Seems to work for me ( $() is just another name for `` that nests a
bit nicer):


% echo 20030705 > zorch
% if [[ $( date +%Y%m%d ) -eq $( cat zorch ) ]] ; then echo match ;
else echo no match ; fi
no match
% date +%Y%m%d > zorch
% cat zorch
20030707
% !if
if [[ $( date +%Y%m%d ) -eq $( cat zorch ) ]] ; then echo match ; else
echo no match ; fi
match
% echo $BASH_VERSION
2.05b.0(1)-release


Works just fine in zsh as well.
