You have several mistakes.
- You have spaces before and after
=
- You compare numbers with
>you should use-gt
- You use brackets
()inif
Use this way:
df -h | awk '{ print $5 , $1 }' > sample.txt
while read -r line;
do
echo $line
var1=$( echo $line | cut -d "%" -f5 )
if [[ "$var1" -gt 90 ]]
then
echo $line sample1.txt
fi
done < sample.txt

Also, concatenating fields with an explicit space inawkis not needed if one uses the defaultOFSvalue. Use of unquoted variable expansions is bad. The output filesample.txtseems unneeded. The whole script could be replaced by a one-liner. No comment on these things?
