[shell] compare Qt version

[bibax]

Hi,

I have a script which permit to install Qt 3.3.4
But before installing, I want to verify if the user has a newer version else, I install mine.

How can I do this?

I find the Qt directory (/usr/local/lib/Qt*.*.* or /usr/lib/Qt*.*.*) and I want to compare the end (ex : 3.3.3) with my number version (3.3.4).
I know how take directory name (basename /usr/local/lib/Qt*) but I have a problem to compare with Qt3.3.4.
I don't know how compare these.

If u have any idea !!

Have a nice day

You can use the cut command with the -d option to get either
the whole extension or a specific field of the extension.

somehow get the name of the qt directory into the variable 'dir' and then:

version=`echo ${dir#*[a-zA-Z]}`
