[Lazarus] Determining OS

[Chris Kelling]

Thank you for the suggestions so far - 

 

$ lsb_release seems to give good information, my Fedora 15 machine returns

LSB Version:     :core-4.0-ia32:core-4,0-noarch

 

In addition, I did a ls of the /etc directory and found a file called
system-release-cpe,  Looking in it says cpe:/o:fedoraproject:fedora:15

Now, this may be unique to fedora (isn't open source wonderful?), but if all
distros have that file, I think that may be the solution,  I've got an
ubuntu machine running, too - I should look to see what it has.

 

Say what you will about the windows registry, but at least there's a common
place to look for and put information.  And no, I don't want to start a war
over the merits of one OS over another, just trying to make my program
portable to the most machines with the least effort for the end user.

Any distro worth using should support the LSB standards. With that
being said, you can use the 'lsb_release' command to find out exactly
what distribution and version is being used.


I'm using Arch Linux and that is my output:

------------------------
$ lsb_release 
LSB Version:    n/a

$ 
-------------------------

But I have the following file:
/etc/arch-release


I think that looking for /etc/*release is more reliable at the moment for
distros. 

BTW The TRegistry class is cross platform. On Windows it uses Registry, and
on other OS, it uses INI files.
