But it's called '/proc/ppc64' right now on lots of machines, so you can't go changing it.if test -d /proc/ppc64 .. is a quick way to check wether the system is 64bit or not. Similar to if test -d /proc/iSeries ..That's really ugly ! You really do that ? Gack...What way should I use?uname ? /proc/cpuinfo ? Whatever but not that.uname can be faked with powerpc32 or setarch. grep POWER /proc/cpuinfo might be an option. I think its only used in rpm preinstall scripts to reject 64bit kernel on 32bit systems or the other way around.
grep POWER won't do good on 970 among others. uname can be faked but why do you care ? In fact, is somebody is faking it, maybe it's because they -want- your scripts to think they are running on a 32 bits box.... I still think uname is the way to go. Ben.
