For the daily operation of AIX or Linux system administrator, the quantity of you managed servers and duplicate tasks will impact seriously your workload and efficency, and these are very baldness and boring. I aim to reduce the daily effort for every Unix/Linux system administrator, so we can release more free time to study some new skills. I named the set of scripts ztools, it includes the zcmd, ,zmksysb,zperf, znmon etc, it will provide you more reliable and simply administrator.
