    How to check all the currently running services in Linux


    To find the status of any single service
    # service vsftpd status
    vsftpd (pid 5909) is running...

    To get the status of all the running services
    # service --status-all | grep running
    acpid (pid 5310) is running...
    atd (pid  6528) is running...
    auditd (pid  5012) is running...
    Avahi daemon is not running
    Avahi DNS daemon is not running
    The Pegasus CIM Listener is running.
    The Pegasus CIM Object Manager is running.
    crond (pid  6242) is running...
    dcerpcd (pid  5177) is running...
    eventlogd (pid  5223) is running...

    In case you don't use grep you will be able to see all the services on your machine
    # service --status-all
    NetworkManager is
    stopped
    acpid (pid 5310) is running...
    anacron is stopped
    atd (pid  6528) is running...
    auditd (pid  5012) is running...
    automount is stopped
    Avahi daemon is not running
    Avahi DNS daemon is not running
    hcid is stopped
    sdpd is stopped

    You can also check the active ports along with their services using
    # netstat -ntlp
    Active Internet connections (only servers)
