Find and replace using xargs sed - can I save the results to a file?

Question

My code to replace all instances of 'foo' with 'bar' :

find . -type f |
xargs grep 'foo' -l |
xargs sed -i 's|foo|bar|g'

I'd like to save a list of the modified files to a text document. Is it possible?

EDIT :

This is the final code that worked for me :

find . -type f -print0 |
xargs -0 grep 'foo' -l |
tee result.txt |
xargs -0 sed -i 's|foo|bar|g'

Not sure whether this is the quickest way, but for a few thousand files the difference in speed between this and other suggested methods is probably very small.

Looks like a useless use of xargs, as often in combination with find.

find . -type f -exec grep 'foo' -l {} ";" -exec sed -i 's|foo|bar|g' {} ";" -ls > file.lst

Use it with care, since I didn't test it. I'm not sure, whether you like to change the list of filenames, or the file content. Since you search with grep and sed, I think only working with sed should be sufficient:

find . -type f -exec sed -i 's|foo|bar|g' {} ";" -ls > file.lst
