great all fixed

i install ksh in gentoo and now it produces output from command line:
nagios@srvmonm /usr/lib/nagios/plugins $ ./check_cpu_stats2.3.6.sh
CPU STATISTICS CRITICAL : user=176% system=7.1%, iowait=0%, idle=2%, nice=21%, steal=0% | CpuUser=176%;70;90;0; CpuSystem=7.1%;40;60;0; CpuIowait=0%;30;40;0; CpuIdle=2%;0;0;0; CpuNice=21%;0;0;0; CpuSteal=0%;0;0;0;
it also works in nagios. Moreover, now it checks other linux systems through nrpe and draws graphs in nagios.
i can’t imagine anything else to tune up 🙂
