Years ago System 5.4 acquired a 'truss' program that looked at it's /proc
file system (similar to strace - which probably should have been called
truss) - & I think that Solaris has it as well. HPUX, AIX don't since
they aren't 5.4 based; but I must admit that I am getting Unix rusty since
it is getting to be some time since I have done serious Unix hacking as Linux
is much better for what I do.

AFIR 5.4 /proc inspired the Linux /proc which is light years ahead.
