What arguments does your "top" accept?
-n 1 (one iteration only) will be helpful.
-b (batch mode) might be.
-u username or -U username (TFM) can save some post-processing.
You might also want a way to override .toprc, if your version supports
that. The aim is to get a consistent output format, of course.
When you've got the right number included in the output, either some
combination of grep and
tr -s ' ' | cut -d ' ' -f 5 (for suitable values of 5)
or awk to better confine the grep pattern matches should allow you to
isolate the number you want.
Whether "top" is the right tool is a separate question; if you're
happy that it is, then the above should allow you to use it.
All the best,
