Funda indlela yokuchazwa kwe-Syntax yama-Command kunye nale Mizekelo
I- syntax yomyalelo ngowona mithetho yokusebenzisa umyalelo. Kufuneka ufunde indlela yokufunda uqwalaselo lwe-syntax xa ufunda indlela yokusebenzisa umyalelo ukuze uyenze ngokufanelekileyo.
Njengoko mhlawumbi uye wambona apha kwaye mhlawumbi ezinye iiwebhusayithi, imiyalo ye-Prompt Prom, imiyalelo ye- DOS , kunye nemiyalelo eminingi yokugijima ichazwa ngazo zonke iintlobo zokudibanisa, iibakaki, izalathisi, njl. Unokwazi ukubheka nayiphi na i-syntax yomyalelo kwaye wazi ngokukhawuleza ukuba zeziphi iinketho ezifunekayo kwaye zeziphi iindlela onokuzisebenzisa kunye nezinye izinto ongakhetha kuzo.
Qaphela: Ngokuxhomekeka kumthombo, unokubona i-syntax eyahlukileyo xa isetyenziswe ukuchaza imiyalelo. Sisebenzisa indlela iMicrosoft isetyenziswe ngayo ngaphambili, kwaye yonke i-syntax yolawulo esiye sabona kuyo nayiphi na indawo iyafana kakhulu, kodwa khumbula ukuba kufuneka ulandele iqhosha le syntax elibhekiselele kwimithetho oyifunayo kwaye ungacingi ukuba zonke iiwebhusayithi kunye namaxwebhu asebenzisa indlela efanayo.
Qala i-Syntax Key
Inqaku elilandelayo le-syntax lichaza indlela inqaku ngalinye kwi-syntax yomyalelo liza kusetyenziswa ngayo. Zive ukhululekile ukubhekisa oku njengoko sihamba ngeemimiselo emithathu phantsi kwetafile.
| Ukwaziswa | Nentsingiselo |
|---|---|
| Bold | Izinto zeBold zimele zifakwe ngokuchanekileyo njengoko ziboniswayo, oku kuquka nantoni na amagama anesibindi, amaqhekeza, iikholoni, njl. |
| Italic | Izinto ze-Italic yizinto omele zibonelele ngazo. Musa ukuthatha into eqhelekileyo kwaye uyisebenzise kumyalelo njengoko kubonisiwe. |
| S paces | Zonke izithuba kufuneka zithathwe ngokoqobo. Ukuba i-syntax yomyalelo inendawo, sebenzisa loo ndawo xa uqhuba umyalelo. |
| [Umbhalo ngaphakathi kubakaki] | Nayiphi na into ephakathi kwesikhonkco zikhethiweyo. Amabhakethi akufanele athathwe ngokoqobo ukuze ungayisebenzisi xa uqhuba umyalelo. |
| Umbhalo ngaphandle kweebakaki | Nayiphi na isicatshulwa esingaxilwanga kwi-bracket iyadingeka. Kwi-syntax yemiyalelo emininzi, itekisi kuphela engazange lijikelezwe elinye okanye ngaphezulu kubakaki ligama lomyalelo ngokwawo. |
| {Umbhalo ngaphakathi kwiibhondi} | Izinto ezikuyo kwi-brace zikhetho, apho kufuneka ukhethe enye kuphela. Iibrasi akufanele zithathwe ngokoqobo ukuze ungasebenzisi ngazo xa uqhuba umyalelo. |
| I-Vertical | ibha | Imivalo efana nayo isetyenziselwa ukwahlula izinto ngaphakathi kubakaki kunye neebhonki. Musa ukuthatha imivalo engqinelanayo-ungayisebenzisi xa uqhuba imiyalelo. |
| Ellipsis ... | I-ellipsis ithetha ukuba into iya kuphinda iphindwe ngonaphakade. Ungafaki i-ellipsis ngokoqobo xa uqhuba umyalelo kwaye uqaphele ukusebenzisa izikhala kunye nezinye izinto ezifunekayo njengoko kuboniswa xa uphinda izinto. |
Qaphela: Iibhokhwe nazo ngamanye amaxesha zibhekwa njengeibakaki zesikwere, ii-braces zibizwa ngamanye ama-bracket squiggly okanye ii-brackets, kunye nemivalo emele ngamanye amaxesha abizwa ngokuba yimibhobho, imigca ecacileyo, okanye iindawo zokuhamba. Kungakhathaliseki ukuba ubabiza ngokuba ngubani, akufanele kubekho nantoni ekufuneka ithathwe ngokoqobo xa uqhuba umyalelo.
Umzekelo # 1: I-Vol Command
Nantsi i-syntax yomyalelo wokukhupha , umyalelo okhoyo kwi- Prom prompt kuzo zonke iinguqulelo ze-Windows operating system :
ukuhamba [ drive: ]
Igama lokuvota lithe ngqine, elithetha ukuba kufuneka lithathwe ngokoqobo. Kwakhona ngaphandle kwamaphi amabakethi, oku kuthetha ukuba kuyadingeka. Siza kujonga kwiibakaki imihlathi embalwa phantsi.
Ukulandela imoto yindawo. Izikhala kwi-syntax yomyalelo kufuneka zithathwe ngokoqobo, ngoko ke xa uqhuba umyalelo wokukhupha, uya kufuneka ubeke isikhala phakathi kwemoto kunye nantoni na ezayo.
Amakhonkco abonisa ukuba nayiphi na into equle ngaphakathi kwayo iyakhethwa-oko kukuthi akukho imfuneko yokuba umyalelo usebenze kodwa ube yinto ofuna ukuyisebenzisa, kuxhomekeke kwinto osebenzisa ngayo umyalelo. Amabhakethi akasoze athathwe ngokoqobo ukuze angawafaki xa eqhuba umyalelo.
Ngaphakathi kwamakhonkco ligama elidityanisiweyo le- drive , elilandelwa li-colon ngesibindi. Nantoni na eyenziwe yinto efunekayo kufuneka unikezele, ungathathi ngokoqobo. Kule meko, i- drive iyibhekisela kwileta yokuqhuba, ngoko uya kufuna ukunika unobumba we- drive apha. Kanye njengoko kuhamba, ukusuka: kubhalwe ngesibindi, kufuneka ifakwe njengobonisiwe.
Ngokusekelwe kuyo yonke loo ngcaciso, nakhu ezinye iindlela ezifanelekileyo kunye ezingavumelekanga zokwenza umyalelo wokukhupha kwaye kutheni:
ukuhambaIchanekile: Umyalelo wokukhupha unokwenziwa ngokwayo ngenxa yokuqhuba : iyakhethwa ngenxa yokuba ijikelezwe ngabakaki.
vol dUkungavumelekanga: Ngelo xesha, inxalenye yokukhethwa komyalelo isetyenzisiweyo, icacisa ukuqhuba njenge- d , kodwa ikholoni ilibalekile. Khumbula, siyazi ukuba ikholoni ihamba ne drive ngoba ifakwe kwisethi enye yeebakaki kwaye siyazi ukuba kufuneka isetyenziswe ngokoqobo kuba ichanile.
I-vol e: / ipheOkungavumelekanga: I-option / p ayifakwanga kwi-syntax yomyalelo ukwenzela ukuba umyalelo wokukhupha awusebenzi xa usebenzisa.
vol vol:Ichanekile: Kule meko, umqhubi wokuzikhethela : ingxabano isetyenziswe njengoko kuhlosiwe.
Umzekelo # 2: Umyalelo wokuvala
I-syntax echazwe apha yilo myalelo wokuvala kwaye ngokucacileyo luyinkimbinkimbi ngakumbi kunomzekelo womyalelo wokukhupha ngentla. Nangona kunjalo, ukwakha kwizinto owaziyo ngaphambili, kukho ngokwenene kakhulu ukufunda apha:
ukuvalwa [ / i | / l | / s | / r | / g | / a | / p | / h | / e ] [ / f ] [ / m \\ igama lomsebenzisi ] [ / t xxx ] [ / d [ p: | u: ] xx : yy ] [ / c " izimvo " ]
Khumbula ukuba izinto ngaphakathi kubakaki zihlala zikhethiweyo, izinto ezingaphandle kweebakaki zihlala zifunekayo, izinto ezixhasayo kunye nezikhala zihlala zikhona, kwaye izinto eziqhelekileyo ziya kunikwa nguwe.
Umxholo omtsha mzekelo kulo mzekelo ibha yomgca. Imivalo emele ngaphakathi kubakaki ibonisa ukhetho olukhethiweyo. Ngoko kumzekelo ongentla, unako, kodwa akudingeki ukuba ukhethe ukukhetha enye yezinto ezilandelayo xa ukhetha umyalelo wokuvala: / i , / l , / s , / r , / g , / a , / p , / h , okanye / e . Njengama-brackets, imivalo ecacileyo ikhona ukuze ichaze i-syntax yomyalelo kwaye ayifanele ithathwe ngokoqobo.
Umyalelo wokuvala uphinde ukhethe ukhetho lwendawo [ / d [ p: | u: ] xx : yy ] - ngokwenene, ukhetho ngaphakathi kukhetho.
Njengomyalelo wokuvota kuMzekelo # 1 ngasentla, nakhu ezinye iindlela ezivumelekileyo nezingavumelekanga zokusebenzisa umyalelo wokuvala:
ukuvala / r / sUkungavumelekanga: Izinketho ze- r / / s azikwazi ukusetyenziswa kunye. Imivalo ecacileyo ibonisa ukhetho, apho ungakhetha khona kuphela.
Ukuvalwa / sp: 0: 0Ukungavumelekanga: Ukusebenzisa / s kulungile kakuhle kodwa ukusetyenziswa kwep: 0: 0 akunjalo ngenxa yokuba olu khetho lufumaneka kuphela ngekheth / option, endilibele ukuyisebenzisa. Ukusetyenziswa okuchanekileyo bekuya kugcinwa / s / dp: 0: 0 .
ukuvala / r / f / t 0Kuchanekile: Zonke iindlela ezikhethiweyo zisetyenziswe ngokufanelekileyo ngeli xesha. I-option / r ayizange isetshenziswe naluphi na olunye ukhetho ngaphakathi kwesoqoqo lwababakaki, kunye neendlela / f kunye / t ezasetyenziswa njengoko kuchazwe kwi-syntax.
Umzekelo # 3: Ukusetyenziswa kweNet
Umzekelo wethu wokugqibela, makhe sijonge umyalelo wokusebenzisa umnatha , omnye wemithetho yomnatha . I-syntax yomnxeba wokusebenzisa umnxeba unobuncwane obuncinane kangangokuba ndiyifumene ngezantsi ukuze ndicacise ngokulula (jonga i-syntax epheleleyo apha ):
usetyenziso lomnatha [{ devicename | * }] [ \\ igama lomsebenzisi \ sharename [{ password } * }]] [ / uqhubeka: { yewe | akukho }] [ / savecred ] [ / susa ]
Umyalelo wokusebenzisa umnatha unemizekelo emibini yenkcazelo entsha, i-brace. I-brace ibonisa ukuba enye, kwaye enye kuphela, yezinto ezikhethiweyo, ezahlukana nemivalo eyodwa okanye ngaphezulu, iyadingeka . Oku akufani nesikhonkqo esinemivalo ecacileyo ebonisa ukhetho olukhethiweyo.
Makhe sibone ezinye zezinto ezisetyenziswayo ezingavumelekanga kunye nokusetyenziswa kakubi:
usetyenziso lomnatha e: * \\ server \ ifayileIsilungelelanisi: Isethi yokuqala yeebhonki kuthetha ukuba ungacacisa i- devicename okanye usebenzise uhlobo lwe-wildcard * - awukwazi ukwenza zombini. Ukusetyenziswa kwe-net e: \\ iseva \ iifayile okanye ukusetyenziswa kwenetha * \\ iseva \ iifayile ziza kuba ziziindlela ezifanelekileyo zokusebenzisa ukusetyenziswa kweetyala kule meko.
usetyenziso lomnatha * \\ appsvr01 \ umthombo 1lovet0visitcanada / ukuqhubeka: chaIchanekile: Ndiyisebenzise ngokufanelekileyo iindlela ezininzi ekusebenziseni umnatha, kubandakanywa nenketho eyodwa. Ndasebenzisa i- * xa kuyimfuneko ukukhetha phakathi kwayo nokucacisa i- devicename , ndacacise isabelo [ umthombo ] kumncedisi [ appsvr01 ], kwaye ke ukhetha ukucacisa { password } kweso sabelo, 1lovet0visitcanada , endaweni yokunyanzelisa ukusebenzisa ndivuselele enye { * }.
Ndagqiba kwelokuba ndingavumeli le drive entsha ekwabelwana ngayo ukuba ixhunyekwe ngokuzenzekelayo ngexesha elizayo ndiqala ikhompyutheni [ / eqhubekayo: akukho ].
usetyenziso lomnatha / oluqhubekayoUkungavumelekanga: Kulo mzekelo, ndakhetha ukusebenzisa umtshini wokukhetha / oqhubekayo kodwa ndikhohliwe ukufaka ikoloni ecaleni kwayo kwaye ndakulibala ukukhetha phakathi kweendlela ezimbini ezifunekayo, ewe okanye akukho , phakathi kwe-braces. Ukusebenzisa i- net net / okuqhubekayo: ewe bekuya kusetyenziswa ngokusemthethweni kokusetyenziswa kwe-net.
