Use Git Grep to Replace Strings in Files in Your Git Repository
git grep -l 'original_text' | xargs sed -i 's/original_text/new_text/g'
git grep -l 'original_text' | xargs sed -i '' -e 's/original_text/new_text/g'
I needed to change a string in a bunch of files and I used the command above using git grep to do it. Worked like a charm.
-l argument to git grep only returns the file names and not the location in the file like it usually does.
-e argument is needed with the
sed portion on OSX as stated by asmeurer in the comments
