The command "at ${hh:mm} -m" is used to schedule a command or job to run at a specific time.

Here's a breakdown of the components:

"at": This is the command itself that is used to schedule tasks.
"${hh:mm}": This represents the time at which you want the command or job to run. You need to replace "${hh:mm}" with the desired hour and minute in 24-hour format. For example, if you want the job to run at 10:30, you would write "10:30" in place of "${hh:mm}".
"-m": This parameter is used to send an email notification to the user once the job is completed. It ensures that the user receives an email with the output/results of the command.

By using this command, you can schedule tasks or jobs to automatically run at specific times, and be notified via email when they are completed.
