Need help with awk

#!/bin/bash

ARCHIVE="$PWD"
#ARCHIVE="/home/kschmidt/public_html/Files/DrMathArchive"

echo `ls "$ARCHIVE"`
ls "$ARCHIVE" | while read DIR
do
#     echo $DIR

#        [ -d "$DIR" ] || continue # Ignore non-directories
#echo "Dir is: "$ARCHIVE"/$DIR"

       for EACHFILE in "$ARCHIVE/$DIR/prob"*
       do
#           echo $EACHFILE
              TEMP3="${EACHFILE##*/}"

              TEMP2="${TEMP3%%_*}"

              # Use globbing to count files.
              set -- "$ARCHIVE/$DIR/${TEMP2}"*
              echo "$TEMP2" "$#"
        done
done > outputfile

sort -u outputfile -o outputfile
sort -k2 -nr outputfile -o outputfile
GREATER=head -1  outputfile | awk '{print $2}'
echo "This is : $(GREATER)"

awk '{if ($2 = 10 ) {print $1}}' outputfile

At the end of my code I am trying to store head -1 outputfile | awk '{print $2}' into GREATER, but everything I do fails. I need to do this because I need that value to compare in the last if so instead of 10 I need ${GREATER}. Any ideas?

Try

 
GREATER=`head -1  outputfile | awk '{print $2}'`

I have tried that, but it does not work, no idea why?

Can you elaborate the issue that you observe?

5

yes it states greater no command found

Your problem is this line:

echo "This is : $(GREATER)"

should be

echo "this is $GREATER"

It's trying to execute GREATER.

You also don't need to use head if you are using awk:

GREATER=$(awk '{print $2; exit(0); }' outputfile )
