错误退出脚本 [英] Exit a Script On Error

问题描述

我正在构建具有这样的if功能的Shell脚本:

I'm building a Shell Script that has a if function like this one:

if jarsigner -verbose -keystore $keyst -keystore $pass $jar_file $kalias
then
    echo $jar_file signed sucessfully
else
    echo ERROR: Failed to sign $jar_file. Please recheck the variables
fi

...

我希望在显示错误消息后完成脚本的执行.我该怎么办?

I want the execution of the script to finish after displaying the error message. How I can do this?
