服务器评测为了方便自己查看CentOS上的各用户cpu和内存的使用比例，写了shell脚本。
viewUsage.sh

- # view the cpu and memory consumption of each user at the current time.
- # chenqy 20101126 v0.9
- # chenqy 20110115 v1.0 :
- # added the sort option: –reverse –mem –cpu

1. 不使用参数，直接调用，默认排序为按user名升序，cpu或mem的使用率超过10%时以红色字体显示：
#提示：大写字母开头会排在小写字母开头前面
