We don't support shell expansions in the -c argument.  If you want to do
the above, one easy way from ksh or bash is this:

dtrace -o /dev/fd/3 -s dscript.d -c date 3>&1 1>out 2>err 

which says:

dtrace's stdout goes to fd 3, which is dup'd from the current stdout
dtrace's stderr goes to 'err'

date's stdout is modified to 'out'
date's stderr is modified to 'err'

Or you can use -o to specify a particular output file.
