Compare file sizes in shell script

Question

I'm trying to compare the size of two files in shell script but I'm getting a test: 32: 8: unexpected operator error.

I=`wc -c $i | cut -d' ' -f1`
J=`wc -c $j | cut -d' ' -f1`
if test $I == $J
then
      echo $i $j >> $1.pares
fi

I test the values in $I and $J using echo and the values are correct but I cant compare them...

Answer 1

this works on bash

if((`stat -c%s "$file1"`==`stat -c%s "$file2"`));then
  echo "do something"
fi
