You could use ps(1). Inside the shell, you could run:

  $ ps -q $$ -o comm,rss,vsize

where `$$` is a reference to the `$` variable, which contains the=20
PID of that shell. Outside that shell, replace `$$` by the PID of=20
the relevant shell as found by other means (e.g. via pgrep(1)):

  $ ps -q 1234 -o comm,rss,vsize

Here's an article explaining 'memory usage' as represented by=20
vsize/vsz and rss:
