These two commands are equivalent...

/usr/ucb/ps auxwww

USER       PID %CPU %MEM   SZ  RSS TT       S    START  TIME COMMAND

/usr/bin/ps -A -o user,pid,pcpu,pmem,vsz,rss,tty,s,stime,time,args

    USER   PID %CPU %MEM  VSZ  RSS TT      S    STIME        TIME COMMAND

I've verified that SZ and VSZ are the same by comparing 
output...however, there is a bit of a shortcoming with the berkeley 
ps...it runs %MEM, SZ and RSS together.  It looks like the percent 
memory is consistently 3 chars wide (%1.1f)...I wish I could say the 
same about SZ and RSS...
