I-Bash: Iimeko (ukuba-emva koko-enye)

Molweni 😀

Ngeli xesha ndiza kukubonisa ukuba usenza njani iscript kunye nemeko kwi Bash, eliguqulelwa ngu:

Ukuba i-X into oyifunayo ifezekisiwe, isenzo se-Y senziwe, ukuba asifezekanga kwenziwa elinye inyathelo.

Inkcazo elula akukho 😀

Ngoku, ndicinge imizuzu embalwa malunga nomzekelo wokusebenzisa kwesi sifundo, le ngxaki / ingxaki / imeko elandelayo yenzekile kum:

Sikunxibelelwano lwenkampani yethu, kwaye sifuna ukwazi ukuba ngaba ikhompyuter ye-X ixhunyiwe kwinethiwekhi. Ngale nto senza i elishicilelwe uzakwenza ntoni ping Ngakukhompyuter, kwaye ukuba ikunethiwekhi (Oko kukuthi, ukuba ibuyisela ifayile ping) uya kusixelela ukuba EWE, ikwi-network, kungenjalo (oko kukuthi, ayikho kwinethiwekhi) iyakusixelela ukuba ayikho kwinethiwekhi.

Nje ukuba yenziwe, ngoku ndiza kuchaza indlela yokujikeleza iimeko 🙂

Nantsi ikhowudi:

ping -c 1 DIRECCION-IP
if [ $? -ne 0 ]; then
echo "No está en red"
else
echo "Sí está en red"
fi

Sukuba nexhala, ndiza kukuchazela ngokweenkcukacha oku

ping ngumyalelo esiya kuwusebenzisa, kwaye uya kusixelela ukuba le PC ikunethiwekhi. Ukuxelela ukuba yeyiphi i-PC esifuna ukujonga ukuba ayikho kwinethiwekhi, kufuneka sitshintshe IP ADRESS Ngokucacileyo idilesi ye-IP yePC esifuna ukuyijonga.

Njengoko ubona, ndibeka «-c 1«, Eziyimfuneko kuthi. Xa sikhangela ikhompyuter, le nto ayimisi (i-ping) de sizicinezele [Ctrl] + [C], ke ukubeka «-c 1»Siyakuxelela ukuba wenze isiqinisekiso esinye kuphela (umzamo omnye kuphela we-ping) kwaye akukho enye, oku kuya kuyimisa kwangoko, oko kukuthi… kuya kujonga ukuba ikhompyuter ikunethiwekhi kanye kuphela.

Ukuba unokuthandabuza malunga noku, akukho ntlungu ... batsho njalo kwaye ndingavuya ukukuchazela kwakhona 😉

Ngoku kuza umjikelo, kuba le ndiyichazileyo ayisiyonto ingaphezulu komyalelo / isenzo esiqhelekileyo 😀

if [ $? -ne 0 ]; then
echo "No está en red"
else
echo "Sí está en red"
fi

Ukuze uyiqonde le nto, ndiza kuchaza inkcukacha ebaluleke kakhulu kaBash 🙂

Olona lwazi lukhulu kumxholo ungandichaza njengeliphosakeleyo okanye into enjalo, kodwa ke, ndibhalela ii-novice okanye iingcali ezimbalwa, ukuba nje bayayiqonda ke ilungile 😉

Kwenzeka ukuba ngaphakathi Bash yinto efana 0 y 1Oko kukuthi, uyaphila okanye ufile, xa kusenziwa umthetho okanye isenzo: Nokuba yeyiphi kwenziwe kakuhle Akukho ngxaki (1), okanye bekukho ezinye ingxaki okanye imposiso (0).

Senza isenzo okanye umyalelo we-X, kwaye into esiyenzileyo inokuba yenziwe kakuhle okanye kakubi, inokuba ibenempazamo okanye hayi, kwaye kulapho iinkcukacha zikhona 😉

Ukuba oko sithumela ukukwenza (kule meko: ping -c 1 IP-ADDRESS) khange inike mpazamo kwaye ibe yimpumelelo, ke iya kubuyisa ixabiso: 1 . Ngaphandle koko, kwaye ukuba isenzo (oko kukuthi, i-ping) khange siphumelele, siya kubuyisa ixabiso 0.

 Kwaye okokugqibela, ukuba le khowudi ingentla ithetha ntoni:

Ukuba ixabiso 0 labuyiselwa ngoko

Bonisa umbhalo: «Hayi kwinethiwekhi»

Ngaphandle koko (kwaye ubuye HAYI 0, kodwa 1)

Bonisa umbhalo: «Ukuba ikunethiwekhi«

Oku ndisandul 'ukukuchazela kona, kuyakusinceda kwixa elizayo kwizinto ezininzi, kuba kuluncedo lokwenene ukukwazi ukuthi ukuba inyathelo le-X linike impazamo, yenza isenzo se-Y, kwaye ukuba isenzo u-X khange sinike impazamo, emva koko wenze isenzo se-Z.

Ndiyazi ukuba abanye banokudideka, ke ndiye ndazama ukuyicacisa ngeendlela ezahlukeneyo, ndizama ukwenza ukuba wonke umntu ayiqonde ngandlela thile. Ukuba nabani na ushiywe ekuthandabuzeni, ndixelele.

Ngoku, masenze iscript sethu 😀

Kuya kufuneka silandele amanyathelo kwesi sifundo: I-Bash: Uyenza njani into ebhaliweyo

Ke masikope le khowudi ilandelayo kule fayile (iscript.sh), kwaye ekugqibeleni masithi «Phuma»(Ngaphandle kwezicatshulwa):

ping -c 1 DIRECCION-IP
if [ $? -ne 0 ]; then
echo "No está en red"
else
echo "Sí está en red"
fi

Kuya kujongeka njengoku (khumbula ukuba kuya kufuneka uyitshintshile i-IP-ADDRESS kwi-IP oyifunayo):

Apha ungabona iskripthi esisebenzayo:

% CODE1%

Njengoko ubona, ekugqibeleni usixelela «Ewe ikunethiwekhi»🙂

Into ebalulekileyo apha kukuba bayakuqonda oku malunga neemeko, ke ndikushiyela enye ikhowudi ukuyicacisa kwakhona, kodwa ukusuka kwenye indawo yokujonga.

read "texto"
if [ "$texto" = "3" ]; then
echo "Correcto"
else
echo "Incorrecto"
fi


Oku kuthetha ukuba kulula, ndishiya umgca wenkcazo ngomgca:

Umgca wokuqala: Esikubhalayo, iya kuba lixabiso lokwahluka «imiyalezo»(Ngaphandle kwezicatshulwa).

Umgca we-2: Jonga ukuba umxholo wokungafaniyo (oko besesikubhalile) yi 3.

Umgca wokuqala: Kwimeko yokuba 3, iyakusibonisa isicatshulwa «Correcto»(Ngaphandle kwezicatshulwa).

Umgca we-4: Ngaphandle koko (okt, ukuba kunokwenzeka ukuba asibhalanga 3).

Umgca we-5: Iya kusibonisa isicatshulwa «Ayilunganga»(Ngaphandle kwezicatshulwa).

Umgca we-6: Ukuphela kwemeko.

Njengoko bekwazile ukuqonda, ukuba sibeka Bhala kwaye phakathi kweempendulo eziphindwe kabini («) isicatshulwa, oku kuyakwenza ukuba loo mbhalo uboniswe kwisiphelo sendlela. Oko kukuthi, ukuba sibeka:

echo "esto es una prueba"

Iya kusibonisa isicatshulwa kwisiphelo sendlela: Olu luvavanyo

Kodwa ukubuyela kulo mzekelo wesibini, ndiza kukubonisa ukuba luncedo (kunye nokuphunyezwa) kwesi sikripthi sesibini ngento elula KAKHULU 😀… oqhelekileyo «yimalini 1 + 2?«

Ndikushiya ikhowudi yeskripthi esipheleleyo:

#!/bin/bash
# -*- ENCODING: UTF-8 -*-
echo "¿Cuánto es 1 + 2?"
read "texto"
if [ "$texto" = "3" ]; then
echo "Correcto"
else
echo "Incorrecto"
fi
exit

Nantsi indlela esebenza ngayo iskripthi:

% CODE2%

Kwaye ... akukho nto inokongeza.

Le yinto yokuqala, elula ewe, kodwa ndizamile ukuyicacisa kangangoko kunokwenzeka, kuba ayinguye wonke umntu onomphefumlo wenkqubo, kwaye amaxesha amaninzi kufuneka senze izikripthi ezinje ngezi (okanye ezifanayo), nangayiphi na imeko ndiyathemba ukuba eli nqaku liza kuba luncedo kuwe umntu 🙂

Nawuphi na ukuthandabuza okanye umbuzo, isikhalazo okanye ingcebiso nceda ushiye apha, ndiya kukuvuyela ukukuphendula kwaye ke, sonke siyafunda kancinci a
