje ovog programa nije strogo definirano. Nakon razdvajanja na 2 procesa, OS po\u010dinje pratiti njih, kao i planirati njihov rad. U slu\u010daju izvr\u0161avanja na jednogrjadnom procesoru, rad \u0107e nastaviti jedan od procesa, u ovom slu\u010daju - roditeljski, a zatim \u0107e kontrolu preuzeti proces-dijete.

Ovom pozivu se proslje\u0111uju kao argumenti ime izvr\u0161ne datoteke i neki parametri. Nakon toga dolazi do u\u010ditavanja koda i stati\u010dkih podataka iz te izvr\u0161ne datoteke i prepisivanja vlastitog segmenta s kodom. Ostali dijelovi memorije, poput stoga i hrpe, ponovo se inicijaliziraju. Nakon \u010dega OS jednostavno izvr\u0161ava program, proslje\u0111uju\u0107i mu skup argumenata. Dakle, nismo stvarali novi proces, ve\u0107 smo jednostavno transformirali trenutno pokrenuti program u drugi pokrenuti program. Nakon izvr\u0161avanja poziva exec() u potomku se stvara dojam da izvorni program kao da uop\u0107e nije bio pokrenut.<\/p>\n<p>Ovo komplikovanje pokretanja je potpuno normalno za Unix shell, i omogu\u0107ava ovom shellu da izvr\u0161i kod nakon poziva <b>fork()<\/b>, ali prije poziva <b>exec()<\/b>.
