Exclude the current post in the get posts code

What if i want to exclude the current post in the get posts code?

$postslist = get_posts(‘numberposts=1000&order=ASC&exclude=….&orderby=date&cat=’ . $cat_id);

In which case … should be the current post ID.

The current post ID template tag is; the_ID() I thought.

I would very much appericiate it when someone could explain how it works, because i dont want to bother you every time..

Thanks in advance!
