I could not get it to work until I changed the single quotes in the last -e 
expression to double quotes.  (This either interactively under csh or as a 
script under sh).  BTW, using `date +%s` and with an additional minor change to 
make the numbers continue to line up ... Oh!  This will not fix mis-alignments 
on days when it is not the end of the week, I don't think ... anyway.

cal | awk 'NR>1' | sed -e 's/   /    /g' -e 's/[^ ] /& /g' -e 's/..*/  &/' -e 
"s/\ `date +%d`/\[`date +%d`\]/"

Gives
$ sh newcal.sh
  Su  Mo  Tu  We  Th  Fr  Sa
                   1   2   3
   4   5   6   7   8   9 [10]
  11  12  13  14  15  16  17
  18  19  20  21  22  23  24
  25  26  27  28  29  30  31

Now, if you had a space character at the end of each line, you could do 
something like ...

cal | awk 'NR>1' | sed -e 's/   /    /g' -e 's/[^ ] /& /g' -e 's/..*/  &/' -e 
"s/\ `date +%d`\ /\[`date +%d`\]/"

And then it would replace (underscore is space) "_8_" with "[8]" so it would 
always line up.  You can't do that without the space at the end of the line 
because the trailing numbers look like this "_17" not "_17_".  But, fix that, 
and you can use the above.  That is left as an exercise for the reader.
