Below is an example how to run a script from another with npm in package.json.
What's the equivalent with yarn?
{
"name": "npm-scripts-example",
"version": "1.0.0",
"description": "npm scripts example",
"scripts": {
"clean": "rimraf ./dist && mkdir dist",
"prebuild": "npm run clean",
}
}

Approach 1(npm-run all package): We can use the” npm-run all” package to run different scripts at the same time. First, we have to install the package itself by using the command. After installation of the package we have to navigate to the package.
postinstall is called after a package's dependency tree changes are written to the disk -- e.g. after a dependency or transitive dependency is added, removed, or changed. It is guaranteed to be called in topological order (in other words, your dependencies' postinstalls will always run before yours).
Running yarn <command> [<args>] will run the command, if it is matching a locally installed CLI. So you don't need to setup user-defined scripts for simple use cases.
Yarn can consume the same package. json format as npm, and can install any package from the npm registry. This will lay out your node_modules folder using Yarn's resolution algorithm that is compatible with the node.
You could do
{
"name": "npm-scripts-example",
"version": "1.0.0",
"description": "npm scripts example",
"scripts": {
"clean": "rimraf ./dist && mkdir dist",
"prebuild": "yarn run clean",
}
}
And then the command yarn run prebuildshould work.
Also you could just do yarn run clean.

Improving on @l-faros answer, Yarn also supports a shorter syntax
{
"scripts": {
"clean": "rimraf ./dist && mkdir dist",
"prebuild": "yarn clean",
}
}
and yarn prebuild to run the script command.
The syntax allows one to omit the run argument.
