title: Command 'blender' not found, despite executing from the installed directory
body: <p>I am trying to execute a python file using the python from blender. I have downloaded and placed the blender inside my user's home directory. But everytime I try to execute blender command I get the following error:</p>
  
  <pre><code>Command blender not found, but can be installed with:
  sudo snap install blender  # version 2.79b, or
  sudo apt  install blender
  See 'snap info blender' for additional versions.`
  </code></pre>
  
  <p>My current directory is:</p>
  
  <p><code>$ pwd
  /home/rishik/Applications/blender-2.79b-linux-glibc219-x86_64</code></p>
  
  <p>I executed the following:</p>
  
  <p><code>blender --background python somepythonfile.py</code></p>
  
  <p>I do not understand how to invoke python from blender now.</p>
