Here is a crude shell script that should accomplish what you want. It
is crude because it will break if you run it around midnight and does
very limited parameter and no error checking. But if you pass it the
time in the format HH:MM:SS followed by the command you want to run,
it will start the command at the specified time.
if [ "$(date +%T)" < "$start" ]; then
echo "It's already after $start"
while [ "$(date +%T)" != "$start" ]; do
echo "Starting command at $start"
