Shell 解析日志文件并转换为csv所需的脚本

我需要解析一个包含TOP命令输出的文本/日志文件，并需要解析和存储来自该文件的数据。日志文件的格式如下：我对任何脚本语言都没有意见-

top - 11:48:02 up 8 days, 15:49,  7 users,  load average: 0.05, 0.05, 0.00

28983 root      10 -10  396m  69m  29m S 57.6  0.0  31:32.00 ras

我想要csv文件的格式-

[ top,time,CPU(% USER), CPU (%SYSTEM),Used Memory, PID, VIRT,RES,SHR,%CPU,%MEM,ProcessName]

下面是上述日志文件的示例-

top,11:48:02,1.7%us,1.9%sy,28256968k,28983,373m,46m,27m,2.0,0.0,ras
top,12:03:02,6.2%us,2.7%sy,29182584k,28983,387m,60m,29m,79.0,0.0,ras
top,12:33:03,5.1%us,2.5%sy,31074584k,28983,396m,69m,29m,57.6,0.0,ras

这可能是使用awk可以实现的最简单的解决方案之一：

$ awk '
/^top/ { printf "%s,%s,",$1,$3 }
/^Cpu/ { printf "%s%s",$2,$3 }
/^Mem/ { printf "%s,",$4 }
/^ *PID/ { getline; printf "%s,%s,%s,%s,%s,%s,",$1,$5,$6,$7,$9,$10; print $NF }' logfile
