    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

    Try this:

    ls [0-Z][0-Z][0-Z][0-Z][0-Z][0-Z]-*.jpg|while read i
    do
    echo $i|sed s/-/*/|sed s'/-/ /'g
    done

    [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
