Variable traverse`Const`

traverse: {
forFile: (dir: string, file: string) => Promise<Optional<string>>;
forFileSync: (dir: string, file: string) => Optional<string>;
} = ...

These methods were moved from the deprecated 'fs' module in v2 and are only used in sfdx-core above

They were migrated into the 'traverse' constant in order to stub them in unit tests

forFile: (dir: string, file: string) => Promise<Optional<string>>

Searches a file path in an ascending manner (until reaching the filesystem root) for the first occurrence a specific file name. Resolves with the directory path containing the located file, or null if the file was not found.
forFileSync: (dir: string, file: string) => Optional<string>

Searches a file path synchronously in an ascending manner (until reaching the filesystem root) for the first occurrence a specific file name. Resolves with the directory path containing the located file, or null if the file was not found.
