You need 'csh -i'. But it's not very funny to work if you have no tty accessed
and therefore NO job control in the shell.

lastcomm DOES catch you!

I don't know the command 'top', maybe that's what we call 'lastcomm' which
shows the last commands which had been executed. But, if you use 'top' the way
we use 'lastcomm', what does your 'lastcom' with one 'm' at the end do?

Anyway, 'ps -auxww' will show the arguments you use. Note the two 'w's.
(Under 4.x bsd and Ultrix 3.0)

My question to the original poster: Why do you want to hide your commands. Are
you going to crack the system...?

Cheers, Elmar
