Incazelo
Insiza ye-hexdump iyisihlungi esibonisa amafayela acacisiwe, noma ukufaka okujwayelekile, uma kungekho amafayela acacisiwe, kumfomethi ocacisiwe womsebenzisi.
Izinketho zilandelayo:
-b
Ukubonisa okukodwa kwe-octal Khombisa ukwehlukaniswa kokufakwayo ku-hexadecimal, kulandelwe i-split-split-separated, ikholomu ezintathu, i-octal, ngomugqa ngamunye.
-c
Ukubonisa komlingisi oyedwa- Khombisa ukukhipha okufakwayo ku-hexadecimal, okulandelwa yi-16 ehlukanisiwe isikhala, ikholomu ezintathu, igcwele indawo, izinhlamvu zedatha yokufaka ngomugqa ngamunye.
-C
Ukuboniswa kwe- hexical + ye-ASCII Ukubonisa ukuphawula kokufakwayo ku-hexadecimal, kulandelwe izihlukanisi eziyishumi nesithupha, ikholomu emibili, i-byte ye-hexadecimal, elandelwa yi-bytes ayishumi nambili ngo-% _p efakwe ezinhlamvu ze `` | ''.
-d
Ukubonisa kwedayimenti emibili ye-yedayikha Khombisa ukwehlukaniswa kokufakwayo ku-hexadecimal, kulandelwe yi-8 ehlukaniswe isikhala, ikholomu emihlanu, egcwaliswe ngokugcwele, amayunithi amabili-byte wedatha yokufaka, kumadayimenti angabhalisiwe, ngomugqa ngamunye.
-ifomathi_yifomethi
Cacisa ifomethi yefomethi okufanele isetshenziselwe ukubonisa idatha.
-f format_file
Cacisa ifayela eliqukethe izintambo zendlela yokwahlukanisa eyodwa entsha noma ngaphezulu. Imigqa engenalutho nemigqa yayo yokuqala engeyona ingenalutho ingumaki we-hashi ( # ayinaki.
-bude
Chaza ama-byte ubude bokufaka.
-o
Ukuboniswa kwe- octal amabili-mibono Khombisa ukwehlukaniswa kokufakwayo ku-hexadecimal, kulandelwe ukuhlukaniswa kwesibalo esiyisishiyagalombili, ikholomu eyisithupha, i-zero-egcwele, ubuningi be-intete yedatha yokufaka, ngo-octal, ngomugqa ngamunye.
-s offset
Yeqa ukukhipha ama-bytes kusukela ekuqaleni kokufaka. Ngokuzenzakalelayo, ukucasula kuhunyushwa njengenombolo yedesimali. Nge- offset ehamba phambili ye- 0x noma ye- 0X ihunyushwa njengenombolo ye-hexadecimal, kungenjalo, nge- offset ehamba phambili engu- 0 ihunyushwa njengenombolo ye-octal. Ukusebenzisa umlingisi b k noma m ukucasula kubangela ukuba kuhunyushwe njengenqwaba ye- 512 1024 noma i- 1048576 ngokulandelana.
-v
Okukhethwa kukho kwe - v kwenza i-hexdump ibonise yonke idatha yokufaka. Ngaphandle kokukhetha kwe- v , noma yiliphi inani lamaqembu womugqa ophumayo, ozofana neqembu eliphambili elilandelwayo lemigqa yokukhipha (ngaphandle kwalapho okufakwayo okufakwayo), kufakwe esikhundleni selayini elilodwa.
-x
Isibonisi se-hexadecimal ezimbili-byte Bonisa ukubeka okufakwayo ku-hexadecimal, kulandelwe yi-eight, isikhala esahlukile, ikholomu ezine, i-zero-egcwele, ubuningi be-intete yedatha yokufaka, ngo-hexadecimal, ngomugqa ngamunye.
Ngefayili ngayinye yokufakwayo, ukukopisha ngokulandelana kokufaka okokufaka kokukhipha okujwayelekile, ukuguqula idatha ngokusho kwezintambo ezifakwe izinketho ze- e ne- f , ngendlela ecacisiwe.
Amafomethi
Ifomethi yefomethi iqukethe noma yiliphi inani leyunithi yamayunithi, ehlukaniswe yi-whitespace. Iyunithi yesakhiwo iqukethe izinto ezintathu: ukubala kokulinganisa, ukubalwa kwe-byte, nesakhiwo.
Ukubalwa kwe-iteration kuyinani eliphelele lokuzikhethela, elingafani nelinye. Ifomethi ngayinye isetshenziswe izikhathi zokubala.
Ukubalwa kwe-byte kuyinamba enhle yokuzikhethela. Uma kukhonjisiwe ichaza inani lezintandokazi ukuthi lihunyushwe yi-iteration ngayinye yefomethi.
Uma inani lokulinganisa kanye / noma inani le- byte licacisiwe, ukushaywa okukodwa kumele kufakwe ngemuva kokubala kokulinganisa kanye / noma ngaphambi kokuba u-oct ubalekele ukuwahlukanisa.
Noma yikuphi ukukhanya kwe-whites ngaphambi noma emva kwe-slash kunganakwa.
Ifomethi iyadingeka futhi kumele ihambele ngokucaphuna kabili ("") amanothi. Ihunyushwa njengefomethi yefomethi yesitayela se-fprintf (bheka fprintf (3)), ngalezi zinto ezilandelayo:
- I-asterisk (*) ingase ingasetshenziselwa ububanzi bensimu noma ngokunemba.
- Ukubalwa kwe-byte noma ukucacisa kwensimu kuyadingeka kumlingisi ngamunye '`s' '(ngokungafani ne-fprintf (3) okuzenzakalelayo okushicilela uchungechunge lonke uma ukucacisa kungacacisiwe).
- Izinhlamvu zokuguqulwa `` h '', `` l '', `` n '', `` p '' ne `` q '' azixhaswa.
- Ukulandelana komlingisi oyedwa okuchazwe kumgangatho we-C kusekelwa:
I-NUL \ 0
\ a
\ b
\ f
\ n
\ r
\ t
\ v
U-Hexdump uphinde usekele izintambo ezilandelayo zokuguqula:
_a [ dox ]
Bonisa i-offset yokufakwayo, ukuqoqa kuwo wonke amafayela wokufaka, we-byte elandelayo ezoboniswa. Izinhlamvu ezixhunyiwe d o no- x zikhomba isisekelo sokubonisa njenge-decimal, i-octal noma i-hexadecimal ngokulandelanayo.
_A [ dox ]
Ngokufanayo ne- _a ukuguqulwa kwechungechunge ngaphandle kokuthi yenziwa kuphela kanye, lapho yonke idatha yokufaka isetshenzisiwe.
_c
Izinhlamvu zokukhishwa kusethi yezinhlamvu ezizenzakalelayo. Izinhlamvu ezingabhala phansi zingabonakaliswa ngohlamvu olulodwa, octal zero-padded, ngaphandle kwalabo abamelelwa ngokuphawula okujwayelekile (bheka ngenhla), okuboniswa njengezintambo ezimbili zomlingiswa.
_p
Izinhlamvu zokukhishwa kusethi yezinhlamvu ezizenzakalelayo. Izinhlamvu ezingabhala phansi zingaboniswa njenge-`` eyodwa . ''
_u
Izinhlamvu ze-US ASCII izinhlamvu, ngaphandle kokuthi ukulawula izinhlamvu kuboniswa ngokusebenzisa okulandelayo, amagama aphansi, amagama. Izinhlamvu ezinkulu kunezingu-0xff, i-hexadecimal, ziboniswa njengezintambo ze-hexadecimal.

Ukuzenzakalela nokusekelwa kwe-byte okubalwayo kubalingiswa bokuguqulwa kukhona kanje:
% _c,% _p,% _u,% c
I-byte eyodwa ibalwa kuphela.
% d,% i,% o % u,% X,% x
I-byte emine ehlulekile, okukodwa, okubili, nokunye okubalwe ngu-byte okusekelwayo.
% E,% e,% f % G,% g
I-byte yesishiyagalombili ehlukile, izibalo ezine ze-byte zisekelwe.
Isamba sedatha ehunyushwa ngetambo ngayinye yesakhiwo kungumumo wedatha edingekayo yunithi ngayinye yefomethi, okuyizinombolo zokubala kwe-atte ukubalwa kwe-byte, noma izikhathi zokubala kokulinganisa inani lezintatheli ezidingekayo ngefomethi uma inani le-byte lingekho okucacisiwe.
Okufakwayo kusetshenziswe ku `` blocks '', lapho ibhokisi ichazwa njengemali enkulu kakhulu yedatha ecaciswe yinoma yiluphi uhlobo lwefomethi. Amafomethi okufometha ahumusha ngaphansi kwedatha yokubamba kwedatha yokufakwayo, okuyi-unit yayo yokugcina kokubili ehumusha inombolo ethile ye-bytes futhi engenayo ukubalwa kokulinganisa, ukubalwa kokulinganisa kuze kube yilapho yonke ibhokisi lokufaka isetshenzisiwe noma kungekho idatha eyanele uhlale ebhodini ukwanelisa ifomethi yefomethi.
Uma, njengomphumela womklamo womsebenzisi noma i-hexdump eguqulela isibalo sokulinganisa njengoba kuchaziwe ngenhla, inani lokulinganisa likhulu kunelilodwa, izinhlamvu ze-whitespace ezilandelanayo zikhishwa ngesikhathi sokushayiswa kokugcina.
Kuyiphutha lokucacisa inani le-byte kanye nezinhlamvu eziningi zokuguqulwa noma izintambo ngaphandle kokuthi zonke izinhlamvu eziguquguqukayo noma ezilodwa noma i-strings yi- _a noma _A
Uma, ngenxa yenketho ye-in- n noma yokuphela kwefayela kufinyelelwe, idatha yokufakwayo iyanelisa ngokwanele ifomethi yefomethi, ibhokisi lokufaka liyi-zero-padded ngokwanele ukubonisa yonke idatha etholakalayo ukuphela kwedatha kuzobonisa inani elithile le-byte zet).
Ukukhishwa okuqhubekayo ngezintambo ezinjalo zefomathi kuthathwa indawo efana nendawo yezikhala. Inombolo elinganayo yezikhala ichazwa njengenombolo yezikhala ezikhishwa ngumlingiswa wokuguqulwa ngu- s ngebanga elifanayo lezinsimu nokucaca njengobunikazi bokuqala bokuguqula noma izintambo zokuguqulwa kodwa nganoma yikuphi `` + '' `` '' `` `'' ' ukuguqulwa kwezinhlamvu zefulegi kukhishiwe, futhi kubhekisela ucingo lwe-NULL.
Uma kungekho izintambo zokufometha ezicacisiwe, ukubonisa okuzenzakalelayo kufana nokucacisa i- x inketho.
iphuma 0 ngokuphumelela futhi> 0 uma kwenzeka iphutha.
EXAMPLES
Khombisa okokufaka kufomethi yokwenza:
"% 06.6_ao" 12/1 "% 3_u" "\ t \ t" "% _p" "\ n"Qalisa inketho ye--x:
"% 07.7_Ax \ n" "% 07.7_ax" 8/2 "% 04x" "\ n"Amazinga
I-utility ilindeleke ibe yi-St -p1003.2 ehambisanayo.
