Make build UNSTABLE if text found in console log using jenkinsfile (jenkins pipeline)

Question

I am trying to login into an instance and check if the file test.txt is not empty, then echo .. make build unstable using the jenkins pipeline (jenkinsfile)But that's not working. I have this:

post {
        always {
          sh "ssh ubuntu@$Ip 'if [ -s test.txt ] ; then echo some text && cat test.txt'"
        currentBuild.result = 'UNSTABLE'
          }
        }

Instead of doing above, can I parse through the console log of the latest build to find something eg: some text and if that's found I want to make the build unstable

You need to return standard out from the script:

String stdOut = sh returnStdout: true, script: "ssh ubuntu@$Ip 'if [ -s test.txt ] ; then echo some text && cat test.txt'"

if (stdOut == "") {
   currentBuild.status = 'UNSTABLE'
}

Or, you could use returnStatus to return the exit code of the script. The documentation for the sh step can be found here
