sed command in dry run

Question

How it is possible to make a dry run with sed?

I have this command:

find ./ -type f | xargs sed -i \'s/string1/string2/g\'

Answer 1

I would prefer to use the p-option:

find ./ -type f | xargs sed 's/string1/string2/gp'

Could be combined with the --quiet parameter for less verbose output:

find ./ -type f | xargs sed --quiet 's/string1/string2/gp'

From man sed:

p:

Print the current pattern space.

--quiet:

suppress automatic printing of pattern space
