I have an install script that does some stuff with mysql (i.e. install,
start, etc). It installs
mysql Ver 14.12 Distrib 5.0.19, for pc-linux-gnu (i686) using readline 5.0
This was good when we just used CentOS 4.5. Now we are doing some later
CentOS versions and the mysql version may be higher.
I want to do something like "mysql --version" and process the result and
if the version is >= 5.0.19 skip the mysql installation and just do the
other stuff. I can't compare as it is right now because the . and stuff
may screw up the comparison (e.g. ver 5.2 will show as greater than 5.19
I want to know, if I break the individual pieces like 14 12 5 0 19 I can do
some sort of calculation to determine a number that I can actually compare.
Or can I just remove all the decimal points, like 220.127.116.11.19 becomes
14125019? I might have to make it like 14120050019 or something.
What is an algorithm I can use?
