regex - Rename a string from app.js to app.min.js in bash

Question

What's the quickest way to take a string like "app.js" and rename it to "app.min.js" in bash?

I was hoping for an awk regex or something where I can do:

s/(.*?)\.js/$1.min.js/

Answer 1

这是一种方式：

string=app.js
string=${string/./.min.}
