HI all,

I am actually look at ways to restart a process if it hangs.
The line I highlighted in red sometime work, it will continue to the next line.
If it doesn't work,I would expect a way to restart that line first before proceeding to the next line.
Hope you can advise.

Code:
while read ip; do
    echo -e "${BLUE}[+]${RESET} Scanning $ip for $proto ports..."

    # unicornscan identifies all open TCP ports
    if [[ $proto == "tcp" || $proto == "all" ]]; then 
        echo -e "${BLUE}[+]${RESET} Obtaining all open TCP ports using unicornscan..."
        echo -e "${BLUE}[+]${RESET} unicornscan -i ${iface} -r20000 -mT ${ip}:a -l ${log_dir}/udir/${ip}-tcp.txt"
        unicornscan -i ${iface} -mT ${ip}:a  -r20000 -l ${log_dir}/udir/${ip}-tcp.txt
        ports=$(cat "${log_dir}/udir/${ip}-tcp.txt" | grep open | cut -d"[" -f2 | cut -d"]" -f1 | sed 's/ //g' | tr '\n' ',')
        if [[ ! -z $ports ]]; then 
            # nmap follows up
            echo -e "${GREEN}[*]${RESET} TCP ports for nmap to scan: $ports"
            echo -e "${BLUE}[+]${RESET} nmap -e ${iface} ${nmap_opt} -oA ${log_dir}/ndir/${ip}-tcp -p ${ports} ${ip}"
            nmap -e ${iface} ${nmap_opt} -oA ${log_dir}/ndir/${ip}-tcp -p ${ports} ${ip}
        else
            echo -e "${RED}[!]${RESET} No TCP ports found"
        fi
    fi

NAME

       amanda-scripts - Configuring and using the Script API

DESCRIPTION

       The Script API is a flexible system for invoking user-supplied scripts at various points in the execution of Amanda. This manual page
       describes the operation and configuration of the API. For help writing Script API scripts, see http://wiki.zmanda.com/index.php/Script_API.

SCRIPTS

       This section lists the scripts included with Amanda, see the individual man page for instructions on using them. For complete How-To
       information, consult the Amanda wiki at http://wiki.zmanda.com.

       o   amzfs-snapshot(8), - create/destroy zfs snapshot.

       o   script-email(8), - send email.

       Script properties work just like application properties: they are insensitive to case, and - (dash) and _ (underscore) may be used
       interchangeably.

SCRIPTS OUTPUT PROPERTY

       A pre-dle-amcheck, pre-dle-estimate or pre-dle-backup executed on the client can output property on stdout that are sent to the
       application. If the output line matches "PROPERTY str1 str2", Amanda sets a property called "str1" by the value of "str2", that property is
       sent to the application.
