I was using an at command in my bash profile to echo the time of day at every hour to remind me of the time but now when I open up the command line it flashes a lot of annoying warning like these:

The command I am trying to run is example:

echo "midnight" | at 00:00

How can I remove these warnings?

Notes: It is not like the question; "Why does at warn me that commands will be executed using /bin/sh? What if I want a different shell?" because, I don't want know why I want to know how to get rid of warning and I don't want to know anything anything about the shell.

    FYI: Sounds like you want cron—that's the normal way to run a command every hour. – derobert Aug 31 '16 at 16:25
  • Except for that the output I want is different every hour. Example: – Nathan Hill Sep 01 '16 at 01:47
  • midnight, 7 o'clock, ect. – Nathan Hill Sep 01 '16 at 01:48
  • I have had one answer and it worked so unless you have a better answer or explanation of why that worked then please stop commenting. – Nathan Hill Sep 01 '16 at 01:50
  • also please stop marking this as a duplicate because I have looked at the other question and it asking how to use a different shell to get rid of the warning message where as I just want to change the command so it doesn't show the warning and the answer I got that worked was not on the other question. – Nathan Hill Sep 01 '16 at 01:57
