Answer 1

For me the easiest solution to remember is https://stackoverflow.com/a/2113224/565525, i.e.:

sed -i '' -e 's/subdomainA/subdomainB/g' $(find /home/www/ -type f)

NOTE: -i '' solves OSX problem sed: 1: "...": invalid command code .

NOTE: If there are too many files to process you'll get Argument list too long. The workaround - use find -exec or xargs solution described above.
