I need to make a shell script that displays config files without the commented and empty lines

This is my code:

echo "Type in your file"
read file
sed -r -e 's/(^(^#)*$) ; s/(^(^;)*$) ; s/(^(^$)*$) ; s/(^(^/)*$) ; s/(^(^ )*$)' $file

This is the output when I give it a file:

sed: -e expression #1, char 31: unknown option to `s’

Why am I getting this error? Would you suggest another way to do it?
Thanks in advance
