现在要编写一个脚本，实现将第三列内容按用户求和功能，脚本如下
#!/bin/sh
##################################
#脚本名称：CPUCHK_ECIFP_AP04_CPU_res.sh #
#作者:ZQC #
#功能：应用用户CPU使用率 #
#复核人: #
#日期:2011/12/05 #
##################################
ps aux > cpu.out
for v_u in `awk '{ print $1}' cpu.out |sort -u |sed '1,1d'`
do
v_cpu_idle_sum=0;
for v_cpu in `awk '{if ($1 == $v_u) print $3}' cpu.out`
do
v_cpu_idle_sum=$v_cpu_idle_sum+$v_cpu
done
v_result=`echo $v_cpu_idle_sum |bc -l `
echo $v_u ": CPU IS " $v_result
done
其中v_u的参数无法获取对应的值，不知道应该如何将参数传递到awk里，请高手支招，或者给出更好的写法，多谢多谢！ |
