Umyalo we "gzip" kuyindlela evamile yokucindezela amafayela ngaphakathi kweLinux ngakho-ke kufanelekile ukwazi ukuthi ungacindezela kanjani amafayela usebenzisa le thuluzi.
Indlela yokucindezela esetshenziswa "i-gzip" yiLempel-Ziv (LZ77). Manje akubalulekile ukuthi wazi lolu lwazi. Konke okudingeka ukwazi ukuthi amafayela athola amancane uma uwacindezela ngomyalo we- "gzip".
Ngokuzenzakalelayo uma ucindezela ifayela noma ifolda usebenzisa umyalo we- "gzip" izoba negama elifanayo lefayela njengoba lenze ngaphambilini kepha manje lizoba nesandiso ".gz".
Kwezinye izimo, akunakwenzeka ukugcina igama elifanayo ikakhulukazi uma igama lefayela lide kakhulu. Kulezi zimo, kuzama ukuyiqeda.
Kulo mhlahlandlela, ngizokubonisa indlela yokucindezela amafayela usebenzisa umyalo we- "gzip" futhi ukwethule ekushintsheni okuvame ukusetshenziswa.
Indlela Yokucindezela Ifayela Ngokusebenzisa & # 34; gzip & # 34;
Indlela elula yokucindezela ifayela elilodwa usebenzisa i-gzip ukuqhuba umyalo olandelayo:
gzip igama lefayela
Ngokwesibonelo, ukucindezela ifayela elibizwa ngokuthi "mydocument.odt" ligijima umyalo olandelayo:
gzip mydocument.odt
Amanye amafayela acindezela kangcono kunabanye. Ngokwesibonelo amadokhumenti, amafayela wombhalo, izithombe ze-bitmap, amafomethi athile alalelwayo namavidiyo afana ne-WAV ne-MPEG ngokucindezela kahle.
Ezinye izinhlobo zefayela njengezithombe ze- JPEG namafayela e-MP3 alalelwayo azicindezeli nhlobo futhi ifayela lingase landa ngempela usayizi ngemuva kokusebenzisa umyalo we- "gzip" ngokumelene nayo.
Isizathu salokhu ukuthi imifanekiso ye-JPEG namafayela e- MP3 alalelwayo kakade kucindezelwe futhi ngakho-ke umyalo we- "gzip" uvele ungeze kukho kunokucindezela.
Umyalo we "gzip" uzozama ukucindezela amafayela namafolda avamile. Ngakho-ke uma uzama futhi ucindezela isixhumanisi esingokomfanekiso ngeke sisebenze futhi akunakwenzeka ngempela ukwenza kanjalo.
Indlela Yokunqamula I-Decompress A File Ngokusebenzisa i- & # 34; gzip & # 34; Umyalo
Uma unefayela elivele licindezelekile ungasebenzisa umyalo olandelayo ukuyikhipha.
gzip -d filename.gz
Ngokwesibonelo, ukuze udidekisile ifayela elithi "mydocument.odt.gz" uzosebenzisa umyalo olandelayo:
gzip -d mydocument.odt.gz
Qinisekisa Ifayela Ukuze Ucindezeleke
Ngezinye izikhathi ifayela alikwazi ukucindezelwa. Mhlawumbe uzama ukunciphisa ifayela elibizwa ngokuthi "myfile1" kodwa kakade ifayela elibizwa ngokuthi "myfile1.gz". Kulokhu, umyalo we- "gzip" ngeke usebenze.
Ukuphoqa umyalo we- "gzip" ukwenza izinto zawo uvele ugijime umyalo olandelayo:
gzip -f igama lefayela
Indlela Yokugcina Ifayela Le-Uncompressed
Ngokuzenzakalelayo uma ucindezela ifayela usebenzisa umyalo we- "gzip" ugcina ngefayela elisha nesandiso ".gz".
Uma ufuna ukucindezela ifayela bese ugcina ifayela langempela kufanele usebenze umyalo olandelayo:
gzip -k igama lefayela
Isibonelo, uma uqhuba umyalo olandelayo uzophela ngefayela elibizwa ngokuthi "mydocument.odt" nelithi "mydocument.odt.gz".
gzip -k i-mydocument.odt
Thola ezinye izitatimende Mayelana Nengakanani Isikhala Esilondolozile
Iphuzu eliphelele lokucindezela amafayela liphathelene nokugcina isikhala sediski noma ukunciphisa usayizi wefayela ngaphambi kokuyithumela ngenethiwekhi.
Ngakho-ke kungaba kuhle ukubona ukuthi kungakanani isikhala esilondoloziwe uma usebenzisa umyalo we- "gzip".
Umyalo we- "gzip" unikeza uhlobo lwezibalo ozidingayo uma uhlola ukusebenza kokucindezela.
Ukuze uthole uhlu lwezibalo ugijime umyalo olandelayo:
gzip -l filename.gz
Ukwaziswa okubuyiselwe ngumyalo ongenhla kanje:
- Usayizi ocindezelweyo;
- Isayizi engaxhunyiwe;
- Ukulinganisa njengephesenti;
- Igama lokufaka elingagxiliwe.
Ukucindezela Zonke Ifayela KuFolda Nezingaphansi
Ungacindezela zonke ifayela kwifolda kanye nezigcawu zalo ngokusebenzisa umyalo olandelayo:
gzip -r ifolda lomsebenzisi
Lokhu akudali ifayela elilodwa elibizwa ngokuthi ifoldaname.gz. Esikhundleni salokho, idlula isakhiwo somqondisi futhi igcizelela ifayela ngalinye kuleso sakhiwo sefolda.
Uma ufuna ukuncindezela isakhiwo sefolda njengefayela elilodwa ungcono ekudaleni ifayela le-tar bese ufaka ifayela le-tar njengoba kuboniswe kulolu mhlahlandlela .
Indlela Yokuhlola Ukuqinisekiswa Kwefayela Elicindezelekile
Uma ufuna ukuhlola ukuthi ifayela livumelekile, ungasebenzisa umyalo olandelayo:
gzip -t igama lefayela
Uma ifayela livumelekile ngeke kube khona okukhiphayo.
Indlela Yokushintsha Izinga Lokucindezela
Ungacindezela ifayela ngezindlela ezahlukene. Isibonelo, ungahamba ngokunciphisa okuncane okuzosebenza ngokushesha noma ungahamba ngokucindezela okuphezulu okuphethe i-tradeoff yokuthatha isikhathi eside ukuqhuba.
Ukuze uthole ukucindezelwa okungenani ngesivinini esheshayo sebenzisa umyalo olandelayo:
gzip -1 igama lefayela
Ukuze uthole ukucindezeleka okuphezulu ngesikhathi esisheshayo phatha umyalo olandelayo:
gzip -9 igama lefayela
Ungashintsha izinga lejubane nokucindezela ngokukhetha izinombolo ezahlukene phakathi kuka-1 no-9.
Amafayili e-Standard Standard
Umyalo we- "gzip" akufanele usetshenziswe uma usebenza namafayela e-zip evamile. Ungasebenzisa umyalo we "zip" futhi "unzip" wokuphatha lawo mafayela.
