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:warning: commands will be executed using /bin/shjob 241 at Thu Sep  1 00:00:00 2016warning: commands will be executed using /bin/shjob 242 at Thu Sep  1 01:00:00 2016warning: commands will be executed using /bin/shjob 243 at Thu Sep  1 02:00:00 2016warning: commands will be executed using /bin/shjob 244 at Thu Sep  1 03:00:00 2016warning: commands will be executed using /bin/shjob 245 at Thu Sep  1 04:00:00 2016warning: commands will be executed using /bin/shjob 246 at Thu Sep  1 05:00:00 2016warning: commands will be executed using /bin/shjob 247 at Thu Sep  1 06:00:00 2016warning: commands will be executed using /bin/shjob 248 at Thu Sep  1 07:00:00 2016warning: commands will be executed using /bin/shjob 249 at Thu Sep  1 08:00:00 2016warning: commands will be executed using /bin/shjob 250 at Thu Sep  1 09:00:00 2016warning: commands will be executed using /bin/shjob 251 at Wed Aug 31 10:00:00 2016warning: commands will be executed using /bin/shjob 252 at Wed Aug 31 11:00:00 2016warning: commands will be executed using /bin/shjob 253 at Wed Aug 31 12:00:00 2016warning: commands will be executed using /bin/shjob 254 at Wed Aug 31 13:00:00 2016warning: commands will be executed using /bin/shjob 255 at Wed Aug 31 14:00:00 2016warning: commands will be executed using /bin/shjob 256 at Wed Aug 31 15:00:00 2016warning: commands will be executed using /bin/shjob 257 at Wed Aug 31 16:00:00 2016warning: commands will be executed using /bin/shjob 258 at Wed Aug 31 17:00:00 2016warning: commands will be executed using /bin/shjob 259 at Wed Aug 31 18:00:00 2016warning: commands will be executed using /bin/shjob 260 at Wed Aug 31 19:00:00 2016warning: commands will be executed using /bin/shjob 261 at Wed Aug 31 20:00:00 2016warning: commands will be executed using /bin/shjob 262 at Wed Aug 31 21:00:00 2016warning: commands will be executed using /bin/shjob 263 at Wed Aug 31 22:00:00 2016warning: commands will be executed using /bin/shjob 264 at Wed Aug 31 23:00:00 2016The command I am trying to run is example:echo midnight | at 00:00How 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.
Removing the warning message that pops up when using an at command
command line;echo;at
echo midnight | at 00:00 2>/dev/null
