Display current IP address

ust3 — Tue, 24 Jul 2007 06:05:37 GMT

I would like to have a shell script that can display the user IP address , I think it is similiar to "who -m | awk -F: '{ print $6}'" , this script is used to display what IP is when the user run the program . thx in advance.

Hi,

this may lead to a multiple line output, if more than one interface is configured:
netstat -in | awk 'NR>1 && !/lo/ {print $4}'

To get the first entry only:
netstat -in | awk 'NR>1 && !/lo/ {print $4; exit}'

Hello,

You could add the following to /etc/profile or the user's .profile:

export REMOTE_HOST=$(who -mu | awk '{print $8}')
export REMOTE_IP=$(/usr/sbin/arp ${REMOTE_HOST} | awk '{gsub(/[()]/,"",$2)}END{print $2}')

Then just echo ${REMOTE_IP}.

In general, it is best to use awk's $NF variable to get the last field. Counting fields (ie, $5 $6, etc) means that a change the format of preceeding data will shift the last field. Something like this:

who -muR | awk '{print $NF}'
or
MYIP=$(who -muR | awk '{print $NF}')

Hi ust3, you can try this:

who -u | grep ernesto | awk '{print $8}' | sort | uniq

where "ernesto" is the login_name.

Best regards.
