htaccess help catch all 301

I have been looking at the webmaster tools 开发者_如何学JAVAthis morning, and I have quite a few crawl errors, and old SEO agency seems to have done to some shoddy work to build up my links into the site, but this is resulting in crawl errors,

I would like to 301 redirect any URLS that have /old in them back to my homepage, is that at all possible?

something like

Redirect permanent */old http://<yourhomepage>
