Extension Attribute (is or isn't 64 bit)

[donmontalvo]

Has anyone created an Extension Attribute to flag computers that are or aren't booted into 64 bit?

PS, does it look like we need a "Casper Extension Attributes" mailing list? :)

Thanks,
Don

Not that I'm aware of but it's easy to grab with a "uname -a"

$ uname -a

That "x86_64" bit at the end is the relevant info. If it's 32-bit it'll be
i386.

Nice,

Thanks, I know this works too:

$ system_profiler | grep "64-bit Kernel and Extensions" 64-bit Kernel and Extensions: No

I was hoping a scripting guru could step in to whip up an Extension Attribute. It would fit nicely into the Resource Kit.

Hmmm...it would be nice to have an App Store utility from JAMF that lets you enter what you're looking for (64 bit = Yes or No) and produce an Extension Attribute. I'd happily pay $5 for it. :) Did you guys know Pixelmator made $1M one week after selling it through App Store...

(ok everyone get out of Tom's way...<g>)

Shows both the current setting and also what the machine is capable of. It's always worth limiting system_profiler to just the section that you want, to reduce overhead, or not to run if not necessary.

#!/bin/sh

intel="i386"
ppc="powerpc"
leopard="10.5"
snowleopard="10.6"

myOS=sw_vers -productVersion | cut -c 1-4
thisMach=uname -p

if [ "$thisMach" = "i386" ] && [ "$myOS" = "$snowleopard" ]
then

result1=ioreg -l -p IODeviceTree | grep firmware-abi | grep -o '".*>'
result2=system_profiler SPSoftwareDataType | grep 64-bit | sed 's/ {6}//'

result=echo "$result1 $result2"

elif [ "$thisMach" = "i386" ] && [ "$myOS" = "$leopard" ]
then

result=ioreg -l -p IODeviceTree | grep firmware-abi | grep -o '".*>'

elif [ "$thisMach" = "$ppc" ]
then

result=ioreg -l -p IODeviceTree | grep -i firmware | cut -d "<" -f 2 | sed 's/>//'

fi

echo "<result>$result</result>"

Hope this helps

FYI, wanted to kick start this thread again. Not sure what the best way is to have this EA only return a value if the hardware actually supports 64 bit. Or if that should be anything to worry about. :)

Using this...

#!/bin/sh

echo "<result>$( ioreg -l -p IODeviceTree | awk '/firmware-abi/ { split($0, line, """); printf("%s
", line[4]); }' )</result>"
