Java version comparison if/else
I want to compare the version before installing an application, but i keep on getting this error:

line 4: [: 3.1.0.4880: integer expression expected

version value is obtained from a xml.

Code:
file_version=`awk -F"[<>]" '/CFBundleVersion/ {getline;print $3;exit}' Info.plist`
VALID_VERSION="3.1.0.4880"
if [ "$file_version" -ge "$VALID_VERSION" ];then
        echo "VERSION OK"
else
        echo "INSTALL"
fi
