Pamene simukufuna aliyense kuti awone mafayili omwe mumasula
Kusungunula ndi limodzi mwa malamulo anai a Linux omwe amamveka ofanana koma osagwirizana: kusambidwa, kupukuta, kuchotsa, ndi kuchotsa.
Mumagwiritsa ntchito poyera pamene mukufuna kuchotsa deta imodzi. Chidziwitso, chomwe inu mukuchizindikira, chikulembedwa ndi 1s ndi 0s kangapo, zomwe zimathetsa deta nthawi zonse. Izi ndi zosiyana ndi malamulo ena ofanana omwe amachotsa deta koma amasiyidwa nthawi zina.
Ndi lamulo lophwanyidwa, mukhoza kusonkhanitsa tinthu tating'onoting'ono ta maelo pamene mukufuna. Ndi njira yophweka yochotsera deta yomwe simukufuna aliyense kuti adziwe. Nthawizonse.
Syntax Yopsa
kudula [OPTIONS] FILE [...]Zosankha Pamene Mukugwiritsa Ntchito Shred Command
Gwiritsani ntchito lamulo la Shred kuti mulandire mafayilo mobwerezabwereza ndikupangitsa kuti zikhale zovuta kapena zosatheka kwa ngakhale mtengo wapatali wa hardware kapena mapulogalamu kuti mubwezeretse deta. Zomwe mungapeze zikuphatikizapo:
- -kusintha zilolezo kuti mulole kulemba ngati kuli kofunikira
- -n (iterations = N) imalemba nthawi N nthawi m'malo osasintha, omwe katatu
- -s (kukula = N) imatchula chiwerengero cha mayina ku kudetsedwa
- -u truncates ndi kuchotsa mafayilo atadutsa
- -v akuwonetsa verbose zokhudzana ndi kupita patsogolo
- -x sizithunzi zozungulira kuzungulira
- -z akuwonjezera kulembedwa kwina ndi zeros kubisala
- -chochotsa fayilo itatha pambuyo
Zitsanzo za Lamulo Lotsalira
Kuti mulowe mayina a maofesi omwe mukufuna kuwatsitsa, gwiritsani ntchito mtunduwu:
fred fileABC.text file2.doc file3.jpgNgati muwonjezerapo mwayi -u, maofayilo omwe alembedwawo amachotsedwa ndipo amachotsedwanso kuti amasule malo mu kompyuta yanu.

Kusungunuka kudalira pa lingaliro lofunika-kuti mawonekedwe a fayilo amalembetsa deta m'malo. Izi ndi zachikhalidwe, koma maofesi ena samakwaniritsa malingaliro awa. Zotsatirazi ndi zitsanzo za machitidwe a mafayilo omwe sanagwiritsidwe ntchito:
- Mapulogalamu owongolera kapena oyendetsa mapepala, monga omwe amaperekedwa ndi AIX ndi Solaris (ndi JFS, ReiserFS, XFS, ndi Ext3)
- Lembani mafayilo omwe alembetsa deta yopanda malire ndikupitirizabe ngakhale ena akulemba alephera, monga RAID -zithunzi zosinthika
- Fulogalamu yomwe imapanga zithunzithunzi, monga seva ya Network Appliance ya NFS
- Sungani maofesi omwe amapezeka m'malo osakhalitsa, monga makasitomala a NFS version 3
- Ndondomeko zamayendedwe
Ndiponso, ma dispulogalamu oyendetsa mafayilo ndi magalasi akutali angakhale ndi makopi a fayilo yomwe sungakhoze kuchotsedwa, ndipo izo zingalole kuti fayilo yofiira ipezedwe mtsogolo.
