UNIX for Dummies Questions & Answers

Still a Beginner here ..

Does anyone no how to get the IP address of the machine thats logged in (bearing in mind there will be others logged in) while they are logged in to the Unix server and pass this as a variable to a shell script so as I can FTP files to that machine via a shell script, at present I have only developed the ftp/shell script to a specific (named) machine

I would like "HOST" to equal the persons ipaddress that is logged in if possible

sample of present code

#! /usr/bin/ksh

HOST=gerry
USER=gerry
PASSWD=letmein
DIR=/uploads
exec 4>&1
ftp -nv >&4 2>&4 |&
print -p open $HOST
print -p user $USER $PASSWD
print -p cd c:\
print -p dir c:\uploads
print -p binary
print -p get $DIR/CHEST /u1/excel/Kenny/CHEST
print -p bye
wait
exit 0
bye

you can use "who -q <user>" to get the IP-address (i tried that on AIX 5.2) and put that info into your variable.

Sample output of "who -q":
f985905 (130.20.158.93)

Therefore:

HOST="$( who -q | sed 's/.*(\([^)]\).*/\1/' )"

thanks for that but under Data General -Unix that command does not work but, the only command that'll produce an IP address that i'm aware of is finger and last
