I want to substitute all the colons in a command line to, say, spaces in
/bin/tcsh.  However,

      !!:gs/:/ /

only changes the first colon.  Is this a bug?  Does anyone know how to get
around this?  While I've got your attention, I should also ask if anyone
has a better way to do the following in tcsh:

     echo "set today = (`date`)" > /tmp/.date
     source -h /tmp/.date
     !set:s/:/ /:s/:/ /

(note the kludge because the global sub doesn't work) but without calling
sed or writing a C program.

Try:  set today = (`date | tr ':' ' '`)

Try :

	% eval `date '+set today=(%a %h %d %H %M %S 19%y)'`
	% echo $today
	Thu Sep 06 18 13 08 1990

The only problem is that you don't get the "CDT" string before the year.
If you can live without it, your problem is solved.
