[Gimp-user] batch image convert to rgb

[HarryH <forums gimpusers com>]

Hi

Just trying a batch in a folder of png files, want to convert from indexed mode
to rgb. Followed GIMP help instructions for batch convert via terminal (I'm
using Xubuntu 14.04 if that makes any difference).

I tried this and got an error:

gimp -i -b '(gimp-image-convert-rgb "*.png")' -b '(gimp-quit 0)'
batch command experienced an execution error:
Error: ( : 1) Invalid type for argument 1 to gimp-image-convert-rgb 

Can anyone explain to me what I did wrong?

Cheers
