Difference between /usr/sbin/ps & /usr/ucb/ps command
The command that is equivalent to /usr/usb/ps -axu is "ps -aef"
/usr/ucb/ps is BSD
/usr/sbin/ps is SVR4
/usr/ucb/ps -www ==as wide as possible, this over comes the 80 column restriction that is seen in normal ps -ef command.
To see which executable is being run by a process, '/usr/ucb/ps auxwww' can be used. it shows you the exact command that invoked all the processes you see via 'ps'.
