Sometimes we want to upgrade only some modules. You can control it by passing an

argument to a `--reload` flag.

To reload everything
|

`--reload`

To reload all standard modules
|

|

`--reload=https://deno.land/std`
|

To reload specific modules (in this example - colors and file system utils) use
|
||||
a comma to separate URLs
|
||||
|
||||
`--reload=https://deno.land/std/fs/utils.ts,https://deno.land/std/fmt/colors.ts`
