ansible diff игнорирует порядок строк

Question

Команда diff, введенная непосредственно из Ubuntu, обеспечивает ожидаемый результат, но при вводе через playbook выдает следующие ошибки:

ubuntu@ubuntu:~$ diff <(sort CSR1_route.txt) <(sort CSR2_route.txt) >> delta1.txt ubuntu@ubuntu:~$ more delta1.txt 13c13 < O        2.2.2.2 [110/2] via 192.168.255.134, 01:36:31, GigabitEthernet1
---
> O        1.2.2.2 [110/2] via 192.168.255.134, 01:36:31, GigabitEthernet1
