使用脚本将Nic卡的IP地址打印到bash

Question

currently I am working on a school assignment on Linux using Vim where I have to write a script that displays the user that is currently logged in, the time and date, and list only the IP address of the Nic card. I have everything working except for the IP address part. If anyone could help I would appreciate it greatly.

Edit to include the code I have at the moment.

#!/bin/bash
Time=$(date)
IP=$(ifconfig ens33)
echo "The following user is currently logged in $USER"
echo ""
echo "The current time is $Time"
echo ""
echo "The IP information is $IP"

Answer 1

You can filter the result of ifconfig using awk like this (IPv4):

$ ifconfig ens33 | awk '/inet addr/{print substr($2, 6)}'

Result:

10.10.xx.xx

inet addr: represents IPv4 address.
inet6 addr: represents IPv6 address.

IP=$(ifconfig ens33| grep inet | sed 's/ */ /'  | cut -d" " -f3)
