Exit a Script On Error

bash, exit, shell

Solution

Are you looking for `exit`?

This is the best bash guide around. http://tldp.org/LDP/abs/html/

In context:

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 1>&2
    exit 1 # terminate and indicate error
fi

...

Problem

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