Uma ubheka ngokusebenzisa amafolda akho bese uthola amafayela nge-extension ye ".gz" kusho ukuthi baye bacindezelwa ngokusebenzisa umyalo we- "gzip" .
Umyalo we- "gzip" usebenzisa i-algorithm yokunciphisa i-Lempel-Ziv (ZZ77) ukunciphisa usayizi wamafayela afana namadokhumenti, izithombe, namathrekhi womsindo.
Yiqiniso, ngemuva kokucindezela ifayela usebenzisa i-"gzip" uzokwenza ngesinye isigaba ufuna ukuxilisa ifayela futhi.
Kulo mhlahlandlela, sizokubonisa ukuthi ungayenza kanjani i-decompress ifayela eliye lacindezelwa ngokusebenzisa umyalo we- "gzip".
Ama-Decompress Amafayela usebenzisa I & # 34; gzip & # 34; Umyalo
I-"gzip" iyala ngokwalo inikeza indlela yokudonsula amafayela nge-".gz" isandiso.
Ukuze udidekisile ifayela udinga ukusebenzisa inkinobho yedatha (-d) kanje:
gzip -d myfilename.gz
Ifayela lizoxilongwa futhi isandiso se- ".gz" sizosuswa.
I-Decompress A File usebenzisa i & # 34; gunzip & # 34; Umyalo
Nakuba ukusebenzisa umyalo we- "gzip" kusebenza ngokucacile kulula kakhulu ukukhumbuza nje ukusebenzisa "isibhamu" ukuze udidise ifayela njengoba kuboniswe kusibonelo esilandelayo:
gunzip myfilename.gz
Qinisekisa Ifayela Kuya Decompress
Ngezinye izikhathi umyalo "we-gunzip" unenkinga ngokudonswa kwefayela.
Isizathu esivamile sokuthi "isibhamu" esenqaba ukukhipha ifayela nge-decompress yilapho igama lefayela elizoshiywa ngemuva kokucindezeleka kufana nelinye elivele likhona.
Ngokwesibonelo, ake ucabange ukuthi unayo ifayela elibizwa ngokuthi "document1.doc.gz" futhi ufisa ukuliqedqa nge-command "gunzip". Manje ake ucabange ukuthi unefayela elibizwa ngokuthi "document1.doc" kufolda efanayo.
Uma ugijima umyalo olandelayo umlayezo uzovela ubonisa ukuthi ifayela selivele likhona futhi uzocelwa ukuthi uqinisekise isenzo.
gunzip document1.doc.gz
Ungakwazi, ngokuqinisekile, ukungena ku- "Y" ukwamukela ukuthi ifayela elikhona lizobhalwa phansi. Uma usebenzisa "isibhamu" njengengxenye yeskripthi, ngakho-ke ngeke ufune umlayezo ukuba uboniswe kumsebenzisi ngoba umisa iskripthi ukuba usebenze futhi udinga ukufaka.
Ungakwazi ukuphoqa umyalo we "gunzip" ukuze udideke ifayela ngokusebenzisa i-syntax elandelayo:
gunzip -f document1.doc.gz
Lokhu kuzokwandisa ifayela elikhona legama elifanayo futhi ngeke likukhuthaze ngenkathi wenza njalo. Ngakho-ke kufanele uqinisekise ukuthi usebenzisa ngokucophelela inkinobho ye-f (-f) ngokucophelela.
Indlela Yokugcina Yombili Ifayela Elicindezelekile Neliqediwe
Ngokuzenzakalelayo, umyalo we- "gunzip" uzokhipha ifayela nge-decompress futhi isandiso sizosuswa. Ngakho-ke ifayela elibizwa ngokuthi "myfile.gz" manje lizobizwa ngokuthi "i-myfile" futhi lizonwetshwa libe ngosayizi ogcwele.
Kungenzeka ukuthi ufuna ukudidliza ifayela kodwa futhi ugcine ikhophi yefayela elicindezelweyo.
Ungakwazi ukufeza lokhu ngokusebenzisa umyalo olandelayo:
gunzip -k myfile.gz
Manje uzoshiywa "nge-myfile" ne "myfile.gz".
Ukubonisa Okushicilelwe Okucindezelekile
Uma ifayela elicindezelweyo ifayela lemiyalezo bese ungabuka umbhalo ngaphakathi kwalo ngaphandle kokuthi ude decompress kuqala.
Ukuze wenze lokhu sebenzisa umyalo olandelayo:
gunzip -c myfile.gz
Umyalo ongenhla uzobonisa okuqukethwe kwe-myfile.gz ekukhipheni kokugcina.
Ulwazi Lokubonisa Ngefayela Elicindezelekile
Ungathola ulwazi olubanzi mayelana nefayela elicindezelweyo usebenzisa umyalo we "gunzip" kanje:
gunzip -l myfile.gz
Okukhipha komyalo ongenhla kubonisa amanani alandelayo:
- Usayizi ocindezelweyo
- Usayizi ongaxhunyiwe
- Ukulinganiswa
- Igama lokufaka elingavunyelwe
Isici esiwusizo kakhulu kulo myalo yilapho usebenza namafayela amakhulu noma idrayivu ephansi kwesikhala sedisk.
Cabanga ukuthi unesidrayivu esinama-gigabytes ayi-10 ngosayizi futhi ifayela elicindezelweyo yi-8 gigabytes. Uma ugijima ngempumputhe umyalo we "gunzip" khona-ke ungase uthole ukuthi umyalo uhluleka ngoba usayizi ongaxhunyiwe unama-gigabytes angu-15.
Ngokusebenzisa umyalo we "gunzip" nge-minus l (-l) ukushintsha ungacacisa ukuthi i-disk ukuthi udidliza ifayela ukuthi inesikhala esanele . Ungabona futhi igama lefayela elizosetshenziselwa uma ifayela lidonswa.
Ukunciphisa amafayela amaningi ngokuphindaphindiwe
Uma ufuna ukukhipha decompress wonke amafayela kufolda kanye nawo wonke amafayela kuwo wonke amafolda angezansi ukuthi ungasebenzisa umyalo olandelayo:
gunzip -r ifolda igama
Isibonelo, cabanga ukuthi unesakhiwo sefolda elandelayo namafayela:
- Amadokhumenti
- mydoc.gz
- mydoc1.gz
- Ama-Akhawunti
- spreadsheet1.gz
- spreadsheet2.gz
Ungakwazi ukudonsa zonke amafayela ngokusebenzisa umyalo olandelayo:
gunzip -r Amadokhumenti
Hlola ukuthi ngabe ifomu elicindezelekile livumelekile yini
Ungahlola ukuthi ifayela liye lacindezelwa ngokusebenzisa i- "gzip" ngokusebenzisa umyalo olandelayo:
gunzip -t filename.gz
Uma ifayela lingavumelekile uzothola umyalezo ngenye indlela, uzobuyiselwa kokufakwayo ngaphandle komlayezo.
Okufezeke Ngokuqondile Uma Uqedile Ifayela
Ngokuzenzakalelayo uma ugijima umyalo we "gunzip" ushiywe ngefayela elidonswe ngaphandle kwe-"gz" isandiso.
Uma uthola olunye ulwazi ungasebenzisa inkinobho ye-minus v (-v) ukuze ubonise ulwazi lwe-verbose :
gunzip -v filename.gz
Okukhiphayo kuzoba okufana nalokhu:
filename.gz: 20% - ithathwe esikhundleni segama lokufaka igama
Lokhu kukutshela igama lokuqamba le-compress, ukuthi lidonswe kangakanani futhi igama lokugcina.
