echo "midnight" | at 00:00 2>/dev/null
Esta pergunta já tem uma resposta aqui:
Eu estava usando um comando at no meu perfil bash para fazer a hora do dia a cada hora para me lembrar da hora, mas agora, quando abro a linha de comando, aparece um aviso irritante como esse:

O comando que estou tentando executar é um exemplo:
echo "midnight" | at 00:00
Como posso remover esses avisos?
Notas: Não é como a pergunta; "Por que at me avisa que os comandos serão executados usando / bin / sh? E se eu quiser um shell diferente?" porque, eu não quero saber porque eu quero saber como me livrar do aviso e eu não quero saber nada sobre o shell.
