Re: [Modules] How to detect the current Linux distribution?

[Frank T. <f.t...@dk...>]

That seems good idea, as I manage the central profile files in 
/etc/profile.d where I could set "export DISTRO=..." and then have 
somthing like the following in the modulefiles:

switch $env(DISTRO) {
     "openSuse" {
         set basepath /a/b/c
     }
     "CentOS" {
         set basepath /x/y/z
     }
}

(I got that from some Tcl tutorial page ;-)

and then continue with the distro specific $basepath.

I'll try that tomorrow.

Cheers 7 thanks
frank
