Getip is a shellscript that will retrieve your IP address from the command line
#!/bin/bash # get ip /sbin/ifconfig $1 | grep inet | awk '{print $2}' | sed 's/^addr://g'
To do it without any external commands (apart from ifconfig), or to get your Internet address if you are behind a NAT:
## The -n option retrieves the Internet IP address ## if you are behind a NAT if [ "$1" = "-n" ] then ip=$(lynx -dump http://cfaj.freeshell.org/ipaddr.cgi) else if=$1 ## specify which interface, e.g. eth0, fxp0 system=$(uname) case $system in FreeBSD) sep="inet " ;; Linux) sep="addr:" ;; esac temp=$(ifconfig $if) temp=${temp#*"$sep"} ip=${temp%% *} fi printf "%s\n" "$ip" ### CFAJ ###
