The main thing to remember is the mantra `brace expansion is not globbing'. When you use braces, all elements are generated regardless. Here, you get: xview 02.*jpg 03.*jpg 04.*jpg ... 19.*jpg before globbing kicks in. Are you simply trying to match a set of numbered files of which you're pretty sure some are there, but not all? Then the obvious thing to try is: xview <2-19>.*jpg There's no special handling for a leading zero here, but it will match one if present. If you want to be strict about the numeric format, then you need to keep the braces. Luckily, in this case you still have the `*', so the set of arguments generated are still globbing patterns. Thus you can get away with: xview {02..19}.*jpg(N) which turns on the NULL_GLOB option for all the patterns. Then any that don't match anything will simply be removed. What you *might* want in this case is for an error to be caused if and only if there were no matches to any pattern. With the form in angle brackets, that's what you get with your current option settings (since there is only one pattern). With the form in braces, you would need to `setopt csh_null_glob' to get this: setopt cshnullglob xview {02..19}.*jpg -- Peter Stephenson <pws@csr.com> Software Engineer CSR Ltd., Science Park, Milton Road, Cambridge, CB4 0WH, UK Tel: +44 (0)1223 692070 ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

And n should be determined from the first arg that commences in a non [-()0-9] character. -- Eric Smith ^ permalink raw reply [flat|nested] 7+ messages in thread

I'd be inclined to check all characters: (^[-()0-9]#) You could use a loop to do the same. ^ permalink raw reply [flat|nested] 7+ messages in thread
