El dd yaziwa kahle ku-Linux. Kungumyalo oguquguqukayo, kepha bambalwa abaziyo ukuthi yini engayenza ngaphandle kokwenza isipele noma imininingwane yokupakisha. Ngakho-ke nginqume ukudala lesi sifundo esilula ngezibonelo ezithile zalokho umyalo we-dd ongakwenza. Zonke ziyizibonelo ezilula zezinto ezidinga ukwenziwa nsuku zonke.
Ngicabanga ukuthi usuyazi ukuthi yini i-dd umyalo womndeni we-UNIX futhi lokho kuvumela ukukopisha nokuguqula idatha ezingeni eliphansi, ngakho-ke inamandla amakhulu. Imvamisa yayisetshenziselwa ukwenza izipele noma amakhophi wesipele eminye imidiya yesitoreji, kepha futhi nokudlulisa imininingwane ethile, ukuguqula kusuka kolunye uhlobo lokufaka ikhodi kuye kolunye, njll. Yize kubonakala njengethuluzi lasendulo kakhulu, lisasetshenziswa nanamuhla futhi okuningi ...
Abanye izibonelo ezilula ezingokoqobo yalo myalo yile:
- Hlanganisa i-hard drive eyodwa uye kwenye ukuze i-sdb ikhophi eliqondile lokuqukethwe kwe-sda:
dd if=/dev/sda of=/dev/sdb
- Yenza ikhophi eyisipele yomkhombandlela, ifayili, noma ukwahlukanisa bese wenza isithombe (IMG, ISO, ...):
dd if=/dev/sda4 of=/home/backup/imagen.img
- Buyisela isipele sangaphambilini:
dd if=/home/backup/imagen.img of=/dev/sda4
- Dala i-ISO yediski ebonakalayo:
dd if=/dev/dvdrom of=/home/media/imagen.iso
- Susa idatha kusuka ku-hard drive ngokuyibhala ngaphezulu:
dd if=/dev/random of=/dev/sdb
- Dala ifayili ngosayizi othile, kulokhu ama-byte ayi-10, kepha ungakhetha inani olifunayo, futhi uma uguqula ukubala kube ngu-2, ngokwesibonelo, liyaliphinda kabili:
dd if=/dev/zero of=~/prueba bs=100 count=1
Ngiyethemba lesi sifundo sikusizile, njengoba ubona ukuthi silula, kepha singakusindisa ufake ezinye izinhlelo ezengeziwe. Isibonelo, uma ufuna ukwenza i-ISO ye-CD / DVD / BD, ungasebenzisa i-dd esikhundleni sokuba nesoftware ethile yalokho. Lokho futhi kungikhumbuza nge / dev / loop noma i-loop device, engakusiza futhi ukufaka i-ISO nokufinyelela kokuqukethwe kwayo ngaphandle kwesinye isoftware… Khumbula ukuthi ungabona eminye imininingwane nge-dd nge- "man dd". Inezinketho eziningi ongazithola zithakazelisa.
