Jenkinsfile add if else script?

Question

i would like to integrate a simple if else script to my Jenkinsfile but i have a little problem :

My Bash Script :

#!/bin/bash
if [ -e /root/test/*.php ];then
echo "Found file"
else
echo "Did not find file"
fi

The Script work very well but if i try to integrate in a stage they dont function :

        stage('Test') {
        steps {
            script {
                    if [ -e "/root/test/*.php" ];then
                        echo found
                    else 
                        echo not found
                }
            }
    }

Pipeline's script step expects Groovy script, not Bash script - https://jenkins.io/doc/book/pipeline/syntax/#script

Instead of using script step you can use sh step which is designed to execute shell scripts. Something like this (this is just an example):

stage('Test') {
    steps {
        sh(returnStdout: true, script: '''#!/bin/bash
            if [ -e /root/test/*.php ];then
            echo "Found file"
            else
            echo "Did not find file"
            fi
        '''.stripIndent())
    }
}
