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
#!/bin/bash
#
# 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
function viewconsumption {
ps aux | grep -v 'PID' | sed 's/[ ][ ][ ]*/ /g' | cut -d " " -f1-4 | sort | awk '
BEGIN{
userid = "None"
cpuUsage = 0
memUsage = 0
}
{
if(userid == $1) {
cpuUsage += $3
memUsage += $4
} else {
if (userid != "None") {
printf("%s %4.1f %4.1f/n", userid, cpuUsage, memUsage)
}
userid = $1
cpuUsage = $3
memUsage = $4
}
}'
}
function printResult {
awk '
BEGIN {
postcolor = "/033[0;39m"
}
{
userid = $1
cpuUsage = $2
memUsage = $3
if(cpuUsage >= 10 || memUsage >= 10) {
# red color
precolor = "/033[0;31m"
}
printf("%s%s /033[12G%4.1f /033[20G%4.1f%s/n", precolor, userid, cpuUsage, memUsage, postcolor)
precolor = "/033[0;39m"
}'
}
echo -e "USER /033[12G%CPU /033[20G%MEM"
echo"--------- ------ -----"
if [ "$1" == "--mem" ];then
key="-k 3 -n"

使用说明:
#以下输出均为“aix.unix-center.net”上的运行结果
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
tsingyee@aix bin# ./viewUsage.sh
