linux command to find files and replace with another file

Question

I'm looking for a linux command to search a folder directory and it's subfolders for a file by name and replace all of them with a copy of another file. Any idea?

Answer 1

Assuming you have the replacement file in your home directory (~), you can use find to do the replacing. This will find all boom.txt files and replace them with the replace.txt file (keeping the boom.txt name).

find . -name "boom.txt" -exec cp ~/replace.txt {} \;
