java -jar 到 springboot jar 返回 PID 而不是退出代码

Question

I am trying to execute an sh which has a java -jar and make it return the exit code, but instead it is retrieving me the PID assigned to that process

PROCESO="java -Xmx2048m -jar xyz.jar"
echo $?

returns the PID

How can i make it return exit code instead?

Answer 1

PROCESO="java -Xmx2048m -jar xyz.jar"

is an assignment of the string "java -Xmx2048m -jar xyz.jar" to PROCESO .

If you want to run java, do it like this:

java -Xmx2048m -jar xyz.jar
echo $?

This executes xyz.jar and echos the exit code.
