перенаправить bash вывод скрипта в файл журнала, исключая меню

/ 20 июня 2020

сначала спасибо за помощь очень ценю, у меня есть сценарий bash простой, он читает список серверов, список команд и список команд отката, скрипт работает нормально,

но моя проблема связана с журналом, поэтому я хочу записывать вывод на консоли в файл журнала. проблема в том, что когда я открываю файл журнала, я вижу там меню с журналом, любую помощь для исключения меню из файла журнала,

для экспорта журнала с использованием 

exec > >(tee -a ${log_file} )
exec 2> >(tee -a ${log_file} >&2)

после выполнения сценария (код ниже) вот что я вижу: 

**************************************************************

** 4) Display the new values after the hardening applied.   **

Option 3 : Executing config.

Когда я проверяю журнал, я вижу хороший журнал, но с меню: (

[root@host1 newscript]# 
[root@host1 newscript]# 
[root@host1 newscript]# cat Hardening_log.txt

Возможно дублировать начальный стандартный вывод в другой дескриптор файла (например, 3) и отправить меню на этот дескриптор. После настройки (exec 3>&1) добавьте> & 3 к любой команде, вывод которой НЕ должен go в файл журнала. 

...

  # Keep handle to original stdout on fd 3
exec 3>&1
  # capture stdout/stderr to log file
exec > >(tee -a ${log_file} )
exec 2> >(tee -a ${log_file} >&2)

...
function show_menu {
}

...
  # Output the clear seq and the menu to terminal only
clear >&3
show_menu >&3

  # Rest of the code
while [ $opt != '' ] 
...
done
