Xa ungafuni nabani na ukubona iifayile ozicimayo
Ukushicilela ngenye yeemithetho ezine ze- Linux ezivakalayo ezifanayo kodwa ezingafaniyo: shred, sula, susa, kwaye ususe.
Usebenzisa ukucima xa ufuna ukucima iqela elilodwa leenkcukacha ngokusisigxina. Ingcaciso, oyichongayo, ibhalwe ngaphezulu nge-1 kunye ne-0 iihlandlo eziliqela, ezitshintsha ngokusisigxina idatha. Oku akufani neminye imiyalelo efanayo ekhupha idatha kodwa yishiye ithoxiswe phantsi kweemeko ezithile.
Ngomyalelo oqingqiweyo, unokwenza iqoqo encinci yeefayile xa ufuna. Yindlela elula yokucima idatha ongafuni ukuba nabani na umntu abe nako ukukwazi ukungena. Namaxesha onke.

ukutyhila [IMISEBENZI] FILE [...]Izinketho Xa usebenzisa i-Shred Command
Sebenzisa umyalelo we-Shred ukuba ubhale ngaphezulu iifayile ezicacisiweyo ngokuphindaphindiweyo kwaye wenze kube nzima okanye akunakwenzeka kwi-hardware okanye i-software ebiza kakhulu ukubuyisela idatha. Izinketho ezikhoyo ziquka:
- -u tshintsho iimvume zokuvumela ukubhala xa kuyimfuneko
- -n (iterations = N) i-overwrites amaxesha ama-N endaweni ye-default, ephindwe kathathu
- -s (ubukhulu = N) icacisa inani leebhasi ukuba kuhlutha
- -i- truncates kwaye ususa iifayile emva kokubhaliweyo
- -v ibonisa ulwazi lwe verbose malunga nenkqubela phambili
- -x ayifaki iifayile ezijikelezayo ukuya kwi-block elandelayo epheleleyo
- -n yongeza i-final overwrite nge-zeros ukufihla ukutshisa
- -uyakususa ifayile emva kokugqithisa
Imizekelo yeSilawuli Sokusila
Ukufaka amagama eefayili ngqo ofuna ukuyichitha, sebenzisa ifomathi elandelayo:
fayile ifayileABC.text file2.doc file3.jpgUkuba ungeze ukhetho -u, iifayile ezifakwe apha zifakwe kunye kwaye zisusiwe ukukhulula isikhala kwikhompyutha yakho.

I-Shred ithembele kwi-assumption ebalulekileyo-ukuba inkqubo yefayili ibeka ngaphezulu idatha kwindawo. Le yindabuko, kodwa ezinye iifayile zefayili aziwanelisi le ngcamango. Ezi zilandelayo zemizekelo yeefayile zefayile apho i-shred ingasebenzi:
- Iinkqubo zefayili ezidibeneyo okanye ezihamba ngefayile, njengalezo zibonelelwa nge-AIX no-Solaris (kunye ne-JFS, i-ReiserFS, i-XFS, ne-Ext3)
- Iifayile zefayile ezibhala idatha ehlukileyo kwaye ziqhubeke nokuba ngaba abanye babhala behluleka, njenge- RAID- iifayile zeefayile ezisezantsi
- Iifayile zeefayile ezenza i-snapshots, njengeseva yeNFS yeNethiwekhi ye-Appliance
- Iifayile zefayile ezifihlakeleyo kwiindawo zesikhashana, njengabaxhasi be-NFS version 3
- Iinkqubo zefayile ezixinzelelweyo
Kwakhona, ifayile yefayile kunye nezibuko ezikude zingaqukatha ikopi yefayili engenakususwa, kwaye loo nto inokuvumela ifayile edibeneyo ukuba ibuyiswe kamva.
