title: How to create a hex dump of file containing only the hex characters without spaces in bash?
body: <p>How do I create an <strong>unmodified</strong> hex dump of a binary file in Linux using bash? The <code>od</code> and <code>hexdump</code> commands both insert spaces in the dump and this is not ideal.</p>
  
  <p>Is there a way to simply write a long string with all the hex characters, minus spaces or newlines in the output?</p>
