Getting IP address by using shell script

« Back to Shell Articles

As we known, being a staff of IT maintanance team, I used to get the IP address from the network configuration, I use this shell script to get the IP address:
[root@yoyojacky ~]# cat getip.sh
#!/bin/bash
# This script is for getting IP address from your local network configuration.

PATH=$PATH:/root/yoyojacky/bin
export PATH

ifconfig eth0 | grep "inet addr" | cut -d: -f2 | cut -d' ' -f1

[root@yoyojacky ~]#


# and also you can use this script: ifconfig eth0 | grep "inet addr" | awk -F: '{ print $2}' | awk -F' ' '{print $1 }'
