Umyalo wesikhathi ngenye yemiyalo eyaziwa kakhulu ye-Linux kodwa ingasetshenziswa ukukhombisa ukuthi umyalo uthatha isikhathi eside kangakanani.
Lokhu kuyasiza uma unjiniyela futhi ufuna ukuhlola ukusebenza kohlelo lwakho noma iskriphthi.
Lo mhlahlandlela uzobhala uhlu olusha oluzosetshenziswa ngalo ngomyalo wesikhathi kanye nezincazelo zabo.
Indlela Yokusebenzisa I-Time Command
I-syntax yesikhathi somyalo kanje:
isikhathi
Isibonelo, ungasebenzisa umyalo we-ls ukuhlunga wonke amafayela kwifolda ngesakhiwo eside kanye nomyalo wesikhathi.
isikhathi ls -l
Imiphumela evela kumyalo wesikhathi iyoba kanje:
ama-0m0.177s wangempela
umsebenzisi 0m0.156s
ama-sym 0m0.020s
Izibalo ezikhonjisiwe zibonisa ukuthi isikhathi esiphezulu sithathwa ukugijima umyalo, isikhathi esasichithwa kumodi yomsebenzisi nesikhathi esichithwa kwimodi ye-kernel.
Uma unayo uhlelo olubhaliwe futhi ufuna ukusebenza emsebenzini ungawagijima kanye nomyalo wesikhathi ngokuphindaphindiwe bese uzama futhi uthuthukise izibalo.
Ngokuzenzakalelayo, okukhiphayo kuboniswa ekupheleni kohlelo kodwa mhlawumbe ufuna ukuthi umkhiqizo uhambe kufayili.
Ukukhipha ifomethi efayeleni sebenzisa i-syntax elandelayo:
isikhathi -o
isikhathi --output =
Zonke izinguquko zomyalo wesikhathi kufanele zicaciswe ngaphambi komyalo ofuna ukuwusebenzisa.
Uma wenza ukulungiswa kokusebenza ungase ufise ukufakela umkhiqizo kusukela ngesikhathi sokuya kufayela elifanayo ngokuphindaphindiwe ukuze ubone umkhuba.
Ukuze wenze kanjalo sebenzisa i-syntax elandelayo kunalokho:
isikhathi -a
isikhathi - phenduka
Ukufometha I-Output Of The Time Command
Ngokuzenzakalelayo okukhiphayo kanje:
ama-0m0.177s wangempela
umsebenzisi 0m0.156s
ama-sym 0m0.020s
Kunenombolo enkulu yokukhethwa kokufometha njengoba kuboniswe uhlu olulandelayo
- Amagama we-C - Igama nemilayezo asetshenziswayo
- D - Usayizi wesilinganiso sendawo yedatha engasetshenziswanga kuma-kilobytes
- E - Isikhathi esiphezulu kwifomethi yewashi
- F - Inombolo yamaphutha wekhasi
- I - Inombolo yezinhlelo zohlelo lwefayela ngenqubo
- K - Isilinganiso senkumbulo yokusetshenziswa kwenqubo yenqubo yama-kilobytes
- M - Isikhulu esiphezulu sendawo yokuhlala isamba senqubo ngesikhathi sokuphila kumaKlobytes
- O - Inombolo yezimiso zefayela lezinhlelo ngenqubo
- P - Amaphesenti we-CPU owathola umsebenzi
- R - Inombolo yamaphuzu amancane noma alulamekayo wekhasi
- S - Ingqikithi yenombolo yamasekhondi we-CPU asetshenziswe uhlelo kwimodi ye-kernel
- U - Ingqikithi yenombolo yamasekhondi we-CPU asetshenziswa imodi yomsebenzisi
- I-W - Inombolo yezikhathi inqubo eyasuswa ememori enkulu
- X - Inani elilinganiselwe lombhalo obiwe enkambisweni
- Isayizi sekhasi le-Z - Isistimu kuma-kilobytes
- c - Inani lezikhathi lapho inqubo ishintshiwe ngomongo
- e - Isikhathi sangempela esiphezulu esetshenziswa yinkqubo ngemizuzwana
- k - Inombolo yezibonakaliso ezithunyelwe kwinqubo
- p - Okulinganiselwe usayizi wokugcina we-unshared wenqubo kuma-kilobytes
- r - Inombolo yemilayezo etholekele etholwe yinqubo
- s - Inombolo yemilayezo eyisikwele ethunyelwe ngenqubo
- t - Isilinganiso sesilinganiso sokuhlala esiphezulu sezinqubo kuma-kilobytes
- w - Inombolo yesikhathi lapho inqubo ishintshiwe ngokwezifiso ngokuzithandela
- x - Isimo sokuphuma somyalo
Ungasebenzisa ukushintsha ukufometha kanje:
isikhathi -f "Isikhathi esiphezulu =% E, izinzuzo% I, Imiphumela% O"
Okukhipha umlayezo ongenhla kungaba into enjengale:
Isikhathi esiphelile = 0:01:00, Amaphesenti 2, Imiphumela 1
Ungaxuba futhi ufanise noshintsho njengoba kudingeka.
Uma ufuna ukwengeza umugqa omusha njengengxenye yefomathi yefomethi sebenzisa umlingiswa we-newline kanje:
isikhathi -f "Isikhathi esiphezulu =% E \ n Izimpendulo% I \ n Imiphumela" O "
Isifingqo
Ukuthola kabanzi mayelana nomyalo wesikhathi ufunde Ikhasi Lombhalo We-Linux ngokusebenzisa umyalo olandelayo:
indoda isikhathi
Ukushintsha kwefomethi akusebenzi ngokushesha ngaphakathi ku-Ubuntu. Udinga ukugijima umyalo kanje:
/ usr / bin / isikhathi
