# Exec CLI command reference

**CLI output**

```sh
USAGE
  $ sanity exec SCRIPT [--mock-browser-env] [--with-user-token]

ARGUMENTS
  SCRIPT  Path to the script to execute

FLAGS
      --mock-browser-env  Mock a browser environment with jsdom
      --with-user-token   Include your auth token in getCliClient()

DESCRIPTION
  Executes a script within the Sanity Studio context

EXAMPLES
  Run the script at some/script.js in Sanity context

    $ sanity exec some/script.js

  Run the script at migrations/fullname.ts and configure `getCliClient()` from `sanity/cli` to include the current user's token

    $ sanity exec migrations/fullname.ts --with-user-token

  Run the script at scripts/browserScript.js in a mock browser environment

    $ sanity exec scripts/browserScript.js --mock-browser-env

  Pass arbitrary arguments to scripts by separating them with a `--`. Arguments are available in `process.argv` as they would in regular node scripts (eg the following command would yield a `process.argv` of: `['/path/to/node', '/path/to/myscript.js', '--dry-run', 'positional-argument']`)

    $ sanity exec --mock-browser-env myscript.js -- --dry-run positional-argument
