I- cmp Ubungakanani obuqhathanisa iifayile ezimbini zaliphi na uhlobo kwaye lubhala iziphumo kumgangatho oqhelekileyo. Ngokungagqibekanga, i- cmp ithe cwaka xa iifayile zifana; ukuba ahluke, i-byte kunye nenombolo yomgca apho ukuhlukana kokuqala kwenzeka khona kubikwa.
Imiqulu kunye nemigca ibalwa ukusuka ekuqaleni.
Isiqendu
cmp [- l | -s ] ifayile1 fayile2 [ skip1 [ skip2 ]]
Tshintsha
Ukutshintsha okulandelayo kwandisa ukusebenza komyalelo:
-l
Phrinta inombolo ye-byte (i-decimal) kunye nemilinganiselo ye-byte (i-octal) nganye.
-s
Phrinta nto yeefayili ezahlukeneyo; ukubuya kwemoya yokuphuma kuphela.
& # 34; Yehlisa & # 34; Iingxoxo
Iingxoxo ezikhethiweyo ze- skip1 kwaye ziweqa i-oto bytes ukususela ekuqaleni kwefayile1 kunye nefayile2 ngokulandelanayo, apho kuqhathaniswa khona. I-offset iyimimiselo engagqibekanga, kodwa ingabonakaliswa njengexabiso elingu-hexadecimal okanye i-octal ngokulilandelelanayo nge- 0x okanye 0 ekhokelayo.
Ukubuyisela amaxabiso
Umbutho we- cmp uphuma ngenye yexabiso elilandelayo:
0- Iifayile ziyafana.
1- Iifayile ziyahlukileyo; eli xabiso liquka imeko apho ifayile enye ifana nengxenye yokuqala yenye. Kwimeko yokugqibela, ukuba ukhetho olungenakucacisiwe , i- cmp ibhala kwimveliso eqhelekileyo eyenziwa ngu-EOF kwifayile emfutshane (phambi kokuba kukho intlukwano).
> 1- Iphutha lenzekile.
Amanqaku okuSebenzisa
Umyalelo ohlukileyo (1) wenza umsebenzi ofanayo.
Umbutho we- cmp kulindeleke ukuba ube ngu-St -p1003.2 ehambelanayo.
Ngenxa yokuba izabelo kunye namazinga okukhululwa kernel ahluke, sebenzisa umyalelo womntu ( % umntu ) ukuze ubone indlela nayiphi na umyalelo othize osetyenziswa kukhompyutha yakho ethile.
