Although the man page does not mention the exit status, I think it's wrong that 'chcpu' exits OK when an action failed or when a bad CPU number was specified: $ ./chcpu -d 0 ; echo $? CPU 0 is not hot pluggable 0 $ ./chcpu -g 3 ; echo $? CPU 3 is not configurable 0 $ ./chcpu -e 4 ; echo $? CPU 4 does not exist 0 WDYT?
