Re: [U-Boot] [PATCH] common: cli_hush: Do a simple recursive variables parsing

Dear Simon,

In message CAPnjgZ1j=yNOSbmDU0Pkq2y1wq-y=v7O2y7zPTNEfc==St3rgQ@mail.gmail.com you wrote:

I think your change would causes non-standard shell behaviour.

If you want to evaluate variables, you have to do so as part of a "run" command...

I find the recursive behaviour much more useful. In particular we have to jump through all sorts of hoops to build up a command line. It would be much easier if we could make things recursive. The single quote example above explicitly stops all substitution - do we need a way to do that also?

Useful it may be - in samoe cases at least, but I think it is a very bad idea to deviate from standard shell behaviour.

Best regards,

Wolfgang Denk
