Script pour ajouter une adresse IP statique aux interfaces réseau

J'ai un petit script ici qui devrait être assez explicite, mais je ne peux pas comprendre pourquoi la boucle while ne gère pas les fonctions correctement. La fonction getinfo doit apparaître à nouveau si l'utilisateur appuie sur N pour non et si l'utilisateur appuie sur oui, il doit exécuter la fonction writeinterfacefile.

Quel est le problème avec ma boucle?

#!/bin/bash
echo "Let's set up a static ip address for your site"
echo""

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  " netmask
read -p "Enter the ip address for your server:  (looks like 192.168.1.22 " staticip
}

writeinterfacefile()
{ 
cat << EOF >> /home/ubuntu/test 
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet dhcp

#Your static network configuration  
iface eth0 inet static
address echo $staticip
netmask echo $netmask
gateway echo $routerip 
EOF 

}

clear
getinfo
echo""
echo"So your settings are"
echo "Address of your Router is    " echo -n $routerip
echo "The Mask fpr the Network is  " echo -n $netmask
echo "Your decided Server IP is    " echo -n $istaticp
echo""
echo "Are these informations correct? (Y/n)"

while true; do
 read -p "Are these informations correct? [y/N]" yn? 
 case $yn in
   [Yy]* ) writeinterfacefile ;;
   [Nn]* ) getinfo ;;
       * ) echo "Pleas enter Y or n";;
 esac
done

J'ai trouvé des erreurs dans votre script. Voici comment je pense que cela devrait être (en supposant que ce sont les choses que vous voulez faire ce script):

#!/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 
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet dhcp

#Your static network configuration  
iface eth0 inet static
address $staticip
netmask $netmask
gateway $routerip 
EOF
#don't use any space before of after 'EOF' in the previous line

  echo ""
  echo "Your informatons was saved in '$1' file."
  echo ""
  exit 0
}

file="/home/radu/test"
if [ ! -f $file ]; then
  echo ""
  echo "The file '$file' doesn't exist!"
  echo ""
  exit 1
fi

clear
echo "Let's set up a static ip address for your site"
echo ""

getinfo
echo ""
echo "So your settings are:"
echo "Address of your Router is:   $routerip"
echo "The Mask for the Network is: $netmask"
echo "Your decided Server IP is:   $staticip"
echo ""

while true; do
  read -p "Are these informations correct? [y/n]: " yn 
  case $yn in
    [Yy]* ) writeinterfacefile $file;;
    [Nn]* ) getinfo;;
        * ) echo "Pleas enter y or n!";;
  esac
done
