Search and Replace

Recursively search a directory for files containing "this" and replace it with "that":

find . -type f -print0 | xargs -0 sed -i 's/this/that/g'

or

sed -i 's/this/that/g' `grep -lR --include=\*.txt 'this' .`

If you are on a Mac:

find . -name '*.txt' | xargs perl -pi -e 's/this/that/g'
