These parts are not terribly linux specific, and deal with desktop systems

It's particularly disappointing in the case of the xdg* utilities, which

Very true, and I see Linux fragmentation become more and more of a
problem. Many people would like to move off Windows for all kinds of
reasons, it's just that the thousands of Linux distros just don't seem
to want that business. Go figure!

Luckily we are in a franchising business, so we can control out
deployment OS with some control. We motivate our franchisees to use
Ubuntu if they decide to go the Linux route. At least that way our

Of course, due to Linux' fragmentation, the standards are most needed on

Yes, but for cases where lsb_release might not work- e.g. an older

I can't believe that distros in today's time still make it so hard for
ISV's to write common (as in distro) desktop applications. Clearly Linux

I did say "a distro worth using". ;-) Just kidding.

But thanks to all that replied regarding the lsb command. Clearly thevarious Linux
distros still need to work on "standardization".

Noting your earlier comments on both lsb_release and xdg-open, the first
thing I'd say is that it strikes me that xdg-open is specifically a
desktop-related program, i.e. it might not be installed on "headless"
systems. Taking that into account, I thought it worth taking a closer
look at a number of systems.

Slackware x86 8.1 with desktop: neither lsb_release nor xdg-open.

Slackware x86 13.37 with desktop: no lsb_release, does have xdg-open.

Debian armel Lenny headless: neither lsb_release nor xdg-open.

Debian armel Lenny with desktop: neither lsb_release nor xdg-open.

Debian armel Squeeze with desktop: has lsb_release, no xdg-open.

Debian mipsel Squeeze with desktop: has lsb_release, no xdg-open.

Debian zSeries Lenny with desktop: neither lsb_release nor xdg-open.

Debian x86 Lenny with desktop: neither lsb_release nor xdg-open.

Debian x86 Squeeze with desktop: both lsb_release and xdg-open.

Debian SPARC Etch with desktop: both lsb_release and xdg-open.

Debian SPARC Lenny with desktop: both lsb_release and xdg-open.

Solaris (8 and 10) have neither lsb_release nor xdg-open as standard.
Same probably applies to BSD.

I find this particularly disappointing since I've used and recommended
xdg-open in the past, on the assumption that since it had appeared in
some distreax and versions it would fairly rapidly be adopted by all.
Mea culpa.

Debian can be recognised by the presence of /etc/apt/sources.list, and
any version that's likely to be encountered will have the release name
in the URLs it contains (older ones referenced 'stable' etc.).

Can somebody confirm this for Ubuntu? Are there comparable files for
other distreax?

An older servo distro we've got around here has neither lsb_release nor 
the xdg utilities, I've not checked either of the Solaris systems. 
Looking at machines in my workroom, all of the Debians currently running 
have both, except for one Lenny which doesn't have lsb_release- other 
Lennies have it.


So while the utilities are undoubtedly useful and underused, it's 
clearly important to have some sort of fallback if they turn out not to 
be available.

Specify some of the other parameters in the 'lsb_release' command and
you will get the exact information your are looking for, on any distro
that supports LSB standard.

Well yes, it's very easy if you own the OS and there is just one or
two controlled version of that OS. This applies both to Microsoft and
Apple. The benefit of closed source OS's. If you want to apply the
same principle, then you need to compare various Ubuntu releases to
each other.

The LSB (Linux Standards Base) and the FreeDesktop.org standards are
trying to make all distros more compliant with a set of standards -
making the life of any ISV and lone software developer MUCH easier.
LSB and FreeDesktop.org are supported by most mainstream distros (for
years already). If your distro doesn't, use something better, or email
the maintainers of that distro and demand better standardization.

Under Ubuntu 8.04 the 'lsb_release' command on it's own doesn't give
any usable output either. You need to specify a parameter.

eg:   $ lsb_release -a

Re: [Lazarus] Determining OS

2011-07-31 Thread 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.

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


$ lsb_release
LSB Version:n/a

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