How to determine Mac OS X version in shell script?

I need to run make with one parameters set if it is running under Capitan and with other parameters in Sierra. In other words: I run in command line:

sw_version ProductName: Mac OS X ProductVersion: 10.13.6

How I can get the value of ProductVersion to the variable and check it if current OS version <10.13 then else

The below command works on latest versions of macOS:

os_ver=${$(sw_vers -productVersion)}
if [[ $os_ver -gt 10.13 ]]; then
    echo "$os_ver  is above 10.13"
else
    echo "$os_ver is below 10.13"
fi

try the sw_vers command. See examples here : https://www.cyberciti.biz/faq/mac-osx-find-tell-operating-system-version-from-bash-prompt/

to get product version : 

sw_vers | grep ProductVersion | cut -d':' -f2

to compare the parsed value :

base_ver=10.13
ver=$(sw_vers | grep ProductVersion | cut -d':' -f2 | tr -d ' ')
if [ $(echo -e $base_ver"\n"$ver | sort -V | tail -1) == "$base_ver" ]
then 
   echo "older"
else 
   echo "newer"
fi
