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

[Sternberg, M. G. <ste...@an...>]

Frank,

Distro-detection and distro-specific code inside individual modulefiles would be repetitive and fragile, and would quickly become difficult to maintain. For a multi-distro system here, I use several modulefile trees, presenting distro-specific trees before shared ones:

	$ echo $MODULEPATH 
	/opt/apps/M/el6:/opt/apps/M/el:/usr/share/Modules/modulefiles:/etc/modulefiles


To add to what Paul just wrote, lsb_release(1) is provided on CentOS by package redhat-lsb-core. As part of scripts in /etc/profile.d/, I use:

	$ lsb_release -sir
	CentOS 6.9

Has a nice ring to it and is easy to parse.


With best regards,
Michael
