Try to echo the variable $forproblemmail before the line with the error or run the script in debug mode.
Add the this line below the shebang:
Code:
set -x

Here is what I got, after i added "set -x" :

Code:
-bash-3.2$ ./diff_check.sh
++ diff -r /loc1/dir1 /loc2/dir2
++ wc -l
+ DIFF=0
+ '[' 0 -ne 0 ']'
+ echo 'No Difference'
No Difference
++ diff -r /loc1/dir1 /loc2/dir2
++ grep Only
+ DIFF2=
+ '[' 1 -eq 0 ']'
+ echo 'No files to display, as diff check is good'
No files to display, as diff check is good
+ '[' -eq 1 ']'
./diff_check.sh: line 25: [: -eq: unary operator expected
+ SUBJECT='GOOD: Diff Success'
+ EMAIL=admin@somewhere.com
+ EMAILMESSAGE=/tmp/diffmessage.txt
+ mail -s 'GOOD: Diff Success' admin@somewhere.com
Null message body; hope that's ok

Assign a value to the variable forproblemmail in the else part:
Code:
if [ $? -eq 0 ]
then
  echo "The names of the different files and their paths are:
  ${DIFF2}."
  forproblemmail=1
else 
  echo "No files are different"
  if [ -z $forproblemmail ]; then
    forproblemmail=0
  fi
fi
