I'm unable to reproduce the issue with the code sample you provided. I believe we don't never flag module-level variables as unused, but even after moving the code inside a function I don't see escaped_command flagged as unused:

If I comment out the print call, escaped_command is flagged as unused:

Can you provide a more complete code sample that reproduces the issue?
