Change a String in Every File in a Tree

Suppose I'd like to replace every 'string' with 'newstring' in the directory ~/directory:

Good:

find . -type f -print0 | xargs -0 sed -i 's/string/newstring/g'


Better:

grep -lrZ string | xargs -0 sed -i 's/string/newstring/g'


Best:

git grep -lz 'string' | xargs -0 sed -i 's/string/newstring/g'


Bester:

git grep -lz 'string' ~/directory | xargs -0 sed -i 's/string/newstring/g'
