Well, this is very interesting. I am glad to hear you based the current
ps_status code on sendmail, which I think is the perfect way to go.
I seem to remember the Solaris manual page stating it doesn't update the
ps display, but I may be mixing that up with something else. I agree
/usr/bin/ps is the better option, if we can get it working. Most people
will not remember to use /usr/ucb/ps.
I just uploaded a 0.34 version that allows the 'ps' command to be
customized by editing the script.
