grep returns many values into a variable error
I get an error when I grep my results into a variable when the grep finds more than one file.
Code:
FND="$(find ediout* -mmin -60)"
    if [ $FND > '' ]; then
         STR="$(find ediout* -mmin -60 -exec grep -l   "ERRORS Encountered" {} +)"
    fi

When there is only one ediout file it works fine. How do I get around this?

You probably meant this:
Code:
FND="$(find ediout* -mmin -60)"
if [ -n "$FND" ]; then
     STR="$(find ediout* -mmin -60 -exec grep -l   "ERRORS Encountered" {} +)" 
fi

Beware the > sign is not used for comparison but for file redirection, you tried to write to the '' file ...

Not sure if the syntax of your STR=... line is correct, but if it works I wouldn't change it without knowing exactly your need

The error may come from your actual code and not the code you included.
Please post the complete code (specifically around line 43)

The error line 43 =
Code:
"echo "${STR}" | mailx -s "EDI Translation Errors List" test@optonline.net"

The full code =
Code:
    FND="$(find ediout* -mmin -60)"
    if [ $FND > '' ]; then
         STR="$(find ediout* -mmin -60 -exec grep -l "ERRORS Encountered" {} +)"
    fi
#   email the results
    if [ $STR > '' ];  then
        echo "${STR}" | mailx -s "EDI Translation Errors List"  test@optonline.net        The following file(s): ${STR} may contain errors during translation.
MAILER
    fi

Could be better using a workfile for the results not an environment variable.

Code:
find ediout* -mmin -60 -exec grep -l "ERRORS Encountered" {} + > /tmp/results
if [ -s /tmp/results ]
then
      cat /tmp/results | mailx -s "EDI Translation Errors List" test@optonline.net
fi
rm /tmp/results
