i'm gonna write do:

#configuration version=1.0.0 url='http://example.com/version' dl_url='http://example.com/download' #later on whenever want # assume url displays current version number check_version=$(wget -o- "$url") # if remove periods, works way # lexicorigraphically compare version numbers numbers current_number=$(echo "$version" | tr -d '.') new_number=$(echo "$check_version" | tr -d '.') test "$current_number" -gt "$new_number" || x-www-browser "$dl_url"
