Anyway, it looks like tcsh has a lot more than bash in this area. I
may just give tcsh another try. On the other hand, it's not that
inconvenient to not be able to get this automatically in bash. I
would just have to remember to use the 'time' command when I really
want to time something. :-)
zsh's preexec() function might help you out here. It runs after the
command has been read by the shell but just before it executes the
command. In fact, I just tried it at my shell and I can make it print
the date before each following command:
revolver: /usr % preexec () { date }
Then:
revolver: /usr % ls

If you grew up on tcsh, you might like zsh a lot -- virtually all of the
features of tcsh, with Bourne-shell syntax. I learned tcsh first, and
then switched to zsh and never looked back.
