Barnaamijyada bash - qaybta 2

Qaybta labaad tan tababarka-yar barnaamij ka Man uted, meesha aan ku baranno sida loo isticmaalo wareegyada iyo aalado kale oo naga caawin doona hagaajinta howlahayaga qoraallo.

The Hadday shuruud leedahay

Hawsha If waa in la dalbado shaandho oo lagu sameeyo hawl ama hawl nooc kasta oo shaandheeye la adeegsado ah. Qaab dhismeedkeedu waa sida soo socota:

Haddii [xaalad]; markaa elif ayaa amraya [xaalad]; markaa midkale ayaa amraya; amarrada fi

Tusaale ayaa lagu muujiyey ag-marinta Loop ee qaybtiisa u gaarka ah.

Wareegyada

1. In kasta oo: ay fulin doonto dhammaan amarrada lagu caddeeyay inta u dhexeysa sameynta iyo qabashada inta ay xaaladdu run tahay. Haddii aan rabno inaan u gudbinno hawlwadeennada isbarbardhiga, muujinta waa inay ahaataa qaansooyin.

halka XAALAD / AMAR ay amarada sameeyaan

Tusaale: shaxda isku dhufashada ee tiro

#! / bin / bash X = 1 echo "Gali lambar kadibna riix ENTER" aqri M # Xakamaynta loop ee X ka yar ama u dhiganta 10 halka [$ X –le 10] sameeyo # IN R waxaan ku keydinaa isku dhufashada X MR = $ [X * M] # Isku dhufashadan waxaa lagu daabacay shaashadda echo "$ M * $ X = $ R" #Wax ha la sii daayo, waxaan ku kordhineynaa qiimaha X hal cutub hal ha loo sameeyo = X = $ X + 1

2. Loogu talagalay: wuxuu ku kaydiyaa liiska walxaha ku jira doorsoomaha, kaas oo loo isticmaali doono in lagu sameeyo hawlgallo gaar ah oo wareeg kasta ah.

wixii KALA DUWAN ee ELEMENTS waxay sameeyaan amarro la sameeyo

Tusaale: barnaamij nuqul ka fayl galka ka mid ah u galiya mid kale, oo beddelaya fayl hore.

# / bin / bash #Waxaan aasaasineynaa jihooyinka ilaha iyo meesha loo socdo ORIGIN = / home / user / Downloads DESTINATION = / home / user / Documents # Waxaan iskudareynaa isha cd $ ORIGIN # Dhamaan feylasha, kaliya waxaan rabnaa midka # wac FILE ee FILE gudaha * samee ARCH-DESTINATION = "$ DESTINATION / $ FILE" # -f wuxuu noo sifeeyaa faylasha caadiga ah, maadaama nidaamyadu aysan # fiicnayn. –Ma kala shaandhayso # faylalka "cusub" marka loo eego kuwa # laga helo galka loo socdo haddii [-f $ FILE] && [$ FILE –nt $ ARCH-DESTINATION]; ka dib ku celcelinta "Nuqul ka" $ FILE ... "# waxaan nuqul ka qaadnaa feylka cp cp $ FILE $ ARCH-DESTINATION fi done #Waxaan cd ka baxeynaa galka isha cd

Tusaale kale: qoraal meesha uu isticmaalehu ku qiyaasayo lambar nasiib ah oo uu soo saaray kumbuyuutarka.

# / bin / bash # Lambar aan kala sooc lahayn ayaa laga soosaaray 1 ilaa 10, waxaa # ku keydsan QAYBTA RANDOM = $ [$ RANDOM% 10 + 1] halka [1] echo –n "Gali lambar:" akhri NUM # Isbarbar dhig haddii lambarka uu isticmaalay adeegsaduhu # u dhigmo RANDOM; Xusuusnow inaad u isticmaasho $ si aad u qiimeyso #valval ee doorsoomayaasha oo aadan magacyadooda haddii [“$ NUM –eq“ $ RANDOM ”]; ka dib dhawaaqa "Waad saxday!" # jab wuxuu kuu ogolaanayaa in la joojiyo wareegga inta jaban #Haddii nambarku ka yar yahay RANDOM elif [“$ NUM –gt“ $ RANDOM ”]; markaa ku celceliya "Way ka yar tahay" "Haddii kale, way ka weyn tahay RANDOM kale echo" WAA KA WEYN "fi la qabtay

3. Ilaa: aad ugu eg qaabdhismeedka halka, marka laga reebo in koodhku had iyo jeer fuliyo inta qiimaynta xaaladdu taban tahay, taasi waa, barnaamijku wuxuu sii wadaa fulinta "illaa xaaladdu ka dhacdo"

ilaa CONDITION / COMMAND ay amarada sameeyaan

Tusaale: u daabac lambarada 10-20 siday isugu xigayaan

#! / bin / bash CONT = 20 # Ilaa iyo inta miisku ka yaryahay 10 (-lt, "hoose #than") koodhku waa la fulinayaa ilaa [$ CONT -lt 10]; samee echo "COUNTER $ CONT" # A CONT waxaa laga jarayaa unug ha loo daayo CONT- = 1

4. Xullo: wareeggan ugu dambeeya waa kiis gaar ah, maaddaama guud ahaan loo isticmaalo in lagu sameeyo menus si dhakhso leh. Waxay u shaqeysaa sida loo yaqaan 'Loop'.

xulo VARIABLE LIISKA amarrada la qabtay

Tusaale: sii isticmaaleha awood uu ku sii wado ama ku joojiyo qoraalka.

#! / bin / bash #item waa doorsoomaha ka jawaaba waxa # user uu doorto, Continue iyo Finish waa # fursadaha uu heli karo, in kasta oo xulashooyinka kale lagu dari karo # shey xulasho dheeraad ah ee Continue Finish samee #Haddii isticmaalaha uu doorto joojiso barnaamijka, ka dib nasashada ayaan uga baxeynaa wareegga. haddii [$ item = "Finish"]; markaa jebi fi sameeyey
