lerna: Run a specific script for every package that contains it in its `package.json`.

lerna

$ lerna run ${script}

The command "lerna run ${script}" is typically used in projects that utilize Lerna, a tool for managing JavaScript projects with multiple packages. Lerna allows you to manage the packages within a project by providing various commands to execute tasks across all packages or specific ones.

In the command "lerna run ${script}", ${script} is a placeholder that represents the name of the script or task you want to execute. You should replace ${script} with the actual name of the script you wish to run.

When you execute this command, Lerna will run the specified script across all packages in your project or only in the packages that are specified in the command. This is particularly useful when you want to perform a particular task, like building or testing, on multiple packages at once.

For example, let's say you have a project with three packages: package1, package2, and package3. If you run "lerna run build", Lerna will find the "build" script in each package's package.json file (if available) and execute it. It will sequentially run the build script in package1, package2, and package3.

The "lerna run" command offers additional options and flags that allow you to control how the scripts are executed, which packages are targeted, etc. You can refer to Lerna's documentation for detailed information on these options and how to use them.
