Kamar yadda duk muka sani, masoyi dd [umarnin dd akan tsarin GNU / Linux] babban mutum ne idan ya zo ga yin isos, adana / rubuta MBR tsakanin sauran ayyuka. Amma yanzu da kyau yaya zan yi ISO da shi?

Abu mai sauƙi, kawai gudanar da waɗannan a cikin tashar ku:

dd if=/dev/cdrom of=/home/Install/Isos/debian-7.0.0-i386-CD-1.iso

if, ya zo daga "fayil din shigarwa", da of ya zo daga "Fayil na fitarwa”, Abin da a fili yake karantawa a cikin mutumin yana ɗaukar ɗan ƙaramin ruwan 'ya'yan itace zuwa lemun xD na lemu. A if an ƙayyade na'urar shigarwa, kuma a cikin of Za a ƙayyade hanyar fitarwa na fayil ɗinmu na ISO. Bayani mai mahimmancitare da cat yana yiwuwa a yi haka nan, wanda cat baya ɗaukarwa if ni of.

cat /dev/cdrom /home/Install/Isos/debian-7.0.0-i386-CD-1.iso

Don haka, tun da mun riga mun san wannan, bari mu ci gaba. Wani amfani kuma shine yin lalata da USB [Sodomize?], Ee, Na san yana da banƙyama, amma hey, ga waɗanda suka sayi sandunan ƙwaƙwalwar USB kuma suna da zafin rai don satar su, ma'ana, sayar da sandar USB na 4GB kuma tana da 128MB , wanda yake da matukar damuwa, zamu iya yin gwaji na asali:

Rubuta rubutu:
dd if=/dev/zero of=/dev/sdb1 bs=1M count=4096

Karatun gwaji:
dd if=/dev/sdb1 of=/dev/null bs=1M count=4096

Kwafa / karanta 4GB na sifili zuwa USB, duba cewa da gaske shine 4GB. Idan ya ƙare a baya kuma bai sanya adadin wanda aka saita ba, an yaudare ku xD.

Fadakarwa: duba sosai wanne ne USB din da ka jona, saboda zaka iya gayyatar rawar zuwa HDD [SATA] naka kuma ka rasa dukkan bayanan da kake dasu a ciki !!!

Sauran amfani daban-daban ...

Sanda rumbun kwamfutarka, don abubuwan IDE:
dd if=/dev/hda of=/dev/hdb bs=1M

don tafiyar SATA:
dd if=/dev/sda of=/dev/sdb bs=1M

Kwafa Babban Takardar Jagora:
dd if=/dev/hda of=mbr count=1 bs=512

Don dawo da MBR:
dd if=mbr of=/dev/hda

Irƙiri fayil ɗin musanya 1GB:
dd if=/dev/zero of=/boot/swap_space bs=1M count=1024
mkswap /boot/swap_space
swapon /boot/swap_space

[Kuma ga masu fashin kwamfuta xD, #ZOMG, masu fashin kwamfuta]

A 'yan kwanakin da suka gabata ina karanta hanyoyin da zan tsara HDD ɗinmu, ba tare da barin wata alama a kanta ba game da wani abu wanda ya kasance a baya, har ma da amfani da wasu manyan kayan neman bayanai na sirri, da kuma neman izza / gamsuwa. dd yana daga cikin hanyoyin da za'a iya maye gurbinsu.

Amma ta yaya zan iya yin wannan? Sauƙi:

Ciko rumbun kwamfutarka tare da sifili. Tare da bs = 1M, muna cewa duk karatun da rubuce-rubuce anyi su a bulogi 1 na megabyte. Hakanan zamu iya amfani / dev / bazuwar, amma yana ɗaukar duniya, yana samun shi matsayi na ƙarshe a cikin gwajin sharewar sauri: D.
