Indlela yokufunda i-Syntax yokuLawula

Funda indlela yokuchazwa ngokuvumelana ne-Command Syntax Ngezibonelo

I- syntax yomyalo ngokuyinhloko imithetho yokusebenzisa umyalo. Udinga ukwazi ukufunda i-syntax notation lapho ufunda ukuthi ungayisebenzisa kanjani umyalo ukuze ukwazi ukuyisebenzisa kahle.

Njengoba kungenzeka ukuthi ubonile lapha futhi mhlawumbe amanye amawebhusayithi, imiyalo ye-Command Prompt , imiyalo ye- DOS , nemilayezo eminingi yokugijima ichazwa nazo zonke izinhlobo zokuhlehla, amabakaki, izithako, njll Uma wazi ukuthi zonke lezi zimpawu zibhekisela kuphi, ungabheka noma iyiphi i-syntax yomyalo futhi wazi ngokushesha lokho okudingekayo okudingekayo nokuthi yiziphi izinketho ezingasetshenziswa ngazo ezinye izinketho.

Qaphela: Kuye umthombo, ungabona i-syntax ehlukile uma isetshenziselwa ukuchaza imiyalo. Sisebenzisa indlela iMicrosoft eseyisebenzise ngayo ngokomlando, futhi yonke imilayezo ye-syntax esake sabona kunoma iyiphi isayithi ifana kakhulu, kodwa khumbula ukuthi kufanele ulandele ukhiye we-syntax oqondene nemilayezo oyifunayo futhi ungacabangi ukuthi konke amawebhusayithi kanye namadokhumenti basebenzisa indlela efanayo.

Vala ukhiye we-Syntax

Ukhiye we-syntax olandelayo uchaza ukuthi ukwaziswa ngayinye ku-syntax yomyalo kuyasetshenziswa kanjani. Zizwa ukhululekile ukubhekisela lokhu njengoba sihamba ngezibonelo ezintathu ngaphansi kwetafula.

Ukwaziswa	Okushoyo
Bold	Izinto ze-Bold kufanele zifakwe kahle njengoba ziboniswa, lokhu kufaka phakathi noma yiliphi amagama ashubile, amahle, amakholoni, njll.
Italic	Izinto ze-italic yizinto okufanele uzinikeze. Ungathathi italikhi ngokoqobo futhi uyisebenzise kumyalo njengoba kubonisiwe.
S paces	Zonke izikhala kufanele zithathwe ngokoqobo. Uma i-syntax yomyalo inesikhala, sebenzisa leso sikhala lapho uqhuba umyalo.
[Umbhalo ngaphakathi kubakaki]	Noma yiziphi izinto ngaphakathi kwe-bracket ziyizikhethelo. Ama-brackets akufanele athathwe ngokoqobo ngakho ungawasebenzisi uma uqhuba umyalo.
Umbhalo ngaphandle kwabakaki	Noma iyiphi imibhalo engekho kubakaki iyadingeka. Ku-syntax yemiyalo eminingi, umbhalo owodwa ongezungezwe ngabakaki abodwa noma ngaphezulu yigama lomyalo ngokwawo.
{Umbhalo ngaphakathi kwamabhande}	Izinto ezingaphakathi kwe-brace yizinketho, okumele ukhethe eyodwa kuphela. Ama-Braces akufanele athathwe ngokoqobo ngakho ungayisebenzisi lapho uqhuba umyalo.
Okuqondile | ibha	Imivimbo eqondile isetshenziselwa ukuhlukanisa izinto ngaphakathi kubakaki nama-braces. Ungathathi imigoqo eqondile ngokuqondile - ungayisebenzisi lapho uqhuba imiyalo.
Ellipsis ...	I-ellipsis isho ukuthi into ingabuyekezwa kuze kube phakade. Ungafaki i-ellipsis ngokoqobo uma uqhuba umyalo futhi unakekele ukusebenzisa izikhala nezinye izinto ezidingekayo njengoba kuboniswa lapho uphinda izinto.

Qaphela: Ama- brackets nawo ngezinye izikhathi abizwa ngokuthi amabakaki wesigcawu, ama-brace ngezinye izikhathi abizwa ngokuthi amabakaki noma ama-brackets amakhanda, futhi imigoqo emibi ngezinye izikhathi ibizwa ngokuthi amapayipi, imigqa eqondile, noma imigqa emibala. Kungakhathaliseki ukuthi ubabiza ngani, akekho okufanele athathwe ngokoqobo uma enza umyalo.

Isibonelo # 1: I-Vol Command

Nansi i-syntax yomyalo we- vol , umyalo otholakala ku- Command Prompt kuzo zonke izinguqulo zesistimu yokusebenza yeWindows:

vol [ drive: ]

Igama lokuvota lisho ngesibindi, okusho ukuthi kufanele kuthathwe ngokoqobo. Kungaphandle kwamanye amabakaki, okusho ukuthi kuyadingeka. Sizobheka amabakaki izigaba ezimbalwa phansi.

Ukulandela imoto kuyindawo. Izikhalazo ze-syntax yomyalo kufanele zithathwe ngokoqobo, ngakho-ke uma uqhuba umyalo wendiza, kuzodingeka ubeke isikhala phakathi kwemoto nokunye okungase kulandele.

Amakhonksi abonisa ukuthi noma yini equkethwe ngaphakathi kwayo iyakhethwa - okunye okukhona akudingeki ukuba umyalo usebenze kodwa kungase ube into ofuna ukuyisebenzisa, kuye ngokuthi yini oyisebenzisayo umyalo. Amabhakede akufanele athathwe ngokoqobo ukuze ungawafaki lapho eqhuba umyalo.

Ngaphakathi kubakaki yi- drive ye -italicized drive , ilandelwa ikholomu ngesibindi. Noma yini eyakhiwe yinto okumelwe uyihlinzeke, ungayithathi ngokoqobo. Kulokhu, idrayivu ibhekisela encwadini yokushayela, ngakho-ke uzofuna ukunikeza incwadi yokushayela lapha. Njengoba nje nge- vol , kusukela: isesibindi, kufanele ifakwe njengoba ibonisiwe.

Ngokusekelwe kulo lonke lolo lwazi, nansi ezinye zezindlela ezivumelekile nezingafanelekile zokwenza umyalo we-vol nokuthi kungani:

i-vol

Kuvumelekile: Umyalo wokuvota ungenziwa ngokwayo ngoba ukushayela : kuyinto ekhethekayo ngoba ibhajwe ngabakaki.

vol d

Okungavumelekile: Lesi sikhathi, ingxenye yokuzikhethela isetshenzisiwe, icacisa ukushayela njenge- d , kepha ikholoni yikhohliwe. Khumbula, siyazi ukuthi ikoloni ihambisana ne drive ngoba ifakwe kwisethi efanayo yabakaki futhi siyazi ukuthi kufanele isetshenziswe ngokoqobo ngoba isibindi.

vol e: / k

Akuvumelekile: I-option / p ayizange ibhalwe kuhlu le-syntax yomyalo ngakho-ke umyalo wokushayela awusebenzi uma usebenzisa.

vol c:

Kuyafaneleka: Kule cala, i- drive yokuzikhethela : ingxabano isetshenziswe njengoba kuhloswe.

Isibonelo # 2: I-Shutdown Command

I-syntax ehlongozwe lapha iwukuba umyalo wokuvala futhi ngokusobala kunzima nakakhulu kunesibonelo somyalo we-vol ngenhla. Nokho, ukwakha kulokho osuvele wazi, empeleni kuncane kakhulu okumele ufunde lapha:

ukuvala [ / i | / l | / s | / r | / g | / a | / p | / h | / e ] [ / f ] [ / m \\ igama lomsebenzisi ] [ / t xxx ] [ / d [ p: | u: ] xx : yy ] [ / c " ukuphawula " ]

Khumbula ukuthi izinto ngaphakathi kubakaki zihlala zikhetha, izinto ezingaphandle kwamakaki zihlale zidingeka, izinto eziqinile futhi izikhala zihlale zikhona, futhi izinto ezibonakalayo kufanele zinikezwe.

Umqondo omusha omusha kulesi sibonelo yi-bar mpo. Imigoqo ephakathi ngaphakathi kubakaki ibonisa ukukhetha okukhethwa kukho. Ngakho esibonelweni esingenhla, ungakwazi, kodwa akudingeki ukuba ukhethe, khetha ukufaka okunye kokukhethwa kukho okulandelayo uma uqhuba umyalo wokuvala: / i , / l , / s , / r , / g , / a , / p , / h , noma / e . Njengabakaki, imigoqo ekhona ikhona ukuze ichaze umyalo we-syntax futhi akufanele uthathwe ngokoqobo.

Umyalo wokuvala ubuye ube nenketho encane ku [ / d [ p: | u: ] xx : yy ] - ngokuyisisekelo, ukhetho ngaphakathi kokukhethwa kukho.

Njengomyalo wemoto ku-Isibonelo # 1 ngenhla, nansi ezinye izindlela ezivumelekile nezingafanele ukusebenzisa umyalo wokuvala:

ukuvala / r / s

Okungavumelekile: Izinketho ze- r / / s azikwazi ukusetshenziswa ndawonye. Le mibhoshongo ekhombisa ukukhetha, ongakhetha eyodwa kuphela.

ukuvala / sp: 0: 0

Akuvumelekile: Ukusebenzisa / s kuhle kakhulu kodwa ukusetshenziswa kwe- p: 0: 0 akulona ngoba lolu khetho luyatholakala kuphela nge-option / / d , engikhohliwe ukuyisebenzisa. Ukusetshenziswa okulungile bekuyovalwa / s / dp: 0: 0 .

ukuvala / r / f / t 0

Kuyafaneleka: Zonke izinketho zisetshenziswe kahle ngalesi sikhathi. I- r / option ayizange isetshenziswe nganoma yikuphi ukukhetha ngaphakathi kweqoqo lababakaki, futhi izinketho / / f kanye / t zisetshenzisiwe njengoba kuchazwe ku-syntax.

Isibonelo # 3: Net Use Command

Ukuze sibone isibonelo sethu sokugcina, ake sibheke umyalo wokusebenzisa inetha , omunye wemilayezo yenetha . I-syntax yokusebenzisa inetha iyinhlamba encane ngakho ngiyifinyelele ngezansi ukuze ngiyiqonde kalula (bheka i-syntax egcwele lapha ):

ukusetshenziswa kwenetha [{ devicename | * }] [ \\ igama lomsebenzisi \ sharename [{ iphasiwedi | * }]] [ / okuphikisanayo: { yebo | akukho }] [ / savecred ] [ / susa ]

Umyalo wokusebenzisa inetha unemibono emibili yesaziso esisha, i-brace. I-brace ikhombisa ukuthi eyodwa, futhi eyodwa kuphela, yezinqumo, ehlukaniswe ngenye imigoqo eyodwa noma ngaphezulu, iyadingeka . Lokhu akufani nesikhwama esinemigoqo yokuma ekhombisa ukukhetha okukhethwa kukho.

Ake sibheke ukusetshenziswa okuvumelekile nokungavumelekile kokusetshenziselwa inetha:

ukusetshenziswa net e: * \\ iseva \ amafayela

Akuvumelekile: Isethi yokuqala ye-braces isho ukuthi ungacacisa i- devicename noma usebenzise uhlamvu lwe-wildcard * - awukwazi ukwenza kokubili. Noma ngabe ukusetshenziswa okungenasetshenziswa e: \\ iseva \ amafayela noma ukusetshenziswa kwenetha * \\ iseva \ amafayela kwakuyoba izindlela ezivumelekile zokwenza ukusetshenziswa kwenetha kuleli cala.

ukusetshenziswa kwenetha * \\ appsvr01 \ umthombo 1lovet0visitcanada / okuphikisanayo: cha

Kuyafaneleka: Ngisebenzise kahle izinketho eziningana kulokhu kusetshenziselwa ukusetshenziswa kwenetha, kufaka phakathi okukhethwa kukho okukodwa. Ngisebenzise i- * uma kudingeka ukuba ngikhethe phakathi kwayo futhi ngichaze i- devicename , ngichaze isabelo [ somthombo ] kuseva [ appsvr01 ], bese ukhetha ukucacisa i- { password } yalesi sabelo, 1lovet0visitcanada , esikhundleni sokuphoqelela ukusetshenziswa kwenetha ngiphakamise ngedwa { * }.

Ngiphinde nginqume ukungavumeli le drive entsha okwabelwana ngayo ukuthi ixhumane ngokuzenzakalelayo ngesikhathi esizayo ngiqala ikhompyutha yami [ / iphikisana: cha ].

ukusetshenziswa kwenetha / okuphikisanayo

Okungavumelekile: Kulesi sibonelo, ngakhetha ukusebenzisa inkinobho yokuzikhethela / ephikisanayo kodwa ngikhohliwe ukufaka ikholoni eceleni kwalo futhi ngikhohliwe ukukhetha phakathi kokubili okukhethwa kukho okudingekayo, yebo noma cha , phakathi kwama-braces. Ukusebenzisa ukusetshenziswa net / okuphikisanayo: yebo bekuyoba ukusetshenziswa okusemthethweni kokusetshenziswa kwenetha.
