How to save xxd or hexdump output to a simple file?-CodePudding

Is there a way to save the output to a file directly from the terminal? I give xxd command to a file on my terminal:

xxd image.jpg

and it gives me its contents in hex:

0003c450: 0124 9248 0492 4920 1249 2480 4924 9201  .$.H..I .I$.I$..
0003c460: 2492 4804 9249 2012 4924 8049 2492 0124  $.H..I .I$.I$..$
0003c470: 9248 0492 4920 1249 2480 4924 9201 2492  .H..I .I$.I$..$.
0003c480: 4804 9249 2012 4924 8049 2492 0124 9248  H..I .I$.I$..$.H
0003c490: 0492 4920 1249 2480 4924 9201 2492 4804  ..I .I$.I$..$.H.
0003c4a0: 9249 2012 4924 8049 2492 0124 9248 0492  .I .I$.I$..$.H..
0003c4b0: 4920 1249 2480 49db ba49 203f ffd9       I .I$.I..I ?..

What I want is to save these values in a file so that I can use them in another program. Is it possible from the terminal? If not how do I incorporate xxd or hexdump into a program?

This worked for me:

xxd image.jpg > image.txt

I now have a text file of the hex representation of the image.

My guess is that when you say you want to use the output "in another program", you mean you're going to compile it into something. This is what the -i option is for: generate an include file:

xxd -i image.jpg > image.h

Then #include image.h in your project and use the associated variables.
