Assign output of file run or string of commands to shell varriable...

[chadrt]

Here is what I have so far...

#!/bin/bash

### DELETED THE CONTENTS OF THESE VARIABLES FOR POSTING PURPOSES
TO="" # WHO IS TO RECEIVE THE EMAIL
FROM="" # WHO IS THE EMAIL FROM USUALLY SAME AS THE USER
SERV="" # THE SERVER TO USE AND THE PORT server:port IS THE FORMAT
USER="" # USERNAME OF THE OUTBOUND SERVER
PASS="" # PASSWORD OF THE OUTBOUND SERVER
SUB="bla bla bla"

###### So I have tried both of these ######
MSG= 'echo $(expr '(' $(date -d 2015/08/17 +%s) - $(date +%s) + 86399 ')' / 86400) " Days Until Close"'
#MSG= /path/to/daysuntil.sh # This contains the line from above runnnig this alone works fine!

/usr/bin/sendEmail -f $FROM -t $TO -u $SUB -m $MSG -s $SERV -xu $USER -xp $PASS

Here is another line I have been experimenting with...

echo $(($(date -d 17-Aug +%j) - $(date +%j))) Days Until Close
