Ithimba le-Echo eLinux

Njengoba wazi, iningi lezenzo ku-Linux Operating System zenziwa nge-console. Abasebenzisi bazosebenzisa imiyalo ekhethekile ebhekele ukwenza izinqubo ezithile, futhi kusengaphambili izinketho ezicacisiwe zivumela ezazo izandla ukulawula amathuba angeziwe wezinto eziningi. Eminye yale miyalo i-Echo, futhi namhlanje sifuna ukutshela okuningi ngokuningiliziwe ngalesi sisetshenziswa, okuletha izibonelo eziningana zokusetshenziswa kwazo.

Sisebenzisa umyalo we-echo eLinux

Ithimba le-ECHO elibhekwayo namuhla linokubukeka okuqala nendawo okuyindawo ende - ukukhombisa umbhalo esikrinini. Kodwa-ke, lokhu akuphazamisi ukuthi kuvame ukusetshenziswa emibhalweni ehlukahlukene nangezinye izinhloso. Okulandelayo, siphakamisa kafushane nge-syntax yalesi sisetshenziswa futhi sihlukanise izibonelo ezithandwa kakhulu futhi ezilula zokufaka kwazo kwikhonsoli ejwayelekile.

I-Echo Syntax

Cishe wonke amaqembu, ngaphezu komsebenzi oyinhloko, angenza nezinye izinto ezihambisana nezimpikiswano ezibekiwe. U-Echo akazange ahlukile kulokhu, kepha, ngenxa yokulula kwezinketho ezithuthukile uqobo, akukho okuningi. Ake sikubheke ngokwengeziwe ngakunye kwawo, kepha okokuqala unake ukubuka okujwayelekile komugqa: Izinketho ze-Echo + + + Izinketho.

• -N - ngeke ibonise ukudluliswa komugqa;
• -E - ebhekele ukufakwa kokulandelana kokuphunyuka;
• -E - Ikhubaza ukuhunyushwa kokulandelana kokuphunyuka.

Siphinde saphawula nokuthi ukulandelana kokuphunyuka kuyizinketho ze-Universal ezethulwe ngohlobo lwezimpawu. Ngayinye yazo inenani eliqinisekile, futhi uma unika amandla ukutolika lapho usebenzisa umyalo we-echo, ungasebenzisa izimpikiswano ezinjalo:

• / C - ubhekele ukususa ukudluliswa kwentambo;
• / T - Ibonisa ithebhu evundlile;
• / V - kwakha ithebhu mpo;
• / B - Ususa uphawu lwangaphambilini entanjeni;
• / n - kufaka phakathi ukudluliswa kwentambo kulokho okusha;
• / R - Ibuyisa inqola ekuqaleni komugqa.

Siphinda futhi, sicacisa izinketho ezingenhla zitholakala ukungena kuphela kulezo zimo lapho uqalise ekuqaleni khona-ibhendi. Uma kunesidingo, ngamunye walolu phawu angathuthukiswa ngemuva kwamanye amagama okufaka amagama esizokhombisa kule miyalelo elandelayo.

Isiphetho sentambo elula

Njengoba kushiwo ngaphambili, inhloso eyinhloko yomyalo we-echo ukukhishwa kwesikrini sentambo. Kukule ngalokhu esifuna ukukhuluma ngokuqhubekayo, kuhlolisise izenzo ezimbalwa ezilula ezizosiza ukuqonda kahle ukuthi zonke izinto ezikhethekile zisebenza kanjani.

1. Gijimani ikhonsoli evumelana nawe, ngokwesibonelo, ngemenyu yohlelo lokusebenza noma ngokucindezela ukhiye oshisayo we-Ctrl + Alt + T Icushiwe ngokucindezela ukhiye we-Enter.



2. Njengoba ukwazi ukubona, emgqeni omusha, amagama asanda kufakwa ngendlela efanayo yavela.



3. Uma ufaka inketho \ b ngaphambi kwegama ngalinye, kuzosulwa umlingiswa owedlule, okusho ukuthi umphumela uzoboniswa ngaphandle kwezikhala, uma nje sinombono wokuqala we-Echo-BlinUX ".



4. Sibeka inketho ecacisiwe kuwo wonke amagama, ngakho-ke umphumela wawufanelekile.



5. Manje ake sinake ipharamitha \ n. Njengoba usuvele wazi, kusebenze ukudluliswa kwentambo, uma kungakhonjiswanga ekuqaleni.



6. Sibonise \ n Ngamafuphi ngemuva kokuqala, ngakho-ke, ngamunye wabo azokhonjiswa emgqeni omusha.



7. Siphendukela kuthebhu esetshenziselwa ukuvumelanisa umbhalo. Uzobhalisa ngokwanele ezindaweni ezidingekayo ukuze uzuze umphumela oyifunayo.



8. Njengoba kungabonakala, ngegama lokuqala, ukutholwa kwasetshenziswa kabili. Cabanga ngalokhu lapho kuboniswa imigqa.



9. Ngokwengeziwe, akukho lutho oluphazamisa ukucacisa izinketho eziningana ngokulandelana, ukubuka imithetho yokufaka.



10. Isibonelo, esikrinini esingezansi ubona umphumela wokukhishwa ngokudluliselwa kanye nethebhu ngasikhathi sinye.



11. Njengesibonelo sokugcina, thatha / v. Le ngxabano idala ithebhu mpo.



12. Ngenxa yalokhu, igama ngalinye litholakala emgqeni omusha nangendlela yezinyathelo.

Manje uyazi ukuthi umyalo we-echo uyakwazi ukubonisa imigqa ecacisiwe kunoma yiliphi uhlobo olungasetshenziswa ngokucacisa izinketho ezifanele. Asiye kwamanye amapharamitha ukuze uqonde ukuthi yimuphi kubo okufanele uhlanganise ngefomethi efanele.

Ukukhishwa kwamanani ahlukahlukene

Cishe yonke imibhalo, kusetshenziswa izinto ezithile ezihlukile lapho inani kusengaphambili. Uma sikhuluma ngomsebenzi we-echo, khona-ke uyakwazi ukukhipha incazelo. Sizocubungula lesi sibonelo kusosikhathi esisodwa esibulalayo ngaphandle kwendalo yangaphambi kweskripthi uqobo. Lokhu kusho ukuthi lapho uqala kabusha ikhonsoli, amanani azosuswa.

1. Okokuqala, ukudala ukuguquguquka kwesivivinyo ngokufaka ukuthekelisa i = ama-Lumpics, lapho nginguLama lokuhlukahluka, futhi ama-Lucics anenani lawo.



2. Sebenzisa i-Echo $ I ukukhombisa inani lokuguquguquka okukhethiwe kulayini olandelayo.



3. Njengoba ubona, konke kuboniswa kahle.



4. Dala okunye ukuhlukahluka ngokuthumela ngaphandle l = linux.



5. Sethula umyalo wecala u-Echo $ i Site $ L.



6. Manje uyazi ukuthi i-echo ikhuluma ngokukhishwa kwezinto ezimbili noma ngaphezulu ngefomethi yomugqa owodwa.

Ezimweni eziningi, lokhu kukhishwa kwezindlela eziguquguqukayo kusetshenziswa kuphela lapho ukubhala imibhalo, noma kunjalo, umsebenzi onjalo ungaba wusizo uma kuhlelwa ukukhiqiza inqwaba yokuncika okufanayo ngenani elilodwa.

Ukunikeza imibala intambo

Uma usebenzisa ngenkuthalo i-Console, uyazi ukuthi igama ngalinye lingathatha noma yimuphi umbala otholakalayo lapha, hhayi nje omhlophe noma omnyama (ngokuya ngesihloko esithi "ukuphela" ukugcina "). I-ECHO ibuye ikuvumele ukuthi upende imigqa, futhi unesibopho salezi zingxabano ezinjalo:

• \ 0 12m [mnyama;
• \ 033 [31M - obomvu;
• \ 0 123 [32m - luhlaza;
• \ 0 123 [33m - ophuzi;
• \ 0 123 [34m - luhlaza okwesibhakabhaka;
• \ 0 123 [35m - onsomi;
• \ 0 06m - luhlaza okwesibhakabhaka;
• \ 033 [37m - grey.

Kunezinye izimpikiswano eziningi ezikuvumela ukuthi ushintshe umbala wesizinda esibhaliwe. Kubukeka njengohlu olufana, kepha kunomehluko ngamanani:

• \ 033 [40m - mnyama;
• \ 033 [41m - obomvu;
• \ 0 123 [42m - luhlaza;
• \ 033 [43m - ophuzi;
• \ 0 123 [44m - luhlaza okwesibhakabhaka;
• \ 0 123 [45m - onsomi;
• \ 033 [46m - luhlaza okwesibhakabhaka;
• \ 033 [47m - grey;
• \ 033 [0m - Setha kabusha wonke amanani esifundazweni esizenzakalelayo.

Njengoba usuvele uqonda, lezi zingxabano kuzodingeka zisetshenziswe emgqeni ngamunye uma kunesidingo. Kubukeka njengesakhiwo esifanayo ngale ndlela elandelayo: echo -e "\ 03mmumpics \ 033 [46msiSite \ 033 [41MLux".

Isibonelo esingenhla sasinemibala yesizinda esinemibala ngombala we-orange, futhi izizinda zemibala ehlukene zangenziwa kusebenze "kusayithi" kanye ne- "Linux". Uyakubona lokhu ku-skrini ngaphansi komyalo ofakiwe.

Izinhlamvu ezikhethekile ze-bash

Umsebenzi we-ECHO Command kuphela endaweni ye-Bash, ngokulandelana, kufanele agcine izinketho ezijwayelekile zale ndawo. Ezimweni eziningi, banesibopho sokuhlunga amafayela nokukhishwa kwezinto zendawo yamanje.

1. Faka i-Echo * esibulalayo ukukhombisa okuqukethwe kufolda yamanje.



2. Umugqa olandelayo uzovela uhlu lwezinkomba kanye nezinto ezingenayo. Kuzoba yintambo ejwayelekile ngaphandle kokubhalisa. Kodwa-ke, manje usuvele uyazi ukuthi ingashintshwa ngesisekelo sezibonelo ezingenhla.



3. Cacisa i-Echo * .txt uma ufuna ukubonisa kuphela izinto zefomethi ebekiwe. Faka esikhundleni .txt kwenye inketho edingekayo.



4. Ekugcineni, siphawula ukuthi i-ECHO futhi yenza ukuhlela amafayela wokucushwa, okwenziwa ngokulandelayo: Echo 1> / Proc / ASS / IP_ASTWAY. 1 - I-String for application, A / Proc / Sys / Net / IPv4 / IP_Iforward - Indlela eya entweni oyifunayo.

Njengengxenye yezinto ezibonakalayo zanamuhla, sisebenzelana ne-Echo ohlelweni lokusebenza lweLinux. Uma unesifiso esihlokweni sokuxhumana namaqembu athandwayo, ngaphezu kwalokho, sincoma ukufunda i-athikili ngalesi sihloko kwiwebhusayithi yethu, ngenkathi ihamba ngaphansi kwezixhumanisi ezingezansi.
