Memory usage per process

How can one see the output of the memory usage per process in Windows using bash (Git bash) and without any additional tools installation?

I read about top command but there is no such thing in the default version of bash. Also, I have read about ps but it does not give the memory usage at all as in some examples I have seen (maybe some version has been changed).

Since Linux processes in WSL run in a container (conceptually similar to Docker), they can only see processes in the same container, nothing else.

You can see the virtual and resident size of processes in WSL by issuing the following command:

ps -eHww -o uid,pid,ppid,psr,vsz,rss,stime,time,cmd

Outputs:

max@supernova:~$ ps -eHww -o uid,pid,ppid,psr,vsz,rss,stime,time,cmd
