why go outside of perl to invoke the 'write to stdout' of 'echo'
and then redirect it to a file???
in the shell the command would have looked like
echo "Warning: `date` some text" > $log
hence you would want something like:
[jeeves:~] drieux% perl -e 'my $word_up = `echo -n "Warning \`date\` some
text"`;\
print "<< $word_up>>\n";'
as others have noted you may wish to look at doing
this IN perl with perl's time functions
cf: perldoc localtime
you may also want to think in terms of a 'log_me'
function that knows how to hide that....
