Trash file inaccessible through Terminal?

Having come from a Linux environment, I am accustomed to using the command line, as in MacOS's "Terminal". In particular, I know about permissions, "sudo" and such. But I am unable to perform any operations whatsoever via the command line on the .Trash file in my home directory. (I do have admin privileges on the machine.) I can "ls -al" my home directory... However, I _can_ see (and copy, deleted, etc.) the contents of my .Trash file via Finder, and could apparently manipulate its permissions. But, seemingly, nothing I can do with finder makes .Trash accessible via Terminal. Can anyone explain?
