comparing two tables

I am comparing two table structure in different databases,Put into 2 txt files , when comparing if column sequnce and data type is not matching ,it has to display that info else Table structure is ok.

wrote shell script ,its not working .I am getting "Table structure is not ok" even if both are in similar.

tab1=$1
tab2=$2

if [ ! -f $tab1 ] ; then
echo "file1 not exist:$tab1"
fi
if [ ! -f $tab2 ] ; then
echo "file2 not exist:$tab2"
fi
col1=`awk -F" " '/SET TABLE/{print substr($4,(index($4,".")+1))}1' $tab1 |egrep -iv 'create|journal|default|index'| sed -e
's/(//g' -e 's/)//g'|awk -F " " '{print $1 }'`

len1=`awk -F" " '/SET TABLE/{print $4}1' $tab1 |egrep -iv 'create|journal|default|index'|awk -F " " '{print $2 }'`

col2=`awk -F" " '/SET TABLE/{print substr($4,(index($4,".")+1))}1' $tab2 |egrep -iv 'create|journal|default|index'| awk -F
" " '{print $1 }'`

len2=`awk -F" " '/SET TABLE/{print $4}1' $tab2 |egrep -iv 'create|journal|default|index'| sed -e 's/(//g' -e 's/)//g'|awk -
F " " '{print $2 }'`

if [ "$col1"=="$col2" && "$len1"=="$len2" ]; then

echo "Table structure is ok"

else
echo "Table structure is not ok"
echo "$col1 $len1\n"
echo "$col2 $len2\n"
fi
=============

Getting the below error message when calling the following script

ab.sh Tab1.txt Tab2.txt

ab.sh[18]: test: ] missing
