RE: Looping through files

[Leslie Rhorer]

My guess would be the shell included with Grub does not provide the `ls`
command.  It also may not recognize process redirection.

Thanks for the suggestion

I just tried this but it didn't work:
 error: syntax error.
 error: incorrent command.
 error: syntax error

It seems strange that it is not possible to script looping through files on
the boot disk.

As background, what I am trying to achieve is to include menu items
dynamically based on whether certain files exist on the disk. I could do
that with "if [-e ..." as I have done and tested this to work OK. However I
don't want to have to hardcode which files I wish to check for
