Hi,

I need help constructing a script that will do the following -

1. find all filenames that begin with 6 characters (alphanumeric) followed by a '-' AND that end in .jpg.

2. then I need to rename each of the files so that the first '-' is replaced by a '*' and all remaining '-' are replaced by a space ' '.

I'm running OSX using the t shell.

Cheers.

Michael

[0-Z][0-Z][0-Z][0-Z][0-Z][0-Z]-*.jpg

Should that not be a "-.*.jpg"

That would only match a file ending in any number of '-'s
