ls - not a bug but a suggestion

[Paul Townsend]

Please forgive me if something like this exists already. I needed to find what 
files other than .gif files existed in a certain directory, and looked 
through the "ls" help to find a suitable option. There seemed to be nothing.

Something like:
        ls -l --not *.gif

where --not is the (currently non-existent) option to exclude the given 
filespec and show any other files (.bmp's, .tif's, etc. created by having the 
scanner in the wrong mode).

Regards
