Isingeniso
Umyalo wekati ku-Linux ikuvumela ukuba uhlanganise amafayela futhi ubonise okukhiphayo kumkhiqizo ojwayelekile, ezimweni eziningi lokhu yisikrini.
Enye yezinto ezisetshenziswa kakhulu ikati ukubonisa ifayela esibukweni futhi ukudala ifayela ngendiza futhi uvumele ukuhlela okuyisisekelo ngqo ekugcineni .
Indlela Yokudala Ifayela Ngokusebenzisa Ikati
Ukwakha ifayela usebenzisa umyalo wekhathi faka okulandelayo efasiteleni lokugcina:
ikati>
Ngokusobala, udinga ukufaka esikhundleni
Uma udala ifayela ngale ndlela i-cursor izoshiywa emgqeni omusha futhi ungaqala ukuthayipha.
Lena yindlela enhle yokuqala ifayela lombhalo noma ukudala ngokushesha ifayela lemininingwane yokuhlola njengefayili ekhishwe ama-comma noma ifayili ehlukanisiwe.
Ukuze uqede ukuhlela ifayela cindezela i-CTRL no-D.
Ungahlola ukuthi inqubo isebenza ngokuthayipha umyalo we-ls :
ls-k
Lokhu kubhala wonke amafayela kufolda yamanje futhi kufanele ubone ifayela lakho elisha futhi usayizi kufanele ube mkhulu kunezero.
Indlela Yokubonisa Ifayela Ngokusebenzisa Ikati
Umyalo wekati ungasetshenziswa ukubonisa ifayela esikrinini futhi. Konke okudingeka ukwenze ukuqeda okukhulu kunalokhu okulandelayo:
cat
Uma ifayela lide kakhulu-ke lizopheqa ngokushesha isikrini.
Ukubuka ikhasi lefayela ngekhasi sebenzisa umyalo owengeziwe :
I-cat
| Okuningi
Ngaphandle kwalokho, ungasebenzisa umyalo ongaphansi :
I-cat
| Ngaphansi
Ukuze uhlole lolu hlobo oluphuma kulo myalo olandelayo:
ikati / njll / passwd | Okuningi
Yiqiniso, ungase ukhohlwe nje ngekathi ngokuphelele bese uthayipha lokhu okulandelayo:
ngaphansi / njll / passwd
Indlela Yokubonisa Izinombolo Zombhalo
Kuzo zonke imigqa engenalutho kufayela ongasebenzisa umyalo olandelayo:
ikati -b
Uma kunemigqa engenazo izinhlamvu kuzo zonke ezingeke zibalwa. Uma ufuna ukukhombisa izinombolo kuzo zonke imigqa kungakhathaliseki ukuthi zingenalutho, thayipha umyalo olandelayo:
cat -n
Indlela Yokubonisa Ukuphela Komugqa Ngamunye
Ngezinye izikhathi lapho ukuxhuma abahleli befayela idatha kungase bahlangabezane nendaba ngoba kukhona izinhlamvu ezifihliwe ekugcineni kwemigqa engalindelekile njengezikhala. Lokhu kuvimbela abalandeli babo ukuba basebenze kahle.
Lesi yisinye sezizathu zokubonisa ukuphela komlingiswa wezinhlamvu ukuze ubone ukuthi kukhona yini izinhlamvu ezingenalutho.
Ukuze ubonise i-dollar njengophelo lomlingisi wezinhlamvu faka umyalo olandelayo:
cat -E
Njengesibonelo bheka umugqa olandelayo wombhalo
ikati lahlala phezu kombhede
Uma ugijima lokhu ngekati -E umyalo uzothola okukhiphayo okulandelayo:
ikati ihlale ematheni angu- $
Ukunciphisa Amaphuzu Angabonakali
Uma ubonisa okuqukethwe kwefayela usebenzisa umyalo wekhathi mhlawumbe awufuni ukubona uma kunezinto eziningi ezilandelanayo ezingenalutho.
Umyalo olandelayo ubonisa ukuthi unganciphisa kanjani ukukhipha ukuze ukuphinda imigqa engenalutho kukhishiwe.
Ukucacisa lokhu ngeke kufihlwe imigqa engacacile ngokuphelele kodwa uma unemigqa engu-4 engavaliwe elandelanayo izobonisa kuphela umugqa ongenalutho.
cat -s
Indlela Yokubonisa Amathebhu
Uma ubonisa ifayela elinamathebhu amathebhu ngeke uvame ukubona amathebhu.
Umyalo olandelayo ubonisa ^ Mina esikhundleni sethebhu eyenza kube lula ukubona ukuthi ukucabanga ifayela lakho aliqukethe ^ Nginalo noma kunjalo.
cat -T
Xhumanisa amafayela amaningi
Iphuzu elilodwa lekati yi-concatenation ngakho ungase ufise ukwazi ukuthi ungabonisa kanjani amafayela amaningi ngesikhathi esisodwa:
Ungakwazi ukufaka amafayela amaningi esikrinini ngomyalo olandelayo:
ikati
Uma ufuna ukunciphisa amafayela bese udala ifayela elisha sebenzisa umyalo olandelayo:
cat
>
Ukubonisa Amafayela E-Order Reverse
Ungabonisa ifayela ngokuhleleka ngokulandelana ngokusebenzisa umyalo olandelayo:
tac
Kulungile, ngakho-ke lokhu akusiyo umyalo wekati, ngumyalo we-tac kodwa ngokuyinhloko wenza into efanayo kodwa ngokuphindaphindiwe.
Isifingqo
Lokho kuhle kakhulu kumyalo wekati. Kuwusizo ekudaleni amafayili ngendiza kanye nokubonisa okukhipha kumafayela futhi-ke, ungayisebenzisa ukujoyina amafayela amaningi ndawonye.
