function Deno.chmod
chmod(path: string | URL,mode: number,): Promise<void>
Changes the permission of a specific file/directory of specified path.
Ignores the process's umask.
```ts
await Deno.chmod("/path/to/file", 0o666);
```
The mode is a sequence of 3 octal numbers. The first/left-most number
specifies the permissions for the owner. The second number specifies the
permissions for the group. The last/right-most number specifies the
permissions for others. For example, with a mode of 0o764, the owner (7)
can read/write/execute, the group (6) can read/write and everyone else (4)
can read only.
