Momwe Mungaphunzitsire Zithunzi Zomwe Mungagwiritsire Ntchito Pofanana ndi Zomwe Zili M'kati
Chipolopolo ndi mawonekedwe oyambirira a kulowa malamulo pa Linux. Ndicho, mukhoza kulowa mwachindunji kapena kutchula fayilo (script) yomwe ili ndi ndondomeko ya malamulo omwe ayenera kuchitidwa. Zigawo zimayendetsedwa bwino, ndipo chipolopolo chirichonse chikhoza kupanga chipolopolo chatsopano. Chigoba chatsopano chimaonedwa kuti ndi njira ya mwana-chigwirizano-cha chipolopolo cha makolo chimene chimapanga.
Mwachizolowezi, chigwirizano chimadalira kholo lawo mwakuya kuti ngati njira yoberekayo itha, gawoli limathetsanso. Zotsatira zonse zimachokera ku subshell kupita ku chipolopolo cha makolo.
Mmene Mungapangire Chithunzi
Mu script shell ya Bash, mumapanga kachidutswa kamodzi pogwiritsa ntchito malemba olemba:
#! / bin / bash echo "Musanayambe kugwiritsira ntchito" (chiwerengero = 1 pamene [$ count -le 99] amalembetsa "$ count" kugona 1 ((count ++)) adachita "Finished"Mu chitsanzo, chipikachi chimatsekedwa m'magulu, chomwe chimachititsa kuti icho chichitidwe mu chigawo cha chipolopolo chomwe fayilo ya script ikugwiritsidwa ntchito.
Kuthamanga Kachigawo Chakumbuyo
Pokhapokha mutatsimikiza kuti chigamulochi chiyenera kuchitidwa kumbuyo, chipolopolo cha makolo chimadikirira kuti chitsimikizocho chidziwike musanapitirize ndi zina zonsezo. Komabe, ngati mukufuna kuthamanga mofanana, mumayendetsa kumbuyo, zomwe zimakwaniritsidwa ndi khalidwe la ampersand motsatira ndondomeko yomwe ili pansi pano, monga momwe taonera apa:
#! / bin / bash echo "Musanayambe kugwedeza" (chiwerengero = 1 pamene [$ count -le 99] amalembetsa "$ count" kugona 1 ((kuwerengera ++)) kuchitidwa)Kuthamanga Mipukutu Yambirimbiri mu Parallel
Ngati mumapanga ma subshells monga machitidwe oyambirira , mukhoza kuthamanga ntchito mofanana. Kawirikawiri, njira yogwiritsira ntchito imagwiritsira ntchito mapulosesa kapena mapuloteni osiyanasiyana pa ndondomeko iliyonse ndi subprocess, poganiza kuti pali mapurosesa ambiri kapena mapuloteni ngati pali njira. Apo ayi, ntchito zimaperekedwa kwa mapurosesa omwewo. Zikatero, pulosesa kapena pakati zimasintha nthawi zonse pakati pa ntchito zomwe wapatsidwa mpaka ntchitoyo itatha. Chitsanzo chotsatira chili ndi magawo awiri. Yoyamba ikuwerengera kuyambira 1 mpaka 99, ndi yachiwiri kuchokera 1000 mpaka 1099.
#! / bin / bash echo "Musanayambe kugwiritsira ntchito" (chiwerengero = 1 pamene [$ count -le 99] sanagwiritse ntchito "$ count" kugona 1 ((count ++)) & (count = 1000 pamene [$ count -le 1099] onaninso "$ count" kugona 1 ((kuwerengera ++)) kuchitidwa) & echo "Zatha"Gwiritsani ntchito mawu odikira kuti muwuze njira ya makolo kuti adikire kuti zolembazo zithe kumaliza musanayambe ndi zina zonsezo:
#! / bin / bash echo "Musanayambe kugwiritsira ntchito" (chiwerengero = 1 pamene [$ count -le 99] sanagwiritse ntchito "$ count" kugona 1 ((count ++)) & (count = 1000 pamene [$ count -le 1099] liwuzani "$ count" kugona 1 ((kuwerengera ++)) kuchitidwa) ndi kuyembekezerani kuti "Zatha"Zimagwiritsira Ntchito Zowonjezera
Zomwe zimagwiritsidwa ntchito ndizothandiza pamene malamulo amayenera kuchitidwa kumalo enaake. Ngati lamulo lirilonse likugwiritsidwa ntchito mosiyana, palibe chiopsezo kuti zosintha zosiyana zidzasakanizidwa. Pamapeto pake, zoikidwiratu ndi zolembera zamakono siziyenera kubwezeretsedwanso, popeza chilengedwe cha makolo sichikukhudzidwa ndi zotsatira zake zonse.
Zomwe zimagwiritsidwa ntchito zingagwiritsidwe ntchito m'mafotokozedwe a ntchito kuti athe kuphedwa nthawi zambiri ndi magawo osiyanasiyana.
