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

Note: Do not run this command on a folder including a git repo - changes to .git could corrupt your git index.

find /home/www/ -type f -exec \
    sed -i 's/subdomainA\.example\.com/subdomainB.example.com/g' {} +

Compared to other answers here, this is simpler than most and uses sed instead of perl, which is what the original question asked for.
