Answer

 * 1) !/bin/bash

IPS="192.168.23.5 47.45.56.11 189.67.24.21" count=1
 * 1) IPS=$(ifconfig | awk '/inet/ { print $2 }' | awk -F ":" '{ print $2 }')

for IP in $IPS; do IP[$count]=$IP; echo "Found IP $count - ${IP[count]}"; count=`echo $count+1 | bc` done

read -p "Which IP do you want to use? (number)" choice

IPCHOICE=${IP[$choice]} echo "Your choice was $choice - Setting IP to $IPCHOICE "


 * 1) ifconfig ...

Schwanzersatzfaktor-Berechnung
Das folgende Shell-Script (by unbekannt) errechnet den Schwanzersatz-Faktor eines Linux-Rechners:

LC_ALL=C echo `uptime|grep days|sed 's/.*up \([0-9]*\) day.*/\1\/10+/'; \ cat /proc/cpuinfo|grep MHz|awk '{print $4"/30 +";}'; free|grep '^Mem' \ {print s/1024/50"/15+70";}'`|bc|sed 's/\(.$\)/.\1cm/'
 * 1) !/bin/sh
 * awk '{print $3"/1024/3+"}'; df -P -k -x nfs | grep -v 1k \
 * awk '{if ($1 ~ "/dev/(scsi|sd)"){ s+= $2} s+= $2;} END \
