usando “at” para executar o script python em um horário específico que não funciona

Question

Estou tentando executar este script às 7h da manhã, todas as manhãs.

O comando que estou usando no teste é:

echo "python checker.py" | at 8:40 PM

Qual falha.

Quando eu verifico o at -c log, recebo a seguinte mensagem:

root@black:~/Documents/projects/pytests/campsite-checker# at -c 23
#!/bin/sh
# atrun uid=0 gid=0
# mail root 0
umask 22

python checker.py

Depois de muitos trabalhos importantes do Google, ainda não sei o que isso significa?

    

Answer 1

O que você está vendo é o ambiente de execução que está sendo configurado; não é uma mensagem de erro.

Se houvesse mensagens de erro, elas teriam sido enviadas para o root. Verifique seu e-mail root?
