Uma ungafuni ukuthi ubani abone amafayela osusa
Ukushicilelwa kungomunye wezine imiyalo ye- Linux ezwakalayo efana kodwa ayifani: shred, sula, susa, futhi usule.
Usebenzisa ukukhishwa uma ufuna ukusula unomphela wedatha unomphela. Ulwazi, olukhombayo, lubhalwe nge-1s no-0s izikhathi eziningana, okususa unomphela idatha. Lokhu akufani neminye imiyalo efana nayo esula idatha kodwa ishiya itholakala ngaphansi kwezimo ezithile.
Ngomyalo okhishwe, ungafaka iqoqo elincane lamafayela noma kunini lapho ufuna khona. Kuyindlela elula yokususa idatha ongafuni ukuthi ubani akwazi ukuyihlanganisa. Ever.

shred [OPTIONS] FILE [...]Izinketho Uma usebenzisa i-Shred Command
Sebenzisa umyalo we-Shred ukuze ubhale phansi amafayela acacisiwe ngokuphindaphindiwe futhi wenze kube nzima noma akunakwenzeka ngisho nehadi elibizayo noma isofthiwe yokuthola idatha. Izinketho etholakalayo zihlanganisa:
- -i ushintshe izimvume zokuvumela ukubhala uma kudingeka
- -n (iterations = N) ibhala ngaphezulu izikhathi ezingu-N esikhundleni sokuzenzakalelayo, okuphindwe kathathu
- -s (isayizi = N) icacisa inani lezintandane kuya shred
- -u- truncates bese ususa amafayela ngemuva kokubhala ngaphezulu
- -v ibonisa ulwazi lwe-verbose mayelana nenqubekela phambili
- -x ayinayo ifayela elizungezile ubukhulu kuze kube ku-block elandelayo egcwele
- -z ineza ukubhalwa kokugcina nge-zero ukufihla ukukhwabanisa
- -ususa ifayela ngemuva kokubhala ngaphezulu
Izibonelo ze-Shred Command
Ukufaka amagama amafayela ngqo ofuna ukuwashisa, sebenzisa ifomethi elandelayo:
Ifayela elifakwe kufayela yefayelaABC.text2.doc3.jpgUma ungeza inketho -u, amafayela afakwe kuhlukile futhi asusiwe ukuze akhululeke isikhala kwikhompyutha yakho.

Ukushicilela kuncike ekucabangeni okubalulekile-ukuthi isistimu yefayili ibhala ngaphezulu kwedatha. Lokhu kungokweziko, kodwa ezinye izinhlelo zefayela aziwanelisi lokhu kucatshangwa. Okulandelayo yizibonelo zamafayela wefayela lapho ukukhishwa okungahambi kahle khona:
- Amasistimu wefayili ehleliwe noma ahanjisiwe, afana nalawo anikezwa i-AIX ne-Solaris (ne-JFS, i-ReiserFS, i-XFS, ne-Ext3)
- Amafayela wefayili abhala idatha evulekile futhi aqhubekele ngisho noma abanye babhala behluleka, njengama- RAID- asekelwe amafayela wefayela
- Amafayela wefayili enza ama-snapshots, njengeseva ye-Network Appliance yeNFS
- Izinhlelo zefayela ezifihla ezindaweni zesikhashana, njengamakhasimende we-NFS version 3
- Izinhlelo zefayela ezicindezelekile
Futhi, izipele zesistimu kanye nezibuko ezikude zingaqukatha amakhophi efayela elingenakususwa, futhi lokho kungavumela ifayela elifakiwe ukuthi litholwe kamuva.
