Bash script to output function result

Question

I have a bash shell script executed by Jenkins / Hudson. For some reason when I create a function, the output of that function is not logged back to the console. This is an example of my code:

EDIT!!! - this culprit here is SSH... Is there a way to force its output back to console?

perform_task()
{
   ssh [email protected] pwd
}

echo "Starting a task";
perform_task || { echo "The Task Failed"; exit 1; } 

The output in the console is:

"Starting a task"

if I move the commands outside of the function, I can see their output.

Help on this would be greatly appreciated!

Answer 1

I partially solved the problem by getting the script to echo the command:

#!/bin/bash -ex

This still hides the output of that command, but at least I have insights about what's being run

Answer 2

I just copied your function, added #!/bin/bash -e to the beginning of and pasted it into the "Execute Shell" of Jenkins.

It worked fine!

Is your bash executable actually located at /bin? What OS are you running the script on?

Building remotely on slave_1
[test] $ /bin/bash -xe /tmp/hudson1206345540964396738.sh
+ echo 'Starting a task'
Starting a task
+ perform_task
+ ssh slave_2 pwd
/home/jenkins
Finished: SUCCESS
