Inquiry on Grabbing info from file.
Here is another script I am trying to customize currently,

this script is used to send me disk space information, but at the moment I have to enter all the servers in manually SERVER= "xxx bbb ccc" ect..

how can I script it so that the servers are called off a txt file versus me entering all of them ? my intention is to separate them PROD, QA ect.. and call those txt files and environments when needed.

Like a plug and play.
Code:
#!/bin/bash
Date="'date +%m/%d/%y %H:%M:%S'"

SERVERS="xxx bbb ccc" 
USR="me"

# Email
SUBJECT="Disk Free Verification for Hosts"
EMAIL="xxx@ex"
EMAILMESSAGE="/u/home/xxx/AccountV.txt"

# create new file
>$EMAILMESSAGE

# connect each host and pull up user listing
for host in $SERVERS
do
echo "--------------------------------" >>$EMAILMESSAGE
echo "* HOST: $host " >>$EMAILMESSAGE
echo "--------------------------------" >>$EMAILMESSAGE
ssh $USR@$host df -h | sed '/platform/d' >> $EMAILMESSAGE
done

# send an email using /bin/mail
#/bin/mail -s "$SUBJECT" "$EMAIL" < $EMAILMESSAGE
mailx -s "$SUBJECT" "$EMAIL" < $EMAILMESSAGE

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME

       uudemon.admin,  uudemon.cleanu,	uudemon.hour,  uudemon.poll  -	Administrative shell scripts for polling remote systems, cleaning up spool
       directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons

SYNOPSIS

       These shell scripts reside in the following directory:
	  /usr/lib/uucp

DESCRIPTION

       All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the  scripts,  remove
       the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.

       This  script  reports  status  to  the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
       results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID  (uucpa)	or
       root.  This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
       mand is run with the following parameters: -C7, -D7, X2, -o2, -W1.  This script runs the uusched and uuxqt daemons in the background.  This
       script  polls  the  systems  listed  in	the  /usr/lib/uucp/Poll file.  The uudemon.poll script should be scheduled before the uudemon.hour
       script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.

FILES

       Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files.  Contains the uucp file.

RELATED INFORMATION

       Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)

       Files: /usr/lib/uucp delim off
