Shell Scrips

Sometimes it is easier to write a short shell script that reads the PBX database and prints it on the screen, or does other functions with it. This page shows some examples of useful functions.

MAC Overview​

The first shell script shows how to list the MAC addresses that have been assigned to extensions.

#!/bin/bash 
function get_xml()
{
 gawk -v tag=$1 'BEGIN{regex="<" tag ">([^<]*)</" tag ">";}{ match($0, regex, m); for(i = 1;; i++) { if(!(i in m)) break; printf("%s\n",m[i]);}}' $2
}

for mac in macs/*.xml
do
  name=${user:5} 
  # only the name
  user=$(get_xml user $mac)    
  adr=$(get_xml adr $mac)
  alias=$(get_xml alias users/$user.xml)
  domain=$(get_xml domain users/$user.xml)
  echo $adr $(get_xml name user_alias/$alias.xml)@$(get_xml name domains/$domain.xml)
done

Count Extensions​

This script count how many extensions are in each domain.

#!/bin/bash
# Show the passwords of all users:
function get_xml()
{
 gawk -v tag=$1 'BEGIN{regex="<" tag ">([^<]*)</" tag ">";}{ match($0, regex, m); for(i = 1;; i++) { if(!(i in m)) break; printf("%s\n",m[i]);}}' $2
}

for dom in domains/*.xml; do
  name=${dom:8}
  # only the name
  idx=${name%.xml}
  # only the number  
  dn=$(get_xml name $dom)  
  if [ ! -z "$dn" ]; then
    count=0
    for ext in users/*.xml; do          
      domain=$(get_xml domain $ext)          
      if [ "$domain" == "$idx" ]; then          
        type=$(get_xml type $ext)             
        if [ $type == "extensions" ]; then
          count=$[$count+1]              
        fi
      fi
    done
  echo $dn $count
  fi
done

Show Email Addresses​

This script shows the various email addresses .

#!/bin/bash
# Show the emails of the users
function get_xml()
{
 gawk -v tag=$1 'BEGIN{regex="<" tag ">([^<]*)</" tag ">";}{ match($0, regex, m); for(i = 1;; i++) { if(!(i in m)) break; printf("%s\n",m[i]);}}' $2
}

for xml in users/*.xml; do
  n=$(get_xml alias $xml) 
  name=$(get_xml name user_alias/$n.xml)  
  d=$(get_xml domain $xml)
  domain=$(get_xml name domains/$d.xml)  
  email=$(get_xml email_cdr $xml)  
  [ -n "$email" ] && echo $name@$domain: $email
  type=$(get_xml type $xml)
  if [ $type = extensions ]; then
    id=$(get_xml id $xml)
    for t in email_address email_recadr wakeup_fail_email; do
      email=$(get_xml $t extensions/$id.xml)
      [ -n "$email" ] && echo $name@$domain: $email
    done
  fi
done
for xml in domains/*.xml; do
  domain=$(get_xml name $xml)
  for t in email_cdr e911_emails billing_email; do
    email=$(get_xml $t $xml) 
    [ -n "$email" ] && echo $domain: $email
  done
done
