    I am writing a shell script (#!/bin/sh) that will change some file names
    around but am having trouble formatting a string. If I have a string like
    this:
    20050202
    How can I change it to:
    2005-02-02

    I have about a thousand files so it isn't really feasable for me to be
    changing the names manually. All of the files are similar to this and I
    have everything in the script to make the change but this one problem.
    I have looked into "printf" and "awk/split", but I don't think either one
    of these would work for me. Maybe one would, but I just couldn't figure it
    out. Any help would be appreciated.

    Thanks
    Steve
