Hi i have used this code snippet to input a file and count the number of tabs in each line and print the result to output file, but i m getting the error

awk: cmd. line:1: Unexpected token

What could be the mistake

#!/bin/sh
FILE='unit-1-slide.txt'
OUTPUTFILE='output-for'-$FILE
COUNT=$(awk '{print gsub(/\t/,"")}'$FILE)
OUTPUT_PATH='/home/user/Desktop'
echo $COUNT > $OUTPUTFILE
echo "Done!"
                By convention all-upper-case variable names are reserved for exported variables. Also, always quote your variables (e.g. "$FILE" instead of $FILE) to avoid undesirable consequences of filename expansion, etc. Finally, the awk command could be written more clearly as awk -F'\t' '{print NF}'.
