Bhala uhlu lwabo bonke abantu okukhulunywa ngabo kulesi sigaba emlandweni we-Unix
Context:Ekuqaleni uhlelo olusha lokusebenza lwalungenawo umfutho wenhlangano, futhi lwalungenawo negama. Kulesi sigaba, uhlelo lokusebenza olusha lwalunguhlelo lokusebenza olulodwa, hhayi olunezinhloso eziningi njengeMultics. Igama elithi Unics (Uniplexed Information and Computing Service, eliphinyiselwa ngokuthi "izinduna"), okuyigama elibhekisela kuMultics (Multiplexed Information and Computer Services), ekuqaleni laphakanyiselwa le phrojekthi ngo-1970. UBrian Kernighan uthi nguye owasungula lo mshini, futhi uyanezela ukuthi "akekho okhumbulayo" ukuthi ubani owasungula indlela yokugcina yokubhala igama elithi Unix. UDennis Ritchie noDoug McIlroy nabo bayamhlonipha uKernighan.  Lapho i-Computing Sciences Research Center ifuna ukusebenzisa i-Unix emshinini omkhulu kune-PDP-7, kuyilapho elinye igatsha lalidinga i-word processor, uThompson noRitchie banezela amakhono okucubungula umbhalo ku-Unix futhi bathola imali ye-PDP-11. Ngokokuqala ngqá ngo-1970, uhlelo lokusebenza lwe-Unix lwaqanjwa ngokusemthethweni futhi lwasebenza ku-PDP-11. Kwangezelelwa uhlelo lokuhlela umbhalo olubizwa ngokuthi i - roff nesihleli sombhalo. Zontathu zabhalwa ngolimi lwe-PDP-11 assembly. AmaBell Labs asebenzisa lolu hlelo lokuqala lokucubungula umbhalo, oluqukethe i - Unix, i - roff, nomhleli, ukuze kusetshenziswe umbhalo wezicelo zamalungelo obunikazi. Ngokushesha i - Roff yaba i - troff, uhlelo lokuqala lokushicilela lwe - electronic olunekhono eligcwele lokuhlela.  Njengoba isimiso sasiba yinkimbinkimbi ngokwengeziwe futhi iqembu labacwaningi lifuna abasebenzisi abengeziwe, isidingo sencwadi yokufundisa saba sobala. I-UNIX Programmer's Manual yashicilelwa ngo-3 Novemba 1971; imiyalo yabhalwa ngefomethi ye- "man page" esasetshenziswa nanamuhla, enikeza imininingwane emfushane yokubhekisa ngokusetshenziswa kanye namaphutha kwisoftware, futhi efaka kuhlu ababhali bezinhlelo zokuthumela imibuzo kubo.  Ngemuva kokuthi eminye iminyango yeBell Labs ithenge i-DEC PDP-11, nabo bakhetha ukusebenzisa i-Unix esikhundleni sohlelo lokusebenza lwe-DEC. Nge-Version 4 yayisetshenziswa kabanzi ngaphakathi kwelabhorethri futhi kwakhiwa i-Unix Support Group, esiza uhlelo lokusebenza ukuthi luphile ngokufaka ngokusemthethweni ukusatshalaliswa kwalo.  Ngo-1973, i-Version 4 ye-Unix yabhalwa kabusha ngolimi lwezinga eliphakeme i-C, ngokuphambene nomqondo ojwayelekile ngaleso sikhathi wokuthi ubunzima kanye nobunzima besistimu yokusebenza kwakudinga ukuthi ibhalwe ngolimi lokuhlanganisa. Ulimi lweC lwavela njengengxenye yoHlelo 2. UThompson noRitchie babenethonya elikhulu ku-Unix yokuqala kangangokuthi uMcIlroy walinganisela ukuthi babhala futhi balungisa cishe imigqa yekhodi engu-100,000 ngalowo nyaka, bethi "[amagama abo] angacatshangwa ngokuphepha ukuthi anamathele cishe kukho konke okungekho okunye okunikezwayo". Nakuba i-assembly ayizange inyamalale emakhasini e-man kuze kube yi-Version 8, ukufudukela ku-C kusikisela ukuthi isofthiwe ingathuthuka, edinga kuphela inani elincane lekhodi elincike emshinini okufanele lithathelwe indawo lapho kuhanjiswa i-Unix kwamanye amapulatifomu wekhompyutha. Kodwa-ke, i-Version 4 ye-Unix yayisenekhodi enkulu ethembele ku-PDP-11 futhi yayingafanele ukuthuthwa. Ukuthuthwa kokuqala kwesinye isiteji kwenziwa eminyakeni emihlanu kamuva (1978) nge-Interdata 8/32.  Uhlelo lokusebenza lwe-Unix lwaqala ukwethulwa ngokusemthethweni ezweni langaphandle ngo-1973 eSymposium on Operating Systems Principles, lapho uRitchie noThompson banikeza khona iphepha. Lokhu kwaholela ezicelweni zohlelo, kodwa ngaphansi kwesinqumo sokuvuma ngo-1956 ekuxazululeni icala lokulwa nokuthengiselana, iBell System (inhlangano yabazali yeBell Labs) yenqatshelwe ukungena kunoma yiliphi ibhizinisi ngaphandle "kwezinsizakalo zokuxhumana ezijwayelekile", futhi kwakudingeka ukuthi inikeze ilayisense noma yimaphi amalungelo obunikazi ayenayo ngesicelo. Ngakho-ke, i-Unix ayikwazanga ukuguqulwa ibe umkhiqizo. Kunalokho iBell Labs yathumela uhlelo ngezindleko zemithombo yezindaba nokuthumela. UKen Thompson waqala ngokuthula ukuphendula izicelo ngokuthumela amakhasethi nama-disc, ngalinye lihambisana <unk> ngokusho kwenganekwane <unk> inothi esayinwe, "Uthando, Ken".
