As the title says, how can I detect whether a script is running on AmigaOS4 (rather than some other OS)?

I was thinking of using IF EXISTS Env:AppDir , but that doesn't seem very reliable (apart from failing on OS4.0, it would be wrong if any other OSes or user decided to create an Env:AppDir folder).

So how else could I do it?

Version command without arguments. (I suppose it prints something like AmigaOS 4.0.)

Unfortunately neither of those solves my problem. For the moment I'm going to use IF EXISTS Sys:Kickstart unless anyone has any better ideas...

Go on, dirty up your scripts!

run >NIL: c:version >env:vertemp
search >NIL: env:vertemp PATTERN "AmigaOS 4."
if warn
skip gracefulexit
else
do funky stuff
endif

lab gracefulexit
delete env:vertemp



(Assuming version outputs Amiga OS4.#?)

No it doesn't. Also, I wasn't aware "Search" was a standard AmigaDOS 3.x command (so there seems no likelyhood it is also available on AROS & MorphOS nor works in the same way).

Maybe it works the other way around. Exclude it's MorphOS (version says "MorphOS) or AROS (dunno what AROS version command says) or OS3 (Well, version below 46) and assume it must be OS4 then.

uname ?? (probably needs SDK installed)

if exist sys:kickstart ??? (or do others have a kickstart dir?)

if exist sys:kickstart/kernel.kmod


[edit]

Oh I didn't spot you allready suggest edthe sys:kickstart one yourself.

Search command exists in 2.x/3.x: http://winuaehelp.back2roots.org/background/amigados.htm

It also exists in AROS and MorphOS and takes similar arguments:

Quote:

Ram Disk:> version MorphOS 3.2, Ambient 1.43, Kickstart 51.37 Ram Disk:> search ? FROM/M,SEARCH/A,ALL/S,NONUM/S,QUIET/S,QUICK/S,FILE/S,PATTERN/S,CASE/S,LINES/N

Search command in MorphOS is from AROS and should be 99% compatible.

Given that MorphOS and AROS do not have workbench per se, what happens if you test the result of

FAILAT 25
VERSION WORKBENCH VERSION 50 >NIL:
IF WARN
;Amigaos < 3.x
ENDIF

IF ERROR
; Not amiga os 4
ENDIF

It's been in the AmigaDOS user guide since 1986.

Ignition's makefile uses the command uname ...dunno how reliable it is on MorphOS and AROS though... here it is, should you find it useful:


#############################################
# find out the HOST operating system
# on which this makefile is run
HOST ?= $(shell uname)
ifeq ($(HOST), AmigaOS)
ifeq ($(shell uname -m), powerpc)
HOST = AmigaOS4
endif
ifeq ($(shell uname -m), ppc)
HOST = AmigaOS4
endif
endif

# if no host is identifed (no uname tool)
# we assume a AmigaOS build
ifeq ($(HOST),)
HOST = AmigaOS
endif

#############################################
# now we find out the target OS for
# which we are going to compile Ignition in case
# the caller didn't yet define OS himself
ifndef (OS)
ifeq ($(HOST), AmigaOS4)
OS = os4
else
ifeq ($(HOST), AmigaOS)
OS = os3
else
ifeq ($(HOST), MorphOS)
OS = mos
else
ifeq ($(HOST), AROS)
# now we find out which CPU system aros will be used
ifeq ($(shell uname -m), powerpc)
OS = aros-ppc
endif
ifeq ($(shell uname -m), ppc)
OS = aros-ppc
endif
ifeq ($(shell uname -m), i386)
OS = aros-i386
endif
ifeq ($(shell uname -m), i686)
OS = aros-i686
endif
ifeq ($(shell uname -m), x86_64)
OS = aros-x86_64
endif
else
OS = os4
endif
endif
endif
endif
endif


edit: sorry, pasting has completely f***ed up indentatio... how can i paste code?
