DESCRIPTION
bzip2 imaphatikiza mafayilo pogwiritsa ntchito Burrows-Wheeler kukonza ndondomeko yolemba malemba, ndi Huffman kukopera. Kuponderezana kumakhala kosavuta kwambiri kusiyana ndi zomwe zinapangidwa ndi compressors zowonjezereka za LZ77 / LZ78, ndipo zikuyendera momwe polojekiti ya PPM imagwirira ntchito.
Mndandanda wa mndandanda wa malamulo ndi mwadala mofanana kwambiri ndi wa GNU gzip, koma sali ofanana.
bzip2 amayembekeza mndandanda wa maina a fayilo kuti azitsogoleredwa ndi mbendera za mzere. Fayilo iliyonse imalowetsedweratu ndi zolembedwera zokha, zomwe zimatchedwa "original_name.bz2". Fayilo iliyonse yosinthidwa ili ndi tsiku lomwelo losinthidwa, zovomerezeka, ndipo, ngati n'kotheka, umwini monga choyambirira choyambirira, kotero kuti izi zikhoza kubwezeretsedwa moyenera pa nthawi yachisokonezo. Kugwiritsa ntchito fayilo ndizosafunika m'lingaliro lakuti palibe njira yopezera maina oyambirira mafayilo, zilolezo, umwini kapena zolemba m'zinthu zowonongeka zomwe ziribe mfundo izi, kapena kukhala ndi malamulo akuluakulu a mafayilo aakulu, monga MS-DOS.
bzip2 ndi bunzip2 zidzasinthika kuti zisayambe kuzilembapo . Ngati mukufuna kuti izi zichitike, tchulani -falipala.
Ngati palibe maina a fayilo atchulidwa, bzip2 imaphatikizira kuchokera kuzolowera zomwe zimaperekedwa kuyezo woyenera. Pachifukwa ichi, bzip2 idzalephera kulembera zolembedwera zomwe zimapangidwira kuti zikhale zogonjetsa, chifukwa izi sizikanamveka ndipo ndizosatheka.
bunzip2 (kapena bzip2 -d) imasokoneza maofesi onse. Mafayi omwe sanapangidwe ndi bzip2 adzawoneka ndi kusamalidwa, ndipo chenjezo linaperekedwa. bzip2 amayesa kuganiza fayilo la fayilo la fayilo yochotsedwera kuchokera ku fayilo yovomerezeka motere:
filename.bz2 imakhala filename
filename.bz amakhala filename
filename.tbz2 amakhala filename.tar
filename.tbz kukhala filename.tar
anyothername amakhala anyothername.out
Ngati fayilo siimathera kumapeto kovomerezeka , .bz2, .bz, .tbz2 kapena .tbz, bzip2 akudandaula kuti silingaganizire dzina la fayilo yoyamba, ndipo amagwiritsa ntchito dzina loyambirira ndi .out appended.
Mofanana ndi kupanikizika, kupereka mafayilo osayina amachititsa kusokoneza maganizo kuchoka muzolowera zomwe zimaperekedwa kuyezo woyenera.
bunzip2 idzakonza bwino decompress fayilo yomwe ikugwirizana ndi mafayilo awiri kapena ambiri ophatikizidwa. Chotsatira ndicho kuvomereza kwa maofesi osakanikizidwa omwe akugwirizana nawo. Kuyesera kudzipereka (-t) kwa maofesi ophatikizidwa ovomerezeka amathandizidwanso.
Mukhozanso kupondereza kapena kuchotsa maofesi pazomwe mumapereka popereka -c flag. Mafayilo angapangidwe ndi kuponderezedwa monga chonchi. Zotsatira zake zimadyetsedwa sequentially kuti ayambe. Kuphatikizidwa kwa maofesi angapo mwanjira imeneyi kumapangitsa mtsinje womwe uli ndi maimidwe ambiri opangidwa ndi mafayilo. Mtsinje wotere ukhoza kusokonezedwa molondola ndi bzip2 version 0.9.0 kapena kenako. Bzip2 zam'mbuyomu zidzatha pambuyo pochotsa deta yoyamba mumtsinje.
bzcat (kapena bzip2 -dc) imasokoneza mafayilo onse omwe akuwonekera pazomwe zimayambira .
bzip2 idzawerenga zifukwa zosiyana ndi zachilengedwe BZIP2 ndi BZIP, mwa dongosolo limenelo, ndipo zidzawatsogolera iwo asanayambe kutsutsana ndi mfundo iliyonse kuchokera ku lamulo la mzere. Izi zimapereka njira yabwino yopereka zifukwa zosasinthika.
Kulimbana nthawi zonse kumachitidwa, ngakhale fayilo yoponderezedwa ndi yaikulu kwambiri kuposa yoyambirira. Mafilimu osachepera pafupifupi zana zana amatha kukhala aakulu, popeza kupanikizika kumakhala kosalekeza m'dera la 50 bytes. Deta yosadziwika (kuphatikizapo zotsatira za mafayilo ambiri a compressors) amalembedwa pamtunda pafupifupi 8.05 podutsa, kupereka kufalikira kwa pafupi 0,5%.
Monga chowunikira cha chitetezo chanu, bzip2 imagwiritsa ntchito 32-bit CRCs kuti zitsimikizo kuti decompressed version ya fayilo ali ofanana ndi oyambirira. Alonda amenewa amatsutsana ndi ziphuphu za deta, komanso zotsutsana ndi ziphuphu zomwe sizidziwika . Mpata wa chiwonongeko cha deta chomwe sichidziwika ndi chochepa kwambiri, mwa mwayi umodzi pa mabiliyoni anayi pa fayilo iliyonse yomwe ikuchitidwa. Koma dziwani kuti chekeyi imabwera chifukwa cha kusokoneza maganizo, kotero zimangokuuzani kuti chinachake chalakwika. Sangathe kukuthandizani kubwezeretsa deta yoyamba yosasinthika. Mukhoza kugwiritsa ntchito bzip2recover kuti muyese kupeza deta kuchokera pazowonongeka.
Bweretsani mfundo: 0 kuti mutuluke bwino, 1 chifukwa cha mavuto a chilengedwe (mafayilo osapezedwa, mbendera zosavomerezeka, zolakwika za I / O, & c), 2 kuti asonyeze fayilo yowonongeka, 3 chifukwa cha kulakwitsa kwapakati (mwachitsanzo, bugulu) chomwe chinayambitsa bzip2 kuopsezedwa.

-f - ntchito
Limbikitsani kulembera za mafayilo owonetsera. Kawirikawiri, bzip2 sidzalembera mafayilo omwe akupezekapo. Imathandizanso kuti bzip2 iwononge maulendo olimba kwa mafayilo, omwe sangachite.
bzip2 kawirikawiri amachepetsa kufutukula maofesi omwe alibe mauthenga olondola amatsenga. Ngati kukakamizidwa (-f), komabe, kudutsa maofesi amenewa kupyolera mwa osadziwika. Umu ndi momwe GNU gzip imachitira.

Pewani kugwiritsa ntchito kukumbukira, kuponderezana, kuponderezana ndi kuyesedwa. Maofesi amatsitsimutsidwa ndipo amayesedwa pogwiritsa ntchito kusintha kosinthika komwe kumafuna maola awiri okha pa bolote. Izi zikutanthawuza kuti fayilo iliyonse ikhoza kubwezeretsedwa mu 2300k ya kukumbukira, ngakhale pafupi theka la liwiro labwino.
Panthawi ya kupanikizana, -sasankha kukula kwa 200k, zomwe zimapangitsa kuti chikumbumtima chisagwiritsidwe ntchito mofanana, poyerekeza ndi chiwerengero chanu. Mwachidule, ngati makina anu sakukumbukira (ma megabytes 8 kapena osachepera), gwiritsani ntchito-pa chirichonse. Onani MATHOMU NTCHITO pansipa.
