Chokwadi kanopfuura kamwe chete zvakaitika kwauri kuti netsaona ubvise imwe data, kana iwe waifunga kuti zvaive zvisingachadiwe uye zvobva zvazoitika kuti gare gare iwe unofanirwa kudzosera iro ruzivo uye kuti nekuda kwechimwe chirongwa kana imwe kodhi iwe unogona kupora; Asi ko kana iwe uchida kudzima zvachose data? Sezvo paine maturusi ekudzoreredza isu tinogona zvakare kuwana ekuparadza maturusi, akadai Kubvarura
Ichi chishandiso chinouya mukati mehomwe coreutils iyo yakagara yakaiswa-mukati mukati mekuparadzirwa kweLinux, iyi coreutils package inosanganisira akateedzana ezvishandiso ekutanga emutsetse wekuraira, pakati payo iri kubvarura, hachisi chinhu chinopfuura chinhu chinoshamisira kuve chiri nyore kushandisa uye pamusoro pezvese zvinobatika kuparadza zvese zvatinoda (kana izvo zvatisingachadi) sekureva kwezita racho.
Iko kushanda kwe Kubvarura ndeyekuti inonyanya kunyora iyo faira kana dhata ratinoratidzira kanoverengeka (25 nekukasira) izvi zvinoitwa uchishandisa akasiyana mameseji zvirongwa, kushandura zvese izvo zvine yekutanga faira zvine, kuita chimwe chakasiyana zvachose zvemukati zvine ruzivo rusina maturo.
Kune vashandisi vasingazive, vanogona kuongorora zvese izvo chishandiso ichi chinotibvumidza nekutarisa pa murume akacheka.
Mushure meizvi ngatiendei kuchikamu chinoshanda; Ngatitangei nemuenzaniso wekushandisa kwayo, kutanga kuti tione kuti chii nezvacho isu tichatora rakaomarara diski kana chimwe chikamu: dai taive nechikamu chakadzorwa nehukuru, tichishandisa rairo lsblk isu tinobva tatsvaga chikamu chatiri kuda, nemurairo umount yaizobviswa uyezve ne kubvarura isu tichakupa wongororo nenguva:
shred -vzn 0 / dev / sda1
Nemutsara wapfuura tinenge tiri kubvisa data rese riri muchikamu "sda1" uye nemamwe maparameter akadai se "v" ayo anotiratidza kufambira mberi kwekushanda, "z" izvo zvinotibatsira kuvhara kuparadzwa nekunyora pamusoro nemazero kumagumo uye "n" inoteverwa ne zero, zvinoreva kuti maitiro anoitwa kamwe chete pasina kudzokorora; kunyanya kuita kwacho kuchidzokororwa, iko kubviswa kwacho kuchinyanya kushanda, ko kana iwe uchifanira kuchengeta mupfungwa kana uchishandisa Shred ndeyekuti izvi inzira inononoka, kunyanya kana tichizoshandisa pamadhisiki ehukuru hwakakura; Muenzaniso iwoyo unovaratidzira unokurudzirwa kuti ushandiswe nemushandisi asiri nyanzvi kana mushandisi wakajairika.
Kana isu tichizodzima faira zvingave zviri nyore uye nekukurumidza zvakanyanya:
shred -u / nzira / faira
Sarudzo "u" ine basa rekudzima iyo data. Nekudaro, kana tikasangana nefaira rakakura kwazvo, tinogona kushandisa nhanho imwechete, tinongowedzera iyo paramende uye tinoiudza kuti idzokore maitiro katatu.
shred -ubzn 2 / nzira / faira
Chikamu icho isu chatinofanira kungwarira chiri mukati tinoshandisa kupi shred, nekuti inogona kusashanda nemagadzirirwo ekuchengetedza kana neese mafaera masystem.
Zvakanaka, chinhu chega chisingandikwane ndechekuti ndinofunga kuti pane akaomarara madhiraivhi nechinyorwa chiri nyore hazvitokwanisika kudzoreredza chero data, hazvidi kuti uzviite ka25. Zvichida yakagadzirirwa kuitirwa chero rudzi rwechigadzirwa, handizive kana tepi ichida kunyorwa kakawanda kuti zvidzivirire kupora.
Ini ndinoshamisika kana iyi data yekunyora ichidikanwa zvakare pane SSD yakaoma dhiraivha
SSDs chinhu chakaparadzaniswa nekuda kwenzira yavo yekunyora, iyo inogara ichidzivirira kunyora panzvimbo imwechete. Saka ndatsvaga ndikatsanangura nyaya yacho zvishoma apa:
