title: How to separate one .jpeg file into several original ones?
body: <p>So, I was messing around with bash, and accidentaly merged several .jpg files that had .txt extension into one .jpg. The stupidity I wrote was </p>
  
  <pre><code>mv ./*.txt .jpg
  </code></pre>
  
  <p>Any ideas on how I could undo it? the file created has a size that's compatible with the size of the other files all merged so I guess it's all there, but can't figure how to separate the binary...</p>
  
  <p>(yes, why on earth did I do it? who the hell knows)</p>
  
  <p>Thanks for your help.</p>
