Shell Programming and Scripting

I want to send 5 ping to 3 web site

result:

1- www.google.com UP
2- www.yahoo.com UP
3- www.myserver.com DOWN

If myserver.com is down I want to 10 ping all of them again (To avoid errors resulting)

result:

1- www.google.com UP
2- www.yahoo.com UP
3- www.myserver.com DOWN

I want to run a curl command.


If first ping result is:

1- www.google.com DOWN
2- www.yahoo.com UP
3- www.myserver.com DOWN

I don't want to run a curl command.

#!/bin/bash
function checksites {
    SEND=$1
    shift
    while [ $# -gt 0 ]
    do
        ping -n $SEND $1 2>&1 | grep -q "[ (]0%"
        if [ $? -eq 0 ]
        then
            printf " UP"
        else
            printf " DOWN"
        fi
        shift
    done
}
CHECK=( www.google.com www.yahoo.com www.myserver.com )
RESULT=( $(checksites 5 ${CHECK[@]}) )

[ "${RESULT[2]}" = "DOWN" ] && RESULT=( $(checksites 10 ${CHECK[@]}) )

if [ "${RESULT[*]}" = "DOWN UP DOWN" ]
then
    echo "Run your curl command here"
fi

if [ "${RESULT[*]}" = "UP UP DOWN" ]
then     
    echo "Run your OTHER curl command here"
fi

#!/bin/bash
function checksites {
    SEND=$1
    shift
    while [ $# -gt 0 ]
    do
        ping -n $SEND $1 2>&1 | grep -q "[ (]0%"
        if [ $? -eq 0 ]
        then
            printf " UP"
        else
            printf " DOWN"
        fi
        shift
    done
}
CHECK=( www.google.com www.yahoo.com www.ZB37NNRHHS4Fmyserver.com )
RESULT=( $(checksites 5 ${CHECK[@]}) )

[ "${RESULT[2]}" = "DOWN" ] && RESULT=( $(checksites 10 ${CHECK[@]}) )

if [ "${RESULT[*]}" = "UP UP DOWN" ]
then     
    curl -o /root/100mb.test "http://cachefly.cachefly.net/100mb.test"
