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

For replace all occurrences in a git repository you can use:

git ls-files -z | xargs -0 sed -i 's/subdomainA\.example\.com/subdomainB.example.com/g'

See List files in local git repo? for other options to list all files in a repository. The -z options tells git to separate the file names with a zero byte, which assures that xargs (with the option -0) can separate filenames, even if they contain spaces or whatnot.
