   I don't think it's a corner case, quotes have a special effect in bash, we 
shouldn't change the user command.
   
   ```
   spec:
     containers:
     - command:
       - echo
       - '''$SHELL'''
   ```
   
   * It's weird in `'''$SHELL'''` since the input is `'$SHELL'`, it seems to be 
related to k8s
   * Is there a better solution for this? My suggestion is to not introduce new 
problems until we find a better way to solve the problem of quotes
