Namuhla sizokhuluma nge-bash scripts. Lokhu - izikripthi zomugqa womyalo, ebhalelwe igobolondo le-bash. Akhona amanye amagobolondo afana ne-zsh, tcsh, ksh, kodwa sizogxila ku-bash. Lokhu okubalulekile kuhloselwe wonke umuntu, umbandela kuphela amandla okusebenza kuwo umugqa womyalo Linux.

Izikripthi zomugqa womyalo zingamaqoqo emiyalo efanayo engafakwa isuka kukhibhodi, iqoqwe kube amafayela futhi ihlanganiswe inhloso ethile efanayo. Kulokhu, imiphumela yomsebenzi wamaqembu ingaba ivelu elizimele noma isebenze njengedatha yokufaka yamanye amaqembu. Imibhalo iyindlela enamandla yokwenza ngokuzenzakalelayo izenzo ezenziwa njalo.

Ngakho-ke, uma sikhuluma ngomugqa womyalo, ikuvumela ukuthi wenze imiyalo eminingana ngesikhathi esisodwa ngokuyifaka ihlukaniswe i-semicolon:

pwd ; whoami

Eqinisweni, uma uzame lokhu ku-terminal yakho, iskripthi sakho sokuqala se-bash esibandakanya imiyalo emibili sesibhaliwe. Isebenza kanje. Ithimba kuqala pwd ibonisa ulwazi mayelana nohlu lwamanje olusebenzayo, bese kulandela umyalo whoamiibonisa ulwazi mayelana nomsebenzisi ongene kuye njengo.

Usebenzisa le ndlela, ungahlanganisa imiyalo eminingi ngendlela othanda ngayo kulayini owodwa, okuwukuphela komkhawulo yinani eliphakeme lezimpikiswano ezingadluliselwa ohlelweni. Ungachaza lo mkhawulo usebenzisa umyalo olandelayo:

getconf ARG_MAX

Umugqa womyalo uyithuluzi elikhulu, kodwa kufanele ufake imiyalo kuwo ngaso sonke isikhathi uma uyidinga. Kuthiwani uma sibhala isethi yemiyalo efayeleni bese sibiza lelo fayela ukuze siyenze? Eqinisweni, ifayela esikhuluma ngalo libizwa ngokuthi iskripthi somugqa womyalo.

Isebenza kanjani imibhalo ye-bash

Dala ifayela elingenalutho usebenzisa umyalo touch. Umugqa wawo wokuqala udinga ukukhombisa ukuthi sizosebenzisa liphi igobolondo. Sinentshisekelo ku bash, ngakho-ke umugqa wokuqala wefayela uzoba:

#!/bin/bash

Eminye imigqa kuleli fayela isebenzisa uphawu lwe-hashi ukuze ibonise amazwana igobolondo elingawacubunguli. Nokho, umugqa wokuqala uyicala elikhethekile, kukhona ihashi elandelwa uphawu lwesibabazo (lokhu kulandelana kubizwa ngokuthi sheba) kanye nendlela eya bash, bonisa kusistimu umbhalo owadalelwa wona ngokuqondile bash.

Imiyalo yeShell ihlukaniswa ngokuphakelayo komugqa, amazwana ahlukaniswa uphawu lwe-hash. Nansi indlela ebukeka ngayo:

#!/bin/bash
# This is a comment
pwd
whoami

Lapha, njengakulayini womyalo, ungabhala imiyalo kulayini owodwa, ohlukaniswe ama-semicolon. Nokho, uma ubhala imiyalo emigqeni ehlukene, ifayela lifundeka kalula. Kunoma yikuphi, igobolondo lizozicubungula.

Ukusetha izimvume zefayela lombhalo

Londoloza ifayela ulinikeze igama myscript, futhi umsebenzi wokudala umbhalo we-bash usuzoqedwa. Manje okusele ukwenza leli fayela lisebenze, ngaphandle kwalokho, uma uzama ukuliqhuba, uzohlangabezana nephutha. Permission denied.

Izama ukuqalisa ifayela leskripthi elinezimvume ezilungiselelwe ngokungalungile

Masenze ifayela lisebenze:

chmod +x ./myscript

Manje ake sizame ukukwenza:

./myscript

Ngemva kokusetha izimvume konke kusebenza ngendlela efanele.

Isebenzisa ngempumelelo iskripthi se-bash

Okukhipha umlayezo

Ukuze ukhiphe umbhalo kukhonsoli ye-Linux, sebenzisa umyalo echo. Masisebenzise ulwazi lwaleli qiniso futhi sihlele umbhalo wethu, sengeze izincazelo kudatha ekhishwa yimiyalelo esivele ikuyo:

#!/bin/bash
# our comment is here
echo "The current directory is:"
pwd
echo "The user logged in is:"
whoami

Yilokhu okwenzekayo ngemva kokusebenzisa iskripthi esibuyekeziwe.

Ikhipha imilayezo embhalweni

Manje singabonisa amanothi achazayo sisebenzisa umyalo echo. Uma ungazi ukuthi uhlela kanjani ifayela usebenzisa amathuluzi e-Linux, noma awukaze uwubone umyalo ngaphambilini echo, bheka lokhu impahla.

Ukusebenzisa Okuguquguqukayo

Okuguquguqukayo kukuvumela ukuthi ugcine imininingwane efayeleni lombhalo, njengemiphumela yemiyalo, ukuze isetshenziswe eminye imiyalo.

Akukho lutho olungalungile ngokwenza imiyalo ngayinye ngaphandle kokugcina imiphumela yayo, kodwa le ndlela ilinganiselwe emandleni ayo.

Kunezinhlobo ezimbili zokuguquguquka ezingasetshenziswa kuma-bash scripts:

• Imvelo Eguquguqukayo
• Okuguquguqukayo komsebenzisi

Imvelo Eguquguqukayo

Kwesinye isikhathi imiyalo yegobolondo idinga ukusebenza nedatha ethile yesistimu. Nasi isibonelo sendlela yokubonisa uhla lwemibhalo lwasekhaya lomsebenzisi wamanje:

#!/bin/bash
# display user home
echo "Home for the current user is: $HOME"

Sicela uqaphele ukuthi singasebenzisa okuguquguqukayo kwesistimu $HOME ngezingcaphuno eziphindwe kabili, lokhu ngeke kuvimbele isistimu ekuyiboneni. Yilokhu okutholayo uma usebenzisa lesi simo esingenhla.

Ukusebenzisa okuguquguqukayo kwemvelo kusikripthi

Kuthiwani uma udinga ukubonisa uphawu lwedola esikrinini? Ake sizame lokhu:

echo "I have $1 in my pocket"

Uhlelo luzobona uphawu lwedola kuyunithi yezinhlamvu ecashuniwe futhi lucabange ukuthi sibhekisele kokuguquguqukayo. Iskripthi sizozama ukubonisa inani lokuguquguquka okungachazwanga $1. Lokhu akukhona esikudingayo. Okufanele ngikwenze?

Kulesi simo, ukusebenzisa umlingiswa wokuphunyuka, i-backslash, ngaphambi kophawu lwedola kuzosiza:

echo "I have $1 in my pocket"

Iskripthi manje sizokhipha lokho okulindelekile.

Ukusebenzisa ukulandelana kokuphunyuka ukuze uphrinte uphawu lwedola

Okuguquguqukayo komsebenzisi

Ngaphezu kokuguquguquka kwemvelo, imibhalo ye-bash ikuvumela ukuthi uchaze futhi usebenzise okuguquguqukayo kwakho kusikripthi. Okuguquguqukayo okunjalo kubamba inani kuze kube yilapho iskripthi siqeda ukwenza.

Njengokuguquguquka kwesistimu, okuguquguqukayo komsebenzisi kungafinyelelwa kusetshenziswa uphawu lwedola:
I-TNW-CUS-FMP - ikhodi yephromo yesaphulelo sika-10% kumasevisi ethu, etholakalayo ukuze isebenze zingakapheli izinsuku ezingu-7

#!/bin/bash
# testing variables
grade=5
person="Adam"
echo "$person is a good boy, he is in grade $grade"

Yilokhu okwenzekayo ngemva kokusebenzisa iskripthi esinjalo.

Izinguquko Ngokwezifiso Kuskripthi

Umyalo esikhundleni

Esinye sezici eziwusizo kakhulu zeskripthi se-bash yikhono lokukhipha ulwazi kusuka ekuphumeni komyalo futhi unikeze okuguquguqukayo, okukuvumela ukuthi usebenzise lolu lwazi noma yikuphi kufayela lombhalo.

Kunezindlela ezimbili zokwenza lokhu.

• Ukusebenzisa i-backtick "`"
• Ngokuklama $()

Uma usebenzisa indlela yokuqala, qaphela ukuthi ungafaki uphawu olulodwa lokucaphuna esikhundleni se-backtick. Umyalo kufanele ufakwe ezithonjaneni ezimbili ezinjalo:

mydir=`pwd`

Endleleni yesibili, into efanayo ibhalwe kanje:

mydir=$(pwd)

Futhi iskripthi singagcina sibukeka kanjena:

#!/bin/bash
mydir=$(pwd)
echo $mydir

Ngesikhathi sokusebenza kwayo, ukuphuma komyalo pwdizogcinwa ngokuguquguqukayo mydir, okuqukethwe kwakho, kusetshenziswa umyalo echo, uzoya ku-console.

Iskripthi esilondoloza imiphumela yomyalelo kokuguquguqukayo

Imisebenzi yezibalo

Ukuze wenze imisebenzi yezibalo efayeleni lombhalo, ungasebenzisa i-build like $((a+b)):

#!/bin/bash
var1=$(( 5 + 5 ))
echo $var1
var2=$(( $var1 * 2 ))
echo $var2

Ukusebenza Kwezibalo Kuskripthi

uma-ke lawula ukwakha

Kwezinye izimo, udinga ukulawula ukugeleza kokwenziwa komyalo. Isibonelo, uma inani elithile likhulu kunezinhlanu, udinga ukwenza isenzo esisodwa, ngaphandle kwalokho, esinye. Lokhu kusebenza ezimweni eziningi, futhi lapha isakhiwo sokulawula sizosisiza if-then. Ngendlela yayo elula ibonakala kanje:

if команда
then
команды
fi

Nasi isibonelo esisebenzayo:

#!/bin/bash
if pwd
then
echo "It works"
fi

Kulokhu, uma umyalo wenziwe pwdizoqeda ngempumelelo, umbhalo othi "iyasebenza" uzovezwa kukhonsoli.

Masisebenzise ulwazi esinalo futhi sibhale umbhalo oyinkimbinkimbi. Ake sithi sidinga ukuthola umsebenzisi othile /etc/passwd, futhi uma ukwazile ukuyithola, bika ukuthi ikhona.

#!/bin/bash
user=likegeeks
if grep $user /etc/passwd
then
echo "The user $user Exists"
fi

Yilokhu okwenzekayo ngemva kokusebenzisa lesi script.

Usesho lomsebenzisi

Lapha sisebenzise umyalo grepukucinga umsebenzisi kufayela /etc/passwd. Uma iqembu grepongajwayelekile kuwe, incazelo yayo ingatholakala lapha.

Kulesi sibonelo, uma umsebenzisi etholakala, iskripthi sizobonisa umlayezo ohambisanayo. Kuthiwani uma umsebenzisi engatholakali? Kulokhu, umbhalo uzomane uqedele ukwenza ngaphandle kokusitshela lutho. Singathanda ukuthi asitshele ngalokhu futhi, ukuze sizothuthukisa ikhodi.

uma-ke-ke-ke lawula ukwakha

Ukuze uhlelo lukwazi ukubika kokubili imiphumela yosesho oluyimpumelelo nokwehluleka, sizosebenzisa ukwakhiwa if-then-else. Nansi indlela esebenza ngayo:

if команда
then
команды
else
команды
fi

Uma umyalo wokuqala ubuyisela uziro, okusho ukuthi yenziwe ngempumelelo, isimo sizoba yiqiniso futhi ukubulawa ngeke kuqhubeke eduze kwegatsha. else. Uma kungenjalo, uma okuthile okungeyena uziro kubuyiswa, okungabonisa ukwehluleka, noma umphumela ongelona iqiniso, imiyalo ngemva kwalokho else.

Masibhale umbhalo olandelayo:

#!/bin/bash
user=anotherUser
if grep $user /etc/passwd
then
echo "The user $user Exists"
else
echo "The user $user doesn’t exist"
fi

Ukubulawa kwakhe kwehle kakhulu else.

Ukuqalisa iskripthi esinokwakha uma-ke-ke okunye

Hhayi-ke, ake siqhubeke sizibuze ngezimo eziyinkimbinkimbi. Kuthiwani uma udinga ukubheka isimo esisodwa, kodwa eziningana? Isibonelo, uma umsebenzisi oyifunayo etholakala, umyalezo owodwa kufanele uboniswe, uma esinye isimo sihlangene, omunye umlayezo kufanele uboniswe, njalonjalo. Esimeni esinjalo, izimo esidleke zizosisiza. Kubukeka kanjena:

if команда1
then
команды
elif команда2
then
команды
fi

Uma umyalo wokuqala ubuyisela u-zero, obonisa ukukhishwa kwawo ngempumelelo, imiyalo ekubhulokhi yokuqala izokwenziwa. then, ngaphandle kwalokho, uma isimo sokuqala singamanga futhi uma umyalo wesibili ubuyisela uziro, ibhulokhi yesibili yekhodi izosetshenziswa.

#!/bin/bash
user=anotherUser
if grep $user /etc/passwd
then
echo "The user $user Exists"
elif ls /home
then
echo "The user doesn’t exist but anyway there is a directory under /home"
fi

Embhalweni onjalo, ungakwazi, isibonelo, ukudala umsebenzisi omusha usebenzisa umyalo useradd, uma ukusesha kungazange kukhiqize imiphumela, noma wenze enye into ewusizo.

Ukuqhathaniswa kwezinombolo

Emibhalweni ungaqhathanisa amanani ezinombolo. Ngezansi kunohlu lwemiyalo efanele.

n1 -eq n2Ibuyisela iqiniso uma n1 ngokulinganayo n2.
n1 -ge n2 Ibuyisela iqiniso uma n1ngaphezulu noma ngokulingana n2.
n1 -gt n2Ibuyisela iqiniso uma n1 ngaphezu n2.
n1 -le n2Ibuyisela iqiniso uma n1okuncane noma okulinganayo n2.
n1 -lt n2Ibuyisela iqiniso uma i-n1 ingaphansi n2.
n1 -ne n2Ibuyisela iqiniso uma n1alilingani n2.

Njengesibonelo, ake sizame omunye wabaqhubi bokuqhathanisa. Qaphela ukuthi isisho sivalelwe kubakaki abayisikwele.

#!/bin/bash
val1=6
if [ $val1 -gt 5 ]
then
echo "The test value $val1 is greater than 5"
else
echo "The test value $val1 is not greater than 5"
fi

Yilokhu okuzokhishwa yilo myalo.

Ukuqhathaniswa kwezinombolo emibhalweni

Inani eliguquguqukayo val1ezingaphezu kuka-5, igatsha ligcina libulawa thenu-opharetha wesiqhathaniso kanye nomyalezo ohambisanayo uyavezwa kukhonsoli.

Ukuqhathaniswa kwentambo

Imibhalo ingaphinda iqhathanise amanani eyunithi yezinhlamvu. Ama-opharetha wokuqhathanisa abukeka elula, kodwa imisebenzi yokuqhathanisa iyunithi yezinhlamvu inezici ezithile, esizozithinta ngezansi. Nalu uhlu lwabasebenzisi.

str1 = str2 Ihlola iyunithi yezinhlamvu ngokulingana, ibuyisela iqiniso uma iyunithi yezinhlamvu ifana.
str1 != str2Ibuyisela iqiniso uma iyunithi yezinhlamvu ingafani.
str1 < str2Ibuyisela iqiniso uma str1ngaphansi kwe str2.
str1 > str2 Ibuyisela iqiniso uma str1Ngaphezu kwe str2.
-n str1 Ibuyisela iqiniso uma ubude str1Ngaphezulu kweziro.
-z str1Ibuyisela iqiniso uma ubude str1ilingana noziro.

Nasi isibonelo sokuqhathanisa iyunithi yezinhlamvu kusikripthi:

#!/bin/bash
user ="likegeeks"
if [$user = $USER]
then
echo "The user $user  is the current logged in user"
fi

Njengomphumela wokwenza iskripthi, sithola okulandelayo.

Ukuqhathanisa iyunithi yezinhlamvu emibhalweni

Nasi isici esisodwa sokuqhathanisa iyunithi yezinhlamvu okufanele zishiwo. Okungukuthi, ama-opharetha we-">" kanye ne-"<" kumele aphunyuke nge-backslash, ngaphandle kwalokho iskripthi ngeke sisebenze kahle, nakuba ingekho imilayezo yephutha ezovela. Umbhalo uhumusha ">" uphawu njengomyalelo wokukhipha ukuqondisa kabusha.

Nakhu ukuthi ukusebenza nalaba opharetha kubukeka kanjani ngekhodi:

#!/bin/bash
val1=text
val2="another text"
if [ $val1 > $val2 ]
then
echo "$val1 is greater than $val2"
else
echo "$val1 is less than $val2"
fi

Nansi imiphumela yombhalo.

Ukuqhathaniswa kwentambo, isexwayiso sinikezwe

Sicela uqaphele ukuthi umbhalo, nakuba wenziwe, ukhipha isexwayiso:

./myscript: line 5: [: too many arguments

Ukuqeda lesi sixwayiso, siyaphetha $val2 ngezingcaphuno ezimbili:

#!/bin/bash
val1=text
val2="another text"
if [ $val1 > "$val2" ]
then
echo "$val1 is greater than $val2"
else
echo "$val1 is less than $val2"
fi

Manje konke kusebenza njengoba kufanele.

Ukuqhathaniswa kwentambo

Esinye isici se-opharetha ">" kanye ne-"<" yindlela asebenza ngayo ngezinhlamvu ezinkulu nezincane. Ukuze uqonde lesi sici, masilungise ifayela lombhalo elinokuqukethwe okulandelayo:

Likegeeks
likegeeks

Masiyilondoloze ngokuyiqamba igama myfile, bese ugijima umyalo olandelayo kutheminali:

sort myfile

Izohlunga imigqa efayeleni kanje:

likegeeks
Likegeeks

Ithimba sort, ngokuzenzakalelayo, ihlunga izintambo ngokulandelana okukhuphukayo, okungukuthi, uhlamvu oluncane esibonelweni sethu luncane kunosonhlamvukazi. Manje ake silungiselele iskripthi esizoqhathanisa iyunithi yezinhlamvu efanayo:

#!/bin/bash
val1=Likegeeks
val2=likegeeks
if [ $val1 > $val2 ]
then
echo "$val1 is greater than $val2"
else
echo "$val1 is less than $val2"
fi

Uma uyigijimisa, kuvela ukuthi yonke into iphambene - uhlamvu oluncane manje selukhudlwana kunosonhlamvukazi.

Umyalo wokuhlunga nokuqhathanisa iyunithi yezinhlamvu efayeleni lombhalo

Uma kuqhathaniswa nemiyalelo, osonhlamvukazi bancane kunezinhlamvu ezincane. Ukuqhathanisa izintambo lapha kwenziwa ngokuqhathanisa amakhodi we-ASCII wezinhlamvu, ukuhleleka kohlu ngaleyo ndlela kuncike kumakhodi wezinhlamvu.

Ithimba sort, yona, isebenzisa uhlelo lokuhlunga olucaciswe kuzilungiselelo zolimi lwesistimu.

Ukuhlolwa kwefayela

Mhlawumbe imiyalo elandelayo isetshenziswa kaningi kuma-bash scripts. Zikuvumela ukuthi uhlole izimo ezahlukahlukene mayelana namafayela. Nalu uhlu lwale miyalo.

-d fileIhlola ukuthi ifayela likhona yini futhi liwuhla lwemibhalo.
-e fileIhlola ukuthi ifayela likhona yini.
-f file Ihlola ukuthi ifayela likhona yini nokuthi liyifayela.
-r fileIhlola ukuthi ifayela likhona yini futhi liyafundeka.
-s file ПIhlola ukuthi ifayela likhona yini nokuthi alinalutho.
-w fileIhlola ukuthi ifayela likhona yini nokuthi liyabhaleka.
-x fileIhlola ukuthi ifayela likhona yini futhi liyasebenziseka.
file1 -nt file2 Ihlola ukuthi yintsha yini file1kunokuba file2.
file1 -ot file2Ihlola ukuthi indala yini file1kunokuba file2.
-O file Ihlola ukuthi ifayela likhona yini futhi elomsebenzisi wamanje.
-G fileIhlola ukuthi ifayela likhona yini nokuthi ingabe i-ID yeqembu ifana ne-ID yeqembu lomsebenzisi wamanje.

Le miyalo, kanye neminye eminingi okuxoxwe ngayo namuhla, kulula ukuyikhumbula. Amagama abo, okuyizifinyezo zamagama ahlukahlukene, abonisa ngokuqondile amasheke abawenzayo.

Ake sizame owodwa wemiyalo esebenzayo:

#!/bin/bash
mydir=/home/likegeeks
if [ -d $mydir ]
then
echo "The $mydir directory exists"
cd $ mydir
ls
else
echo "The $mydir directory does not exist"
fi

Lesi script, sohla lwemibhalo olukhona, sizobonisa okuqukethwe kuso.

Ukufaka kuhlu okuqukethwe kohla lwemibhalo

Sikholelwa ukuthi ungazama ngokwakho imiyalo esele; yonke isetshenziswa ngokwesimiso esifanayo.

Imiphumela

Namuhla sikhulume ngokuthi ungaqala kanjani ukubhala izikripthi ze-bash futhi sahlanganisa izinto eziyisisekelo. Eqinisweni, isihloko se-bash programming sikhulu. Lesi sihloko sihumusha ingxenye yokuqala yochungechunge olukhulu lwezinto eziyi-11. Uma ufuna ukuqhubeka khona manje, nalu uhlu lwemisuka yalezi zinto zokusebenza.
