>首先感谢您的帮助，我有一个简单的bash脚本，他正在阅读服务器列表，命令列表和回滚命令列表，脚本工作正常，
但我的问题与日志有关，因此我想将控制台上的输出记录到日志文件中。 问题是当我打开日志文件时，我可以看到带有日志的菜单，任何帮助从日志文件中排除菜单，
使用 导出日志 IM
exec > >(tee -a ${log_file} )
exec 2> >(tee -a ${log_file} >&2)
执行脚本(代码如下(后，我看到的是：
**************************************************************
test script
**************************************************************
** 1) Test ip connectivity for all the servers. **
** 2) Display the default config before apply the hardening.**
** 3) Executing the hardening changes. **
** 4) Display the new values after the hardening applied. **
** 5) Rollback to the default config. **
**************************************************************
Please enter a menu option and enter or x to exit. 3
Option 3 : Executing config.
当我检查日志时，我可以看到一个很好的日志，但菜单:(

[root@host1 newscript]# cat Hardening_log.txt
