check whether you installed the package xxd or not  ( by which xxd  or whereis xxd )

 

you can use the command  also like this to dump the hex code.

 

xxd abc.o > hex.txt

the command is right but the hex.txt generated is not understandable.

     Here hex.txt is a file, created by me, into which i am redirecting the command output ( stdout )

Well lests say the file to be abcd.o

if you want a good view in 'less' its better you use hexdump. its a frontend of xxd. the command is :

$hexdump -C abcd.o |less

you may redirect it to another file to use it later than running hexdump each time.

$hexdump -C abcd.o> abcd.txt

else you can use well known hex editor like 'Okteta' to get things done.
