[Exim] exim admin script - eximadm

Hello,
for those who are interested I have a simple dialog-based admin tool that allows
to view the exim queue, thaw/freeze/delete and cancel waiting messages. The bash
script should be self-explanatory, so here it is:


#!/bin/bash
# eximadm is written by B. Hochstrasser (bhoc@???)
# this is GPL
#
# this is a simple dialog-based exim mail queue admin tool.
# if you don't know exim, go to http://www.exim.org
#

# some constants
# where is exim?
EXIMCMD="/usr/bin/exim"
# this matches frozen msgs
FROZEN="*** frozen ***"
# get a filename for the temp file
TMPFILE="/tmp/eximadm-$(date +%s)"
# filter out all but '-00 <'
MATCH="\-[0-9][0-9] <"
# sed script
SEDCMD="s/>.*$/> 0/"

# some functions
thaw ()
{
MSGLIST=$(${EXIMCMD} -bp | grep "${MATCH}" | grep "${FROZEN}" | cut -b 11- | sed -e "${SEDCMD}" | tr "\n" " ")
if [ -n "${MSGLIST}" ]; then
  dialog --title "Thaw Messages" --checklist "Message ID - Sender" 0 0 0 ${MSGLIST} 2>${TMPFILE}
  MSGLIST=$(cat ${TMPFILE} | tr -d '"')
  if [ -n "${MSGLIST}" ]; then
    EXIMSG=$(${EXIMCMD} -Mt ${MSGLIST})
    RM ${TMPFILE} 
    if [ -n "${EXIMSG}" ]; then
      dialog --title "Exim Messages" --msgbox "${EXIMSG}" 0 0
    fi
  fi
fi
}

freeze ()
{
MSGLIST=$(${EXIMCMD} -bp | grep "${MATCH}" | grep -v "${FROZEN}" | cut -b 11- | sed -e "${SEDCMD}" | tr "\n" " ")
if [ -n "${MSGLIST}" ]; then
  dialog --title "Freeze Messages" --checklist "Message ID - Sender" 0 0 0 ${MSGLIST} 2>${TMPFILE}
  MSGLIST=$(cat ${TMPFILE} | tr -d '"')
  if [ -n "${MSGLIST}" ]; then
    EXIMSG=$(${EXIMCMD} -Mf ${MSGLIST})
    RM ${TMPFILE} 
    if [ -n "${EXIMSG}" ]; then
      dialog --title "Exim Messages" --msgbox "${EXIMSG}" 0 0
    fi

}

editall ()
{
MSGTITLE=$1
EXIMOPT=$2
if [ -n "${EXIMOPT}" ]; then

viewqueue ()

}

# the main loop

until [ -z "${CMD}" ]; do

    case "${CMD}" in
      view) viewqueue;;

Have fun! Ben
