ここには、自明なはずの小さなスクリプトがありますが、なぜwhileループが関数を正しく処理しないのかわかりません。ユーザーがnoを押してNを押した場合は、再びgetinfo関数を表示し、ユーザーがyesを押した場合はwriteinterfacefile関数を実行する必要があります。
#!/bin/bash

スクリプトでいくつかの間違いを見つけました。私はそれがどうあるべきかを考えます(これらがこのスクリプトをやりたいことだと仮定して):
#!/bin/bash
getinfo()
{
read -p "Enter the IP of your router: (looks like 192.168.1.1) " routerip
read -p "Enter the netmask for your network: (looks like 255.255.255.0) " netmask
read -p "Enter the ip address for your server: (looks like 192.168.1.22) " staticip
}
writeinterfacefile()
{
cat << EOF > $1
