Rename is cool :) I just recently used it a few times, and was very happy
with what I could do with it (much more than mv).
I do have a question about grep and stuff... I would like to replace text
with different text (like change alt= tags to title= or duplicate alt tags to
title tags... so, If i have something like
<a href="www.rocksolidnetworks.com"><img src="rock.jpg" alt="picture of
rock"></a>
and I want
<a href="www.rocksolidnetworks.com"><img src="rock.jpg" alt="picture of rock"
title="picture of a rock"></a>
What is the easiest way (yes, I could read awk, and sed and grep...) but I
basicly just want a rename for inside files (not just filenames).
