Global Zone getting crontab info from zone

Hi,

First post.

I have a script that I am having a little trouble with and I hope someone can help.

I will post the code for your input, but I want to read the lines of a file and use this as input to a command in a while loop...

Code:

#!/bin/sh
#
#
###  Variables
MSG=/tmp/tmptest.txt
HOST=`hostname`
DAT=`date`
ZONES=/tmp/tmpzones.txt

#this next line works fine
zoneadm list | grep -v "global" | sort >> $ZONES

# the next line performed here works perfectly well - if I type the server name in manually  (hashed out just now)
# zlogin SERVER_NAME crontab -l | grep "/shutdown" >> $MSG

while read ZONE
do
  # the next line is what i want to achieve, but does not work - tried different combinations of " ' ` in different places...
  #echo zlogin "$ZONE" crontab -l | grep "/shutdown" >> $MSG
  # the next line proves the while loop works
  echo "this works for $ZONE" >> $MSG
done <"$ZONES"

Say my ZONES file produces
Server1
Server2
Server3

then my while loop just now produces:
"this works for Server1"
"this works for Server2" ... etc

but I am wanting to do a zlogin to the server(s) within the global zone to get the crontab info of that server if it has a reboot set.. then i can email it out to the relevant users.

can anyone help?

crontab

CRONTAB(1)						      General Commands Manual							CRONTAB(1)

NAME

       crontab - maintain crontab files for individual users (ISC Cron V4.1)

SYNOPSIS

       crontab [-u user] file
       crontab [-u user] [-l | -r | -e]

DESCRIPTION

       Crontab	is  the  program  used	to install, deinstall or list the tables used to drive the cron(8) daemon in ISC Cron.	Each user can have
       their own crontab, and though these are files in /var, they are not intended to be edited directly.

       If the cron.allow file exists, then you must be listed therein in order to be allowed to use this command.  If the cron.allow file does not
       exist  but  the	cron.deny  file does exist, then you must not be listed in the cron.deny file in order to use this command.  If neither of
       these files exists, only the super user will be allowed to use this command.

       If the -u option is given, it specifies the name of the user whose crontab is to be tweaked.  If this option is not given, crontab examines
       "your"  crontab,  i.e.,	the  crontab of the person executing the command.  Note that su(8) can confuse crontab and that if you are running
       inside of su(8) you should always use the -u option for safety's sake.

       The first form of this command is used to install a new crontab from some named file or standard input  if  the	pseudo-filename  ``-''	is
       given.

       The -l option causes the current crontab to be displayed on standard output.

       The -r option causes the current crontab to be removed.

       The -e option is used to edit the current crontab using the editor specified by the VISUAL or EDITOR environment variables.  After you exit
       from the editor, the modified crontab will be installed automatically.

       crontab(5), cron(8)

FILES

       /etc/cron.allow
       /etc/cron.deny

STANDARDS

       The crontab command conforms to IEEE Std1003.2-1992 (``POSIX'').  This new command syntax differs from previous versions of Vixie Cron,	as
       well as from the classic SVR3 syntax.

DIAGNOSTICS

       A fairly informative usage message appears if you run it with a bad command line.
