alphanumeric comparision

I have a requirement where I need to check if

r1v07l08ab < r1v07l09ak

r1v07l09ab < r1v07l09ac

r1v07l09ab < r1v07l09if
where r1v07l09ab is a software release.

I should always check for this to be true to continue the release deployment because an older release should not be deployed by mistake. I mean only the release greater than the current release should be deployed on the server.

please help.

Thanks in advance.

    if ("r1v07l09ab" < "r1v07l09ac" ) print "yup"
    else print "nope"

Tools Pass Shell variables and return the response back to shell

this way I can pass SHELL Variables $prevRelease and $curRelease and also return the result back to SHELL

VALID=`echo "$prevRelease $currRelease" | awk '{ if($1 < $2) print "1"; else print "0" }'`

Thanks ghostdog74 and porter for your responsesSmilie
