Kufotokozera
Hexdump amagwiritsidwa ntchito ndi fyuluta yomwe imasonyeza maofesi ofotokozedwa, kapena kuyika koyenera, ngati palibe mafayilo omwe atchulidwa, mu mawonekedwe osankhidwa.
Zosankha ndi izi:
-b
Chiwonetsero cha octal chimodzi Chiwonetsero chotsalira chokhalapo mu hexadecimal, chitatsatidwa ndi khumi ndi zisanu ndi chimodzi-ogawanika, ndondomeko zitatu, zero-zodzazidwa, zolemba za ma input, octal, pa mzere.
-c
Chiwonetsero chimodzi chowonetsera Chiwonetseratu chikhomo choyambira mu hexadecimal, tsambulidwa ndi magawo khumi ndi asanu ndi limodzi, ogawanika, malo odzaza malo, zilembo za deta yoyenera pa mzere.
-C
Zithunzi zamakono zowonongeka za ASCII Zisonyezerani zoyipa zolembapo mu hexadecimal, zotsatiridwa ndi khumi ndi zisanu ndi chimodzi zogawidwa, malo awiri, hexadecimal byte, zotsatiridwa ndi zofanana ndi khumi ndi zisanu ndi chimodzi mwa% _p zojambulidwa mu zilembo za `` | ''.
-d
Dongosolo lachiwiri-tote likuwonetsa Kuwonetsa chotsalira cholowera mu hexadecimal, lotsatidwa ndi magawo asanu ndi atatu osiyana-siyana, ndime zisanu, zero-zodzazidwa, magawo awiri a byte a data input, mu decimal unsigned, pa mzere.
-mapangidwe_songa
Tchulani chingwe chojambulidwa kuti chigwiritsidwe ntchito powonetsera deta.
-fomangidwe_mafayilo
Tchulani fayilo yomwe ili ndi zingwe zosiyana kapena zowonjezera zatsopano zosiyana. Mzere wopanda mizere ndi mizere yomwe yoyamba yosakhala yopanda kanthu ndi chizindikiro cha hayi ( # zili zosasamala.
-kutalika
Tanthauzani maulendo autali okhawo owonjezera.
-o
Zojambula ziwiri za octal Kuwonetsa zolemba zolowera mu hexadecimal, zotsatidwa ndi magawo asanu ndi atatu osiyana, malo asanu ndi limodzi, zodzazidwa ndi zero, mavoti awiri a ma input, octal, pa mzere.
-kutsutsana
Lembani zoyimphana zokhazikika kuyambira pachiyambi cha zolembera. Mwachikhazikitso, kulakwitsa kumasuliridwa ngati nambala ya decimal. Ndi chonchi chotsogolera 0x kapena 0X chikutanthauziridwa ngati nambala ya hexadecimal, mwinamwake, ndi kutsogolera 0 kutsogolo kumatanthauziridwa ngati nambala ya octal. Kugwiritsa ntchito chikhalidwe b k kapena m kukhumudwitsa kumachititsa kuti zimasuliridwa ngati ochuluka a 512 1024 kapena 1048576 motsatira.
-v
Chotsatira cha - v chimayambitsa hexdump kuti isonyeze deta zonse zolowera. Popanda chochita, vutolo lirilonse la zolembera mzere, zomwe zingakhale zofanana ndi magulu omwe amatsogoleredwapo (kupatulapo zoperekera), amaloledwa ndi mzere wopangidwa ndi asterisk imodzi.
-x
Mawonedwe awiri a hexadecimal Onetsetsani zoyipa zolowera muzithunzi zam'manja, zotsatiridwa ndi zisanu ndi zitatu, malo osagawanika, ndime zinayi, zodzazidwa ndi zero, mavoti awiri a zolembera, mu mzere wache, pamzere.
Pa fayilo iliyonse yowunikira, sequentially imapereka zolembera ku zowonongeka, kusintha ma deta molingana ndi masankhulidwe owonetsedwa ndi zosankha za- e -- f , malinga ndi momwe adanenera.
Zimapanga
Mndandanda wa maonekedwe uli ndi mayina angapo a mawonekedwe, olekanitsidwa ndi whitespace. Chigawo chokhala ndi maonekedwe chimakhala ndi zinthu zitatu: kuwerengera kwayeso, kuwerengetsera kwao, ndi mtundu.
Kuwerengera kwa iteration ndichinthu chofunikira chokhazikika, chomwe chimasokonekera kwa chimodzi. Mtundu uliwonse umagwiritsidwa ntchito nthawi yowerengera nthawi.
Chiwerengero cha ochepa chiwerengero ndi chofunika chokhazikika. Ngati zidafotokozedwa, zikutanthauzira chiwerengero cha maofesi kuti chitanthauzidwe ndi machitidwe ake onse.
Ngati kuwerengera kuwerengera ndi / kapena kuwerengetsera kwachuluka kwafotokozedwa, kuperewera kumodzi kumayenera kuikidwa pambuyo pa kuwerengera kwa chiwerengero ndi / kapena asanayambe kuwerengera.
Choyimitsa whitespace musanayambe kapena pambuyo pake.
Maonekedwe amafunika ndipo ayenera kuzunguliridwa ndi malemba awiri (""). Amatanthauziridwa ngati chingwe cha mtundu wa fprintf (onani fprintf (3)), ndi zina zotsatirazi:
- Asterisk (*) sangagwiritsidwe ntchito ngati munda wamtunda kapena molondola.
- Chiwonetsero chowerengera kapena chamunda chofunikira chikufunika pa mtundu uliwonse `` s '' kutembenuza (mosiyana ndi fprintf (3) yosasintha yomwe imajambula chingwe chonse ngati chanenedwa chiri chosadziwika).
- Kutembenuka malemba `` h '', `` '', `` n '', `` p '' ndi `` q '' sali othandizidwa.

Hexdump imathandizanso zowonjezera zotsatirazi:
_a [ dox ]
Onetsani zoyipa zoyenera, zowerengera pa mafayilo olowera, pa otsatira otsatira kuti awoneke. Manambala omwe ali pamtunduwu d o ndi x amatchula maziko owonetsera monga decimal, octal kapena hexadecimal motsatira.
_A [ dox ]
Mofananamo ndi_a chingwe chowongolera kupatula kuti icho chimangochitidwa kamodzi, pamene deta zonse zowunikira zatha.
_c
Otsatsa malingaliro ali mu khalidwe losasinthika. Zithunzi zosasindikiza zikuwonetsedwa mu chikhalidwe chachitatu, zero-padded octal, kupatulapo omwe amawoneka ndi zolemba zapamwamba (onani pamwambapa), zomwe zikuwonetsedwa ngati zingwe ziwiri.
_p
Otsatsa malingaliro ali mu khalidwe losasinthika. Zithunzi zosasindikiza zikuwonetsedwa ngati '` . ''
_u
Zotsatira za ma ASCII a US, kupatula kuti olamulira malemba akuwonetsedwa pogwiritsa ntchito zotsatirazi, zochepa, mayina. Anthu aakulu kuposa 0xff, hexadecimal, amawonetsedwa ngati zingwe za hexadecimal.

Kuchuluka kwa deta kumasuliridwa ndi ndondomeko iliyonse ya maonekedwe ndi chiwerengero cha deta yomwe ili ndi gawo lililonse, yomwe ndi nthawi yowerengera nthawi yowerengeka, kapena nthawi yowerengera nthawi yomwe chiwerengerocho chimafunikanso ngati chiwerengerocho sichipezeka atchulidwa.
Zowonjezera zimagwiritsidwa ntchito mu `` Blocks '', kumene malowa amatchulidwa ngati kuchuluka kwa deta yomwe imatchulidwa ndi chingwe chilichonse. Zingwe zojambulidwa zosindikizira zochepa zowonjezera zowonjezera deta, zomwe zomaliza zija zimasulira ziwerengero zinazake ndipo sizikhala ndi chiwerengero chowerengera, chiwerengero chowerengera chikuwonjezeredwa mpaka zonse zowonjezera zowonongedwa kapena palibe deta yokwanira khalani mu chipika kuti mukwaniritse chingwe chojambulidwa.
Ngati, mwina chifukwa cha kutchulidwa kwa wogwiritsira ntchito kapena hexdump kusintha kuwerengera kwayeso monga tafotokozera pamwambapa, chiwerengero cha kuchepetsa chiwerengero choposa chiwerengero chimodzi chokha, chotsatira cha whitespace chomwe chimachokera pamapeto otsiriza.
