Multics (begun 1967) preceded Unix (begun 1969) and influenced it very much. Here is a list of Multics commands:

In Multics, cwd was change_wdir, like Unix cd. There was a Multics cd command but it meant create_dir.

CTSS (begun 1961) influenced Multics, Unix and pretty much every other timesharing system. Here are some of its commands:

In CTSS each user had only one directory so there was no cd command. But you can see the ancestors of some other Unix commands in this list.
