My original message is at the bottom of this email. Thank you to all who
responded. The list of all these kind people includes:

Tim Gallagher
Shiv AgarWal
Nikola Milutinovic
Lars Bro
Alan Davis
Roger Leaonard
Declan Lennon
Dr.Tom Blinn

Two basic answers were offered, and they both work. I am quoting
alan_at_nabeth.cxo.dec.com:

1. The ps(1) command with suitable options (aux in BSD mode) will print the
resident set size (the RSS field), which is probably the closest
approximation you'll get to per-process physical memory use.

2. vmstat has options that will show various summaries of how kernel memory
is used. The -P option may be the most useful.

Other interesting option sets for ps that were offered are:

ps axv
ps auxww (in particular the %MEM column)
ps -A -o pid,pmem,rss,command

Lars also mentioned the VSZ column of ps as that showing the size of the
virtual address space.

Thanks again,

  Dear Tru64-Unix Managers,

  I would like to know if there is a command that can actually tell me how
much physical memory is currently allocated to processes.

  Thanks in advance,
