Hexdump -C but decimal instead of hex

Question

centos 6.5 - running hexdump

$ hexdump -C filecsv
00000000  44 4f 53 2c 20 50 61 74  69 65 6e 74 2c 20 41 63  |DOS, Patient, Ac|
00000010  63 74 20 23 2c 20 4d 52  20 23 2c 20 54 69 6d 65  |ct #, MR #, Time|

Love this format but want hex to be converted to decimal I have spent time looking but cannot find this?

Answer 1

hexdump supports specifying a format string via the -e command-line option, and it seems to be pretty flexible.

Example:

$ hexdump -C b.c
00000000  23 69 6e 63 6c 75 64 65  20 3c 73 74 64 69 6f 2e  |#include <stdio.|

00000020  20 70 72 69 6e 74 66 28  22 68 65 6c 6c 6f 20 77  | printf("hello w|
00000030  6f 72 6c 64 5c 6e 22 29  3b 0a 20 20 72 65 74 75  |orld\n");.  retu|
00000040  72 6e 20 30 3b 0a 7d 0a                           |rn 0;.}.|

$ hexdump -e'"%07.8_ax  " 8/1 "%02x " "  " 8/1 "%02x " "  |"' -e'16/1  "%_p"  "|\n"' b.c
00000000  23 69 6e 63 6c 75 64 65  20 3c 73 74 64 69 6f 2e  |#include <stdio.|

$ hexdump -e'"%07.8_ad  " 8/1 "%03d " "  " 8/1 "%03d " "  |"' -e'16/1  "%_p"  "|\n"' b.c

Not sure about how to reproduce that last line produced by -C.
