Exit a Script On Error

Question

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
            


        

Answer 1

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
