I want to migrate a domain from a server to another. I want to find and replace all the strings with the old name with the new one using ssh. What is the right command in putty?

For example find John inside the files of a folder and rename it with Bill

for replacing single file you can use

sed -i -e 's/John/Bill/g' /tmp/file.txt

and for searching files you can use 

find . -name "*.txt" -print

when you combine them with -exec, you will get the result which you are looking for.

find . -name "*.txt" -exec sed -i -e 's/John/Bill/g' {} +
