Execute command only works as root

[satimis]

Hi all,

I was following

Postfix Virtual MailBox Clam Smtp Howto
https://help.ubuntu.com/community/Po...=recall&rev=82

building an mail server, creating /usr/local/sbin/deldovcotuser to delete users.

However it can only work as root. On running;

$ sudo deldovecotuser user@mydomain.com

read: 18: Illegal option -n

Aborting....

it complains.

$ cat /usr/local/sbin/deldovecotuser

 #!/bin/bash
#
# deldovecotuser - for deleting virtual dovecot users
#
if [ ! $# = 1 ]
 then
  echo -e "Usage: $0 username@domain"
  exit 1
 else
  user=`echo "$1" | cut -f1 -d "@"`
  domain=`echo "$1" | cut -s -f2 -d "@"`
  if [ -x $domain ]
   then
    echo -e "No domain given\nUsage: $0 username@domain: "
    exit 2
  fi
fi
read -n 1 -p "Delete user $user@$domain from dovecot? [Y/N]? "
echo
case $REPLY in
 y | Y)
  new_users=`grep -v $user@$domain /etc/dovecot/users`
  new_passwd=`grep -v $user@$domain /etc/dovecot/passwd`
  new_vmaps=`grep -v $user@$domain /etc/postfix/vmaps`
  echo "Deleting $user@$domain from /etc/dovecot/users"
  echo "$new_users" > /etc/dovecot/users
  echo "Deleting $user@$domain from /etc/dovecot/passwd"
  echo "$new_passwd" > /etc/dovecot/passwd
  echo "Deleting $user@$domain from /etc/postfix/vmaps"
  echo "$new_vmaps" > /etc/postfix/vmaps
  postmap /etc/postfix/vmaps
  postfix reload
  read -n1 -p "Delete all files in /home/vmail/$domain/$user? [Y/N]? " DELETE
  echo
  case $DELETE in
   y | Y)
    echo "Deleting files in /home/vmail/$domain/$user"
    rm -fr /home/vmail/$domain/$user
   ;;
   * )
    echo "Not deleting files in /home/vmail/$domain/$user"
   ;;
  esac
 ;;
 * )
  echo "Aborting..."
 ;;
esac

adddovecotuser works on sudo.


$ ls -ld /usr/local/sbin/deldovecotuser

 
-rwxr-xr-x 1 root staff 1256 Mar  5 17:13 /usr/local/sbin/deldovecotuser

$ ls -ld /usr/local/sbin/adddovecotuser

-rwxr-xr-x 1 root staff 1678 Mar  5 16:52 /usr/local/sbin/adddovecotuser

Google didn't find me a solution. Please help. TIA
