例如，如何创建一个简单的Shell脚本，请求用户进行简单输入，然后只运行与预定义选项关联的命令Linux 交互式Shell脚本,linux,shell,user-input,user-interaction,Linux,Shell,User Input,User Interaction,例如，如何创建一个简单的Shell脚本，请求用户进行简单输入，然后只运行与预定义选项关联的命令 IF "ON" Backup Server ELSEIF "OFF" Delete Backups ELSEIF "GREY" Send Backups ENDIF 您可以通过read获取用户的输入，并且可以使用案例。。。esac阻止执行不同的操作 Read将变量的名称作为其参数，并将其值存储到该变量中 read foo 将从用户处接收vaue并将其存储在$foo中 要提示用户输入，您需要使用ec
IF "ON"
Backup Server
ELSEIF "OFF"
Delete Backups
ELSEIF "GREY"
Send Backups

大家好，这里有一个简单的例子如何做到这一点
while true; do
read -p 'do you want to continue "y" or "n": ' yn
case $yn in
[Yy]* ) echo 'this program continue '; break;;
[Nn]* ) exit;;
* ) echo 'Please answer yes or no: ';;
esac
done
while true; do
read -p 'press "c" to quit this program: ' c
case $c in
[Cc]* ) exit;;
* ) echo 'for quit this program press "c": ' ;;
esac
done
对于源代码，请单击此处您好，这里有一个简单的示例
while true; do
read -p 'do you want to continue "y" or "n": ' yn
case $yn in
[Yy]* ) echo 'this program continue '; break;;
[Nn]* ) exit;;
* ) echo 'Please answer yes or no: ';;
esac
done
while true; do
read -p 'press "c" to quit this program: ' c
case $c in
[Cc]* ) exit;;
* ) echo 'for quit this program press "c": ' ;;
esac
done
对于源代码，请单击此处是否需要该\c？我需要在某个地方定义选项吗？
'\c'-n'\c'-n
