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

This one is compatible with git repositories, and a bit simpler:

Linux:

git grep -l 'original_text' | xargs sed -i 's/original_text/new_text/g'

Mac:

git grep -l 'original_text' | xargs sed -i '' -e 's/original_text/new_text/g'

Answer 2

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.

Answer 3

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.

Answer 4

cd /home/www && find . -type f -print0 |
  xargs -0 perl -i.bak -pe 's/subdomainA\.example\.com/subdomainB.example.com/g'

Answer 5

For anyone using silver searcher (ag)

ag SearchString -l0 | xargs -0 sed -i 's/SearchString/Replacement/g'

Since ag ignores git/hg/svn file/folders by default, this is safe to run inside a repository.

Answer 6

The simplest way for me is

grep -rl oldtext . | xargs sed -i 's/oldtext/newtext/g'
