Please, review script.

Hi guys,

I 've been brewing this shellscript, but I can't test it until next tuesday.
In the meantime I am too curious wether it will work or not, so I'd like to hear your comments.

Background:
I want to watch the user quota for mailboxes in various email-domains on a IMAP-server.
I have a list of directories in which the user mailboxes reside (domains.txt). The dirnames are named after the specific email-domain.
The users' mailbox quota is at 100 MB.
So if the quota will reach 100MB or more, it is written to a report for the mailserver admin.
And an email is written to the responsable person for the email-domain.

shell=bash
OS=Debian Linux

Thanks & regards, A.

#!/bin/bash
echo " Exceeded mailbox-quota in domains" > /home/tmp/report.txt
echo "*************************************" >> /home/tmp/report.txt
#
ls /home/mailboxes > /home/tmp/domains.txt
#
while read domain; do
cd /home/mailboxes/$domain
echo "Checked mailboxes of $domain...." >> /home/tmp/report.txt
du -k --max-depth=1 | sort -rn > /tmp/$domain.f1
sed -e '1d' < /tmp/$domain.f1 > /tmp/$domain.f2
sed -e 's%./% %g' < /tmp/$domain.f2 > /tmp/$domain.userquota

while read num user; do
if [ $num -ge 100000 ] ; then
echo " $user's mailbox is $num Kb in $domain. This should be 100000" >> /home/tmp/$domain.report.txt
echo " $user's mailbox is $num Kb" >> /home/tmp/report.txt

avahi.service

avahi.service(5)						File Formats Manual						  avahi.service(5)

NAME

       avahi.service - avahi-daemon static service file

SYNOPSIS

       /home/lennart/tmp/avahi/etc/avahi/services/*.service

DESCRIPTION

       /home/lennart/tmp/avahi/etc/avahi/services/*.service  are  XML fragments containing static DNS-SD service data. Every service file can con-
       tain multiple service definitions which share the same name. This is useful for publishing service data for services which implement multi-
       ple protocols. (i.e. a printer implementing _ipp._tcp and _printer._tcp)

XML TAGS

       <service-group> The document tag of avahi service files. Should contain one <name> and one or more <service> elements.

       <name replace-wildcards="yes|no"> The service name. If replace-wildcards is "yes", any occurence of the string "%h" will be replaced by the
       local host name. This can be used for service names like "Remote Terminal on %h". If replace-wildcards is not specified, defaults to "no".

       <service protocol="ipv4|ipv6|any"> Contains the service information for exactly one service type. Should contain one <type> and one  <port>
       element. Optionally it may contain one <domain-name>, one <host-name>, any number of <subtype> and any number of <txt-record> elements. The
       attribute protocol specifies the protocol to advertise the service on. If any is used (which is the default), the service  will	be  adver-
       tised on both IPv4 and IPv6.

       <type> Contains the DNS-SD service type for this service. e.g. "_http._tcp".

       <subtype> Contains an additional DNS-SD service subtype for this service. e.g. "_anon._sub._ftp._tcp".

       <domain-name>  The  domain  name this service should be registered. If omited defaults to the default domain of the avahi daemon. (probably
       .local)

       <host-name> The host name of the host that provides this service. This should be a host that is resolvable by  multicast  or  unicast  DNS.
       Please  note  that  you	need  to  specify a fully-qualified domain name (FQDN) here, i.e. .local is not appended implicitly! The host name
       doesn't need to be part of the domain specified in <domain-name>. See avahi.hosts(5) for more information how to  publish  additional  host
       name mappings.

       <port> The IP port number the service listens on.

       <txt-record> DNS-SD TXT record data.
