how to write script to change email address

we have 4000 html pages that need an email address changed.

eg) to

we only want the file modified date to be changed when there has been a change to the file.

Should I be using grep?

I fairly new to UNIX and was told to using something like this

find /qlinx/common/quicklinks/docs/700_799/ -name "*.htm" -type f | \
xargs perl -pi -e 's/\/company-information\/legal-and-regulatory/\/legal-and-regulatory/g'

however this changes the file modified date weather or not information was change

Please define what constitutes a "change to the file" and precisely how you detect this change? In general "change" needs a timebase.

the script will have to check each html page to see if it has the email address that needs to be replaced with the new email address. However, I do not want the file modified date to change unless the email address has been changed to the new address.
