How to do a recursive find/replace of a string with awk or sed?

Question

How do I find and replace every occurrence of:

subdomainA.example.com

with

subdomainB.example.com

in eve

Answer 1

just to avoid to change also

• NearlysubdomainA.example.com
• subdomainA.example.comp.other

but still

• subdomainA.example.com.IsIt.good

(maybe not good in the idea behind domain root)

find /home/www/ -type f -exec sed -i 's/\bsubdomainA\.example\.com\b/\1subdomainB.example.com\2/g' {} \;
