ack <search term> -l --print0 | xargs -0 sed -i '' 's/<search term>/<replacement term>/g'

• ack takes a search term, and with the -l flag, it outputs only filenames
• --print0 separates filenames with a null byte instead of a newline. This is nice for filenames that contain spaces (non programmers!)- We take the resulting list and pipe it to xargs which will iterate over each listing and applies the following command. Note the -0 flag so that it knows to look for the null byte character
