npm install --global replace-in-files-cli$ replace-in-files --help
Usage
$ replace-in-files <files…>
Options
--regex Regex pattern to find (Can be set multiple times)
--string String to find (Can be set multiple times)
--replacement Replacement string (Required)
--ignore-case Search case-insensitively
--no-glob Disable globbing
Examples
$ replace-in-files --string='horse' --regex='unicorn|rainbow' --replacement='🦄' foo.md
$ replace-in-files --regex='v\d+\.\d+\.\d+' --replacement=v$npm_package_version foo.css

You can use the same replacement patterns as with `String#replace()`, like `$&`.
Real-world use-case: Bumping version number in a file when publishing to npm
The regex should be JavaScript flavor.
