[geeks] search and replace

[Kevin]

I've got an folder full of html docs that reference a
file in one location and i want to move that file to
another location.  What i need is a way of replacing
the string "pic.gif" with the string "images/pic.gif"
in all of these documents.

I'm guessing there is someway to accomplish this with a
bash or csh script but i lack a mastery of either.  Any
help would be much appreciated.

Note: i'm sure i could load up all the files into a
word processor and search and replace but i feel
certain that there's a more elegant way :)

Thanks,
