Hi All

How to dump the corresponding Hex value for each character using od or
other unix command ? Print original character and the hex value.

Data as below

Try use `hexdump'
admin(a)phoenix:/home/admin>printf "A" | hexdump -x -C
0000000 0041
00000000 41 |A|
00000001

I am an eternal noob, so this may be over complicated or over simplified.

# make a loop putting one character in CHAR for each iteration
for CHAR in A B C 1 2 3;
# echo the character followed by a space, without a newline
do echo -n "$CHAR "
# echo the character again, and pipe it to xxd
# the -p option to xxd give plain output
echo -n $CHAR | xxd -p;
# end loop
done

$ cat file
A
B
C
1
2
3

$ gawk '{print $0,strtonum("0x"$0)}' file
A 10
B 11
C 12
1 1
2 2
3 3

$ gawk --non-decimal-data '{printf "%s %d\n",$0,"0x"$0}' file
A 10
B 11
C 12
1 1
2 2
3 3

$ while read c; do printf "%s %d\n" "$c" "0x$c"; done < file
A 10
B 11
C 12
1 1
2 2
3 3

Note that both --non-decimal-data and strtonum() are GNU awk
extensions and that final example was in bash.

awk '
BEGIN{for (i=0;i<256;i++) x[sprintf("%c",i)]=sprintf("%x",i)}
{print $0, x[$0]}'

Or:

perl '-lpe$_=join$",unpack"aXH2",$_'
