inetipinfo – is a script, that will find/return your internet ip address on a linux machine


After searching for a program or a script for my linux distribution, that will give me my Internet ip address, i didn’t find

any. So I decided to write my own script, that has been tested and works. You can either copy the code from here, or a better

way is to download the package from the link below, and install it.


#!/bin/bash

function message {
echo “Usage: `basename $0` [-n]”
echo “Outputs your internet IP address.”
echo “”
echo “Options:”
echo ” -n, –no-text : returns only the IP address without text”
echo ” -h, –help : show this usage message”

echo “Mail bug reports and suggestions to Robert Mileski .”
}

function get_ip {
my_ip=`wget -q -O – http://www.myipaddress.com | grep -E ‘(^|[\>])[0-9]*\.[0-9]*\.[0-9]*\.[0-9]*([\<]|$)’ | sed

-e ‘s/<p>//’ -e ‘s/<b>//’ -e ‘s/<\/b>//’`
}

function exec_get_ip {
get_ip
if [ -z $my_ip ]; then
exit 1
else
echo $my_ip
fi
}

NO_ARGS=0
E_OPTERROR=65
wget_check=`which wget`

if [ $# -gt 1 ]; then
message
exit $E_OPTERROR
fi

if [ -z $wget_check ]; then
echo “You must have the wget package to use this script. Please first install wget.”
exit 1
fi

if [ $# -eq “$NO_ARGS” ]; then
get_ip
if [ -z $my_ip ]; then
echo “No connection to the Internet”
exit 1
else
echo “Your Internet IP address is: $my_ip”
exit 0
fi
fi

while getopts “nh-:” Option
do
case $Option in
h) message;;
n) exec_get_ip;;
-) case $OPTARG in
help) message;;
no-text) exec_get_ip;;
*) message;;
esac;;
*) message
exit $E_OPTERROR;;
esac
done

Don’t forget to make the file executable with chmod +x name

You can also download the whole installable script from this link: http://www.cscsoft.com/inetipinfo.tar.gz
Just extract the file, and run sudo make install

Best regards,
