MacOS – Are there replacements for the reg commad on Mac OS X 10.9

command linemacosunix

I believe reg existed on 10.8 and lower as documented here – https://developer.apple.com/library/prerelease/mac/documentation/Darwin/Reference/ManPages/man1/reg.1.html

However, in OS X 10.9 I only find man page but not the command. My requirement is to passively monitor the processor registers (dump them). It looks like 'reg' does that.

Is there an equivalent utility that I download somewhere for MAC OS X >= 10.9.

As far as I can tell reg is only available in Lion (/usr/bin/reg and /usr/share/man/man1/reg.1). I haven't been able to find it in any other system version in the 10.6 - 10.11 range.

Executing it in 10.10 works but I think some hardware data is missing. E.g my CPUs weren't recognized and I can't list any PCI device. Depending on the hardware your mileage will vary.

How to find all files that are larger than 1GB on the Mac HD

You can use the -x to avoid traversing mounted drives:

-x      Prevent find from descending into directories that have a device number different than that of the file from which the descent
        began.

You command should then be

$ sudo find -x / -type f -size +1G

Regarding the fact about the missing documentation: is not missing is just not easy to find. At the end of the PRIMARIES section of the man page

All primaries which take a numeric argument allow the number to be preceded by a plus sign ("+") or a minus sign ("-"). A preceding plus sign means "more than n", a preceding minus sign means "less than n" and neither means "exactly n".
