Operating system in an emacs variable?

Operating system in an emacs variable?

[Carsten Dominik]

Hello,

I am looking for a variable or function in Emacs which gives me
information about the operating system the emacs process is running
on.  Basically, I would like to know if I am running Linux or MacOSX.
There must be a variable containing this information, but I could not
find it.  Anyone?

Thanks.

- Carsten

Check the `system-type' variable.

Ehud.

There are such variables, but which one you should be using depends on
why you want to know.  For instance, is it really the platform you
want to know, or is it the window system?  Should this test return the
same value for any emacs running in osx (terminal, x11, carbon), or
should it return different values for those three cases?

In short, what is it you're trying to accomplish with this test?

Oh? What a disapointment! The subject of this thread sounded really
really cool; imagine putting a whole operating system into an emacs
variable! That would have been really cool!

(defvar system
  (with-temp-buffer
    (insert-file-contents-literally
     (cond ((file-executable-p "/etc/init") "/etc/init")
	   ((file-executable-p "C:\\sys\\windows.exe")	; or whatever
	    "C:\\sys\\windows.exe")))
    (buffer-string))
  "The current operating system.")

Your notion of "operating system" is very restricted, to say the least.
Try something like "/vmlinuz" or some such instead (there's no standard
name for it).

I think on SunOS it was called /vmunix, but on my system (Solaris 7)
there's no such file.  On Solaris, process 0 is sched, for which I can't
find a binary, and process 1 is /etc/init.

Is it /stand/kernel there?  SysV uses a different naming convention
for these things...

A preposition is not a good thing to end a sentence with.

Nope:

/stand: No such file or directory
