Shell Programming and Scripting

Hi
I wrote this script with the help of you guyz.My next challenge is to increment the port using single file.So far iam using this code to increment hp1 and hp2 .To increment port numbers, iam using two different files (.default_port_hp1 and .default_port_hp2).The challenge for me is to use single file and increment the ports.


-------------
echo -n "Enter hp1 port: "
read hp1
if [ -z $hp1 ]
then

default_port_file=.default_port_hp1
default_port_value=80

get_default_port()
{
if [ -f $default_port_file ]
then
default_port=$(<$default_port_file)
else
default_port=$default_port_value
fi
}
set_default_port() {
if [[ $1 > ${default_port:-$default_port_value} ]]
then
echo $1 > $default_port_file
fi
}
get_default_port
echo "---Using [$default_port] as default port-- : "
read hp1

hp1=${hp1:-$default_port}
echo "Port number used = $hp1"

set_default_port $((hp1+1))
fi

--

echo -n "Enter hp2 port: "
read hp2
if [ -z $hp2 ]
then

default_port_file=.default_port_hp2
default_port_value=443

get_default_port()
{
if [ -f $default_port_file ]
then
default_port=$(<$default_port_file)
else
default_port=$default_port_value
fi
}
set_default_port() {
if [[ $1 > ${default_port:-$default_port_value} ]]
then
echo $1 > $default_port_file
fi
}
get_default_port
echo "---Using [$default_port] as default port-- : "
read https_port

hp2=${hp2:-$default_port}
echo "Port number used = $hp2"

set_default_port $((hp2+1))
fi
