El dd yaziwa kakuhle kwiLinux. Ngumyalelo oguquguqukayo, kodwa bambalwa abayaziyo inokwenza ngaphandle kokuxhasa okanye ukupakisha ulwazi. Kungenxa yoko le nto ndigqibe kwelokuba ndenze esi sifundo silula kunye neminye imizekelo ebonakalayo enokwenziwa ngulo myalelo we-dd. Yonke iyimizekelo elula yezinto ekufuneka yenziwe yonke imihla.
Ewe ndicinga ukuba sele uyazi ukuba yintoni i-dd Umyalelo wosapho we-UNIX kwaye oko kuvumela ukukopa kunye nokuguqula idatha kwinqanaba elisezantsi, ke kunamandla amakhulu. Yayisetyenziswa ngokubanzi ukwenza i-backups okanye iikopi zokulondolozwa kwemithombo ethile yosasazo, kodwa kunye nokudlulisa idatha ethile, ukuguqula ukusuka kuhlobo olunye lokufaka iikhowudi ukuya kolunye, njl. Nangona kubonakala ngathi sisixhobo esidala kakhulu, isasetyenziswa nanamhlanje kwaye kuninzi ...
Abanye imizekelo elula esebenzayo yalo myalelo zezi:
- Cwangcisa enye i-hard drive kwenye ukuze i-sdb ikopi ngqo yomxholo we-sda:
dd if=/dev/sda of=/dev/sdb
- Yenza ikopi yogcino yolawulo, ifayile, okanye isahlulelo kwaye wenze umfanekiso (IMG, ISO, ...):
dd if=/dev/sda4 of=/home/backup/imagen.img
- Buyisela ugcino lwangaphambili:
dd if=/home/backup/imagen.img of=/dev/sda4
- Yenza i-ISO yediski ebonakalayo:
dd if=/dev/dvdrom of=/home/media/imagen.iso
- Cima idatha kwi-hard drive ngokuyibhala ngaphezulu:
dd if=/dev/random of=/dev/sdb
- Yenza ifayile enobungakanani obuthile, kule meko zii-byte ezili-10, kodwa ungakhetha isixa osifunayo, kwaye ukuba uguqula ukubala ukuya ku-2, umzekelo, iyayiphinda-phinda:
dd if=/dev/zero of=~/prueba bs=100 count=1
Ndiyathemba ukuba le khosi ikuncedile, njengoko ubona kulula kakhulu, kodwa inokukugcina ufake ezinye iinkqubo ezongezelelweyo. Umzekelo, ukuba ufuna ukwenza i-ISO yeCD / DVD / BD, ungasebenzisa dd endaweni yokuba nesoftware ethile. Oko kuyandikhumbuza nge / dev / loop okanye isixhobo esitshixwayo, esinokukunceda ukunyusa i-ISO kunye nokufikelela kumxholo wayo ngaphandle kwesoftware eyongezelelweyo… Khumbula ukuba ungabona ulwazi oluthe kratya malunga ne-dd nge "man dd". Inokhetho oluninzi onokulufumana unomdla.
