Question

我正在尝试运行一个实用程序（nco_confpack），它直接在命令行上使用时效果很好。但是当我在shell脚本中的while循环中使用相同的实用程序时，实用程序进入无限循环而不接受任何输入。如何避免实用程序的无限循环？以下是工作正常的代码片段

bash-3.2$ $OMNIHOME/bin/nco_confpack -import -server SERVERA -user root -password XXXXX-select Class.list -package Class.jar
*********************************************************************
*                          W A R N I N G                            *
*                                                                   *
* This action may overwrite configuration currently in your system. *

* It is recommended that a backup is made of the current data       *

*                                                                   *

Do you want to continue (y/n) [N]? y
bash-3.2$

但是，当在while循环中放置相同的实用程序时，是否要继续（y / n）消息进入无限循环而不接受任何输入

bash-3.2$ ./classInstall.sh
Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? Do you want to continue (y/n) [N]? ^C

我在这里做错了什么？该实用程序有问题，还是我必须明确提及脚本中的内容？

该脚本包含相同的命令，只是它在有限的while循环下运行。

bash-3.2$vi classInstall.sh
cat $1 | while read theLine
do
$OMNIHOME/bin/nco_confpack -import -server SERVERA -user root -password XXXXX-select Class.list -package Class.jar
done

$ 1只包含两个条目，因此循环，命令只能运行两次

我不完全确定为什么 while循环通过换行符为您的实用程序提供服务，但您可以通过提供预期的＆＃39; y＆＃39;来解决问题。对自己的实用程序：

cat $1 | while read theLine
do
    echo y | $OMNIHOME/bin/nco_confpack -import -server SERVERA -user root -password XXXXX-select Class.list -package Class.jar
done

如何在shell脚本中的循环中执行输入请求实用程序？
