Umyalelo we "gzip" yindlela eqhelekileyo yokucwangcisa iifayile ngaphakathi kweLuxux kwaye ngoko kukufanele ukwazi indlela yokucima iifayile usebenzisa le sixhobo.
Indlela yokuxinwa esetyenziswa ngu "gzip" yiLempel-Ziv (LZ77). Ngoku akubalulekanga ukuba uyazi le ngcaciso. Konke okufuneka ukwazi ukuba iifayile zincinci xa uxinezela nge "gzip" umyalelo.
Ngokungagqibekanga xa uxinzelela ifayile okanye ifolda usebenzisa umyalelo we "gzip" uza kuba negama elifanayo lefayile njengoko lenze ngaphambili kodwa ngoku kuya kuba nelula ".gz".
Kwezinye iimeko, akunakwenzeka ukuba kugcinwe igama elifanayo ngokukodwa ukuba igama lefayile lide lide. Kule meko, uya kuzama ukuyibeka.
Kule khokelo, ndiza kukubonisa indlela yokucwangcisa iifayile usebenzisa umyalelo we "gzip" kwaye ukwazisa ekutshintsheni okuqhelekileyo kusetyenziswa.
Indlela yokucima iFayile usebenzisa & # 34; gzip & # 34;
Indlela elula yokunciphisa ifayile enye usebenzisa i-gzip ukuqhuba umyalelo olandelayo:
gzip igama lefayile
Ngokomzekelo ukucinezela ifayile ebizwa ngokuthi "mydocument.odt" isebenze lo myalelo olandelayo:
gzip mydocument.odt
Ezinye iifayile zixinezela ngakumbi kunabanye. Ngokomzekelo amaxwebhu, iifayile zetekisi, imifanekiso ye-bitmap, ezinye iifomati zomsindo nevidiyo ezifana ne-WAV kunye ne-MPEG.
Ezinye iifayile zefayile ezinjengeemifanekiso ze- JPEG kunye neefayile ze-MP3 zomsindo azixineli kakuhle kwaye ifayile inokwenene ukwandisa ngobukhulu emva kokusebenzisa umyalelo we "gzip" ngokumelene nayo.
Isizathu salo kukuba iifayile ze-JPEG kunye neefayile ze- MP3 zomsindo sele zixinyiwe kwaye ngoko umyalelo we "gzip" wanezela nje kunokuba ucindezeleke.
Umyalelo we "gzip" uzakuzama ukunyanzelisa iifayile kunye neefolda rhoqo. Ngoko ke ukuba uzama kwaye uqine isixhumanisi esingokomqondiso asiyi kusebenza kwaye akunakulungele ukwenza njalo.
Indlela yokwenza iCompompress ifayile usebenzisa i & # 34; gzip & # 34; Myalelo
Ukuba unayo ifayile esele icinezele, ungasebenzisa lo myalelo olandelayo ukuyidibanisa.
gzip -d filename.gz
Ngokomzekelo, ukudibanisa i "mydocument.odt.gz" ifayile uza kusebenzisa umyalelo olandelayo:
gzip -d mydocument.odt.gz
Qinisekisa iFayile yokuxinwa
Ngamanye amaxesha ifayile ayikwazi ukuxinwa. Mhlawumbi uzama ukucindezela ifayile ebizwa ngokuthi "myfile1" kodwa sele sele ifayile efakwe ngokuthi "myfile1.gz". Kulo mzekelo, umyalelo we "gzip" awuyi kusebenza ngokuqhelekileyo.
Ukunyanzela umyalelo we "gzip" ukwenza izinto zayo usebenze nje umyalelo olandelayo:
gzip -f lefayile
Indlela Yokugcina Ifayile Engaxinzekanga
Ngokungagqibekanga xa ucindezela ifayile usebenzisa "gzip" umyalelo uphephe ngefayile entsha kunye nokwandiswa ".gz".
Ukuba ufuna ukucindezela i fayili kwaye ugcine ifayile yangaphambili kufuneka usebenze umyalelo olandelayo:
gzip -k lefayile
Umzekelo, ukuba uqhuba umyalelo olandelayo uza kugqiba ngefayile ebizwa ngokuthi "mydocument.odt" kunye ne "mydocument.odt.gz".
gzip -k yam cocument.odt
Fumana ezinye iiStats malunga Nendawo eninzi ogciniweyo
Inqaku elipheleleyo lokuqhafaza iifayile ngokuphathelele ukugcina isikhala sediski okanye ukunciphisa ubukhulu befayili ngaphambi kokuyithumela kwinethiwekhi.
Ngoko kuya kuba kuhle ukuba ubone ukuba yeyiphi indawo egciniweyo xa usebenzisa umyalelo we "gzip".
Umyalelo "we-gzip" unika uhlobo lweenombolo ezifunayo xa uhlola ukunyanzelwa komsebenzi.
Ukufumana uluhlu lweemanani luqhuba lo myalelo olandelayo:
gzip -l filename.gz
Ulwazi olubuyiselwe ngumyalelo ongentla apha lulandelayo:
- Ubukhulu obukhulu;
- Ubukhulu obungaphelelwanga;
- Ukulinganiswa njengepesenti;
- Igama lefayile elingapheliyo.
Ukucindezela zonke iifayile Kwifolda kunye neefayili
Ungaqinelela zonke iifayile kwifolda nakwifolda yayo ngokusebenzisa umyalelo olandelayo:
gzip -r ifayile yefayile
Oku akuyi kudala ifayile enye ebizwa ngokuba ngumnxeba wegama.gz. Endaweni yoko, uhamba ulawulo lwesakhiwo kwaye uqine iifayile nganye kwifom yefayile.
Ukuba ufuna ukucinezela isakhiwo sefolda njengefayile enye ulunge ngakumbi ekudaleni iifayile ze-tar uze ufake ifayili yentsimbi njengoko kuboniswe kule khokelo .
Indlela yokuvavanya ukuVunywa kweFayile ecinezelekileyo
Ukuba ufuna ukujonga ukuba ifayile isebenzayo, ungayisebenzisa umyalelo olandelayo:
gzip -t lefayile igama
Ukuba ifayile isebenzayo ayiyi kuba nemveliso.
Ungayitshintsha njani iNqanaba loXinzelelo
Unokuqhoqha ifayile ngeendlela ezahlukeneyo. Ngokomzekelo, unokwenza ukunyanzeliswa okuncinci okuza kusebenza ngokukhawuleza okanye unokuya kuqhutyelwa ukunyanzeliswa okuphezulu okunokwenza umsebenzi wokuthatha ixesha elide ukuqhuba.
Ukufumana ukunyanzela okuncinci kwinqanaba elikhawulezayo lisebenza lo myalelo olandelayo:
gzip -1 igama lefayile
Ukufumana ukunyanzeliswa okugqithiseleyo kwisantya esincinci kuqhuba umyalelo olandelayo:
igama legama le-gzip -9
Unokutshintsha isantya kunye nenqanaba lokunyanzelisa ngokukhetha amanani ahlukeneyo phakathi kwe-1 no-9.
Iifayile zeSiza zeSiza
Umyalelo we "gzip" awufanele usetyenziswe xa usebenza neefayile eziphambili zeefayile. Ungasebenzisa umyalelo we "zip" kwaye "unzip" umyalelo wokusingatha ezo fayile.
