Please help to reset BOLD formatting for xTerm colors in bash script

I run a script that has some primitive formatting. After executing the script, the entire next output becomes bold (but not green). It doesn’t happen in a normal terminal. How to completely reset all formatting after some commands?

Test environment

• Jenkins Version: 2.150.2
• AnsiColor Version: 0.6.1
• Hostsystem: Ubuntu 16.04.4 LTS

Expected behavior

After closing ansiColor('xterm') { ... } all further formatting should be reset to normal.

Actual behavior

Everything is bold after ansiColor is finished its work.

Steps to reproduce the behavior

pipeline {
    agent { label 'worker' }
    stages {
        stage('colors') {
            steps {
                script {
                    ansiColor('xterm') {
                        writeFile file: 'script.sh', text: '''#!/usr/bin/env bash

RED="\\e[31m"
GREEN="\\e[32m"
BOLD="\\e[1m"
NORMAL="\\e[0m"

printf "${GREEN}${BOLD}"
printf "All updated ...\\n"
printf "${NORMAL}"
'''
                        sh '''
cat script.sh && chmod +x script.sh
'''
                        sh './script.sh'
                    }
                    println 'Why am I so bold?'
                }
            }
        }
    }
}

UP: The same happens if the plugin used inside options section.

options {
        ansiColor('xterm')
    }

Ok, let’s close this. If someone find the same problem and can isolate it, maybe he will reopen this or create a new ticket.

Thank you!

then using chef-solo in the terminal means that all subsequent terminal output would be colored, right

No, locally it works fine. Only in Jenkins everything is colored after some of receipts executed on ec2 instances using chef-solo. I don’t know when and why it happens.
