title: Using hexdump to output only ASCII
body: <p>I'm trying to output ASCII values corresponding to some binary data. I have successfully applied the <code>hexdump</code> utility to output hexdump and ASCII side-by-side as below: </p>
  
  <pre><code>00000120  20 20 20 20 3d 20 30 78  30 30 30 30 30 30 33 30  |    = 0x00000030|
  00000130  0a 01 00 00 00 23 00 00  00 75 75 69 64 30 20 20  |.....#...uuid0  |
  00000140  20 20 20 20 20 20 20 20  20 20 20 20 20 20 20 3d  |               =|
  00000150  20 30 78 39 30 38 32 61  63 35 61 0a 01 00 00 00  | 0x9082ac5a.....|
  00000160  23 00 00 00 75 75 69 64  31 20 20 20 20 20 20 20  |#...uuid1       |
  00000170  20 20 20 20 20 20 20 20  20 20 3d 20 30 78 37 34  |          = 0x74|
  00000180  61 37 34 37 36 66 0a 01  00 00 00 23 00 00 00 75  |a7476f.....#...u|
  00000190  75 69 64 32 20 20 20 20  20 20 20 20 20 20 20 20  |uid2            |
  000001a0  20 20 20 20 20 3d 20 30  78 61 32 35 35 35 63 30  |     = 0xa2555c0|

  <p>However, I would like to see only the ASCII as output values. I'm not interested in the hex values. For example, the output should be the following (approx. corresponding to the above): </p>
  
  <pre><code>= 0x00000030.....#...
  uuid0=0x9082ac5a.....
  uuid1=0x74a7476f
  </code></pre>
  
  <p>(I haven't been able to use the switches of <code>hd</code> for this.)</p>
