    In a bash script I am starting openvpn as a client like this:

    #!/bin/bash
    conf_file=/etc/openvpn/blahblah.conf
    openvpn_pid_file="/var/run/openvpn-client/ovpnc.pid"
    command_line="/usr/bin/openvpn --config $conf_file --daemon"
    $command_line
    openvpn_pid=$!
    echo "openvpn_pid=$openvpn_pid"
    echo $openvpn_pid >> "$openvpn_pid_file"


    After a successful start of openvpn, my variable openvpn_pid is empty and my openvpn_pid_file is empty. However, pgrep openvpn will give me the PID. Why am I not getting that PID in my script? What should I change in order to get the correct PID in my variable and ultimately into the openvpn_pid_file?

    This is all on Arch Linux.
