title: using a Bash variable in place of a file as input for an executable
body: <p>I have an executable that is used in a way such as the following:</p>
  
  <pre><code>executable -v -i inputFile.txt -o outputFile.eps
  </code></pre>
  
  <p>In order to be more efficient, I want to use a Bash variable in place of the input file. So, I want to do something like the following:</p>
  
  <pre><code>executable -v -i ["${inputData}"] -o outputFile.eps
  </code></pre>
  
  <p>Here, the square brackets represent some clever code.</p>
  
  <p>Do you know of some trick that would allow me to pipe information into the described executable in this way?</p>
  
  <p>Many thanks for your assistance</p>
