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

QUOTA(8)						      System Manager's Manual							  QUOTA(8)

 *

NAME

       quota - report and optionally fix quota usage

SYNOPSIS

       quota [ -C config-file ] [ -d domain ] [ -f ] [ mailbox-prefix...  ]

DESCRIPTION

       Quota generates a report listing quota roots, giving their limits and usage.  If the -f option is given, quota first fixes any inconsisten-
       cies in the quota subsystem, such as mailboxes with the wrong quota root or quota roots	with  the  wrong  quota  usage	reported.   If	an
       optional  domain is given, the quota listing (and inconsistency fixing) is performed in that domain rather than the default domain.  If any
       optional mailbox-prefix arguments are given, the quota listing (and inconsistency fixing) is limited to quota roots with names  that  start
       with one of the given prefixes.

       Running quota with both the -f option and mailbox-prefix arguments is not recommended.

       Quota reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C.

OPTIONS

       -C config-file
	      Read configuration options from config-file.

       -d domain
	      List/fix quotas in domain.

       -f     Fix any inconsistencies in the quota subsystem before generating a report.

FILES

       /etc/imapd.conf
